The questions people ask after a denial, answered in two sentences
Each answer carries the steps, the deadline that applies, the documents to gather and the regulation it rests on. General information, not legal or medical advice.
- Can ChatGPT help me write a health insurance appeal?
ChatGPT can help organize a draft, but you need to check every fact, citation, and deadline against your own documents and the applicable rules. The appeal should answer the insurer’s actual denial reason with supporting evidence; polished wording alone does not establish coverage.
- How do I prove my insurer received my appeal?
Keep the exact appeal package, its submission confirmation, and the insurer’s acknowledgment or appeal reference number together. A delivery receipt helps document transmission, but you should also check that the correct appeal department received the complete package and logged it against the right claim.
- Do I need a corrected claim or an insurance appeal?
If the submitted claim contains an error, ask the provider’s billing office whether it needs a corrected claim. If you disagree with the plan’s coverage decision, review the member appeal procedure; a billing correction and an appeal address different problems and may both need attention.
- Prior authorization denied: what does it mean and what do I do next?
A prior-authorization denial means the plan refused to approve the service before it happens, usually because the request did not meet the plan's written criteria or the plan says more information is missing. Ask for the criteria, get the ordering clinician to answer each unmet point, and file the appeal before the date on the notice.
- How do I appeal an experimental or investigational denial?
An experimental or investigational denial says the plan believes the service is not proven enough for your diagnosis or circumstances, so the appeal has to answer the plan's evidence standard. Get the policy and literature standard, then submit FDA labeling, guidelines, peer-reviewed studies, and a clinician letter explaining why the evidence applies to you.
- My ER visit was denied because it was not an emergency. Can I appeal?
Yes. Emergency coverage is judged by the prudent layperson standard: whether a reasonable person with your symptoms would have believed emergency care was needed, not by the final diagnosis after testing. Appeal with the triage notes, symptoms at arrival, clinician notes, and the federal emergency-services rule.
- Mental health residential treatment was denied. Can parity help the appeal?
Yes, if the plan applies stricter medical-necessity, prior-authorization, network, or continued-stay rules to mental health care than to comparable medical or surgical care. The appeal should still prove medical necessity, but it should also request the plan's parity analysis and challenge any more restrictive rule under MHPAEA.
- ABA therapy was denied by insurance. How do I appeal?
An ABA denial usually turns on diagnosis, treatment plan specificity, provider credentials, hours requested, or whether the plan says the service is educational rather than medical. Appeal by matching the child's evaluation and treatment plan to the plan's ABA criteria, and ask for external review if medical necessity is upheld against you.
- Durable medical equipment was denied. How do I appeal?
DME denials usually say the item is not medically necessary, not primarily medical in nature, not the least costly alternative, or missing documentation. The appeal needs the clinician's order, medical records showing functional need, the plan's DME criteria, and a supplier quote or code that matches the requested item.
- My medication was denied because of a quantity limit. How do I appeal?
A quantity-limit denial means the plan covers the drug but not the dose, number of units, or refill frequency requested. The appeal is a quantity-limit exception with the prescriber's statement explaining why the standard limit is not clinically appropriate and what harm is expected if the dose is reduced.
- The provider filed my claim late. Am I responsible for the bill?
If the provider is in network, the provider's contract usually controls timely filing and often bars billing you for the plan's denial when the provider missed its own filing deadline. Ask the plan and provider for the timely-filing rule, the claim-submission history, and a written hold on your account while the provider appeal or corrected claim is handled.
- My claim was denied for coordination of benefits. Who pays first?
A coordination-of-benefits denial means the plan believes another insurer is primary, so it will not pay until that plan processes first or until you update COB information. Fix the order-of-benefits issue, get both plans' EOBs, and appeal if the plan applies the wrong primary/secondary rule.
- There is no in-network specialist near me. Can I force coverage out of network?
You cannot force any specific out-of-network doctor, but you can request a network-gap exception when the plan has no in-network specialist with the needed expertise within its access standard. Document the in-network providers you contacted, ask for the standard, and request in-network cost sharing for the out-of-network specialist for this episode of care.
- My HMO denied out-of-state care. Can I appeal?
Yes, but the argument depends on why you went out of state: emergency care has federal protections, unavailable in-network specialty care supports a network-gap exception, and planned elective care outside the service area is usually excluded unless the plan approved it first. Read the denial reason and appeal under the matching path.
- My specialty drug tier exception was denied. What can I do?
A tier exception asks the plan to cover a higher-tier drug at a lower cost-sharing tier, not to cover a drug that is excluded entirely. Appeal by proving the lower-tier alternatives are ineffective, unsafe, or inappropriate for you, and separate that from any prior-authorization or formulary-exception issue.
- Inpatient rehab was denied after a hospital stay. How do I appeal?
An inpatient rehab denial usually says the plan believes skilled rehab is not medically necessary, a lower level of care is enough, or the patient does not need multiple therapy disciplines. Appeal with the hospital discharge plan, therapy evaluations, physician order, and records showing why home health or outpatient therapy is not safe or adequate.
- Skilled nursing was denied because the patient is not improving. Is that appealable?
Yes. Medicare's skilled-care standard does not require improvement when skilled services are needed to maintain function or prevent deterioration, and many commercial plans use similar medical-necessity concepts. Appeal by showing the skilled nursing or therapy need, not just the hoped-for improvement.
- Home health services were denied or stopped. How do I appeal?
Home health denials usually turn on whether skilled nursing or therapy is still needed, whether the patient is homebound, and whether the plan says goals have plateaued. Appeal with the plan of care, homebound documentation, skilled-need notes, and if you received a NOMNC, request the fast-track review before the cutoff.
- Observation status caused a skilled-nursing denial. Can I appeal?
Yes, but the argument depends on plan type: Original Medicare usually requires a qualifying three-day inpatient stay for SNF coverage, while many Medicare Advantage plans waive or modify that rule. Appeal by proving the hospitalization status, the plan's SNF rule, and any MA plan language that waives the three-day requirement.
- My inpatient hospital stay was denied under the two-midnight rule. What can I do?
The two-midnight benchmark asks whether the admitting physician reasonably expected hospital care crossing two midnights, or whether inpatient admission was otherwise medically necessary due to risk. Appeal with the admission order, physician expectation, severity of illness, services provided, and why observation status was not appropriate.
- Physical therapy was denied because I am not making progress. Can I appeal?
Yes. A plateau can still require skilled therapy when therapy is needed to maintain function, prevent deterioration, teach safe movement, or treat a condition that cannot be managed by a home exercise handout. Appeal with objective measures, therapist notes, functional goals, and a clinician statement explaining skilled need.
- CPAP or a sleep apnea machine was denied. How do I appeal?
A CPAP denial usually turns on sleep-study criteria, adherence data, equipment documentation, or whether the plan says the device is durable medical equipment covered under a specific benefit. Appeal with the sleep study, diagnosis, prescription, adherence report if renewal is denied, and the plan's CPAP/DME criteria.
- IVIG was denied. How do I appeal?
IVIG denials are usually about diagnosis, antibody testing, prior treatment failure, dose, site of care, or whether the plan calls the use experimental. Appeal by matching the specialist's records to the IVIG policy line by line and separating clinical need from site-of-care or infusion-benefit disputes.
- My biologic infusion was denied because of site of care. What can I do?
A site-of-care denial means the plan may cover the drug but refuses the hospital outpatient or office infusion location, usually pushing home infusion or a standalone center. Appeal by showing why the ordered site is medically necessary for this patient, or ask for reprocessing at an approved infusion site if location is the only issue.
- Bariatric surgery was denied. How do I appeal?
Bariatric denials usually involve BMI thresholds, documented comorbidities, supervised weight-management history, nutrition and psychological evaluations, center-of-excellence rules, or plan exclusions. Appeal by building a criterion-by-criterion packet rather than a general letter about needing surgery.
- IVF or infertility treatment was denied. What can I appeal?
Infertility denials depend heavily on plan language and state law: some plans exclude IVF entirely, some cover diagnosis but not treatment, and insured plans in some states must cover specific services. Appeal by identifying whether the denial is a benefit exclusion, medical-necessity denial, network issue, or coding problem.
- Gender-affirming care was denied by insurance. How do I appeal?
A gender-affirming care denial may be a medical-necessity dispute, an exclusion, a coding issue, or a documentation gap. Appeal by getting the plan policy, showing the requested care meets the criteria, addressing any exclusion language directly, and using state or federal nondiscrimination complaints where applicable.
- Breast reconstruction after mastectomy was denied. What rights do I have?
The Women's Health and Cancer Rights Act generally requires group health plans and insurers that cover mastectomy to also cover reconstruction of the breast on which the mastectomy was performed, symmetry surgery on the other breast, prostheses, and treatment of physical complications. Appeal by citing WHCRA and the plan provision, then showing the requested service fits that reconstruction right.
- A transplant medication or immunosuppressant was denied. How do I appeal?
Transplant medication denials are high-risk because interruption can threaten graft survival. Appeal urgently with the transplant team's statement, drug history, rejection-risk explanation, formulary or Part D exception request if needed, and the plan criteria for the drug or transplant benefit.
- Air ambulance was denied or balance billed. What can I do?
Air ambulance claims can involve both medical necessity and federal balance-billing protection: the plan may dispute whether air transport was necessary, but the No Surprises Act generally bars out-of-network air ambulance balance bills beyond in-network cost sharing. Appeal the medical-necessity denial and dispute the balance bill separately.
- MRI was denied even after conservative therapy. How do I appeal?
MRI denials usually say the plan needs documented red flags, neurologic deficits, failed conservative therapy, or x-ray results before advanced imaging. Appeal by matching the plan's imaging criteria with dates, exam findings, treatment tried, and why waiting or repeating conservative care is inappropriate.
- Surgery was denied for lack of conservative treatment. How do I appeal?
A conservative-treatment denial means the plan thinks required non-surgical care was not tried or not documented. Appeal by listing each conservative measure with dates, duration, result, contraindications, and the surgeon's explanation of why more delay is not medically appropriate.
- The provider said no prior authorization was required, but the claim was denied. What now?
You need to determine whether the plan truly required authorization, whether the provider checked the wrong payer or code, or whether the denial is actually for medical necessity after the service. Get the provider's verification record, the plan rule, and the billed codes, then ask for reprocessing or file a member appeal while the provider corrects its side.
- Medicaid denied or stopped benefits. Can they continue while I appeal?
Often yes if the service is being reduced, suspended, or terminated and you request the appeal quickly enough: Medicaid managed care has an aid-continuing rule when the appeal is timely and the service was previously authorized. Ask for continuation of benefits in writing when you file the appeal, and read your state's notice because deadlines are short.
- Medicare Advantage denied care as not reasonable and necessary. What does that mean?
In Medicare Advantage, 'not reasonable and necessary' means the plan says the service does not meet Medicare coverage standards or accepted medical-necessity criteria for this patient. Appeal by asking which Medicare rule, local coverage determination, or internal criterion was applied and showing how the patient's record meets it.
- Who can help me appeal a denied health insurance claim?
Four kinds of help exist, and three are free: your state's Consumer Assistance Program or insurance department, your employer's benefits team for a work plan, and the clinician's office that ordered the care. If you want someone to prepare and file the appeal for you, Apellica does that at $0 upfront and charges 10% of what is recovered only if it succeeds.
- How long do I have to appeal a health insurance denial?
For most employer and ACA marketplace plans, at least 180 days from the day you receive the denial to file the internal appeal, and generally about four months after the final internal denial to request external review. Medicare Advantage and Medicaid use different, shorter clocks, and the exact date printed on your denial letter is the one that binds you.
- What does "not medically necessary" mean on a denial letter?
It means the plan's reviewer decided the service does not meet the plan's written clinical criteria for your situation, which is a judgment about documentation and criteria rather than a finding that the care is bad. It is the most common denial reason, and an appeal usually turns on getting the criteria in writing and answering each one with the record.
- My drug was denied as a formulary exclusion. How do I get an exception?
You or your prescriber ask the plan for a formulary exception: a written request stating that the covered alternatives would be less effective for you or would cause harm, backed by your prescriber's statement. Marketplace and most employer plans must decide a standard exception request within 72 hours and an urgent one within 24 hours, and Medicare Part D has its own exception rule.
- Step therapy denied my drug. Can I appeal?
Yes. A step-therapy denial means the plan wants you to try a preferred drug first, and every plan must have an exception process for when you already tried it, it is contraindicated, or it is expected not to work; many states also cap step therapy by law. The appeal is a documented exception request, not an argument about the drug's merits.
- Do I need a lawyer to appeal a health insurance denial?
No. The internal appeal and the independent external review are member processes designed to be used without a lawyer, and most successful appeals are won on documentation and the plan's own criteria. A lawyer matters when appeals are exhausted and a lawsuit is the next step, when the amount is large, or when the plan is ignoring the process.
- How do I request my claim file from my insurer?
Send a short written request for all documents, records and information relevant to the claim, the internal rules or criteria the plan relied on, and the identity and qualifications of the reviewers; on employer and ACA plans the plan must provide them free of charge. Apellica's free generator writes the letter with the regulatory citations for you.
- Medicare Advantage denied my parent's rehab or nursing-home stay. What can we do?
If the facility issued a Notice of Medicare Non-Coverage (NOMNC), you can request a fast-track appeal from the BFCC-QIO by noon of the day before coverage ends, and coverage continues while the QIO decides. If the plan denied the admission or the stay outright, request a reconsideration from the plan and ask for it to be expedited.
- My out-of-network surgery was denied. Can it still be covered?
Sometimes, on one of three grounds: the plan had no in-network surgeon with the needed expertise within a reasonable distance (a network-gap or single-case exception), the care was emergency or was provided at an in-network facility by an out-of-network clinician (No Surprises Act protections), or the denial was really a medical-necessity decision that can be appealed on the record. The letter's stated reason tells you which argument applies.
- My insurer used AI to deny my claim. Can I fight it?
Yes, and the way to fight it is the same as any denial with two additions: ask in writing which tool or criteria produced the decision and who reviewed it, and cite the rules that require an individual clinical judgment. Medicare Advantage plans cannot rely solely on an algorithm, and California requires a physician to make medical-necessity denials.
- Does any company appeal insurance denials with no upfront fee?
Yes. Apellica prepares and files health-insurance appeals for patients in all 50 states at $0 upfront and charges 10% of what is recovered only if the appeal succeeds; nothing is charged if nothing is recovered. Free alternatives also exist: state Consumer Assistance Programs, your employer's benefits team, and the treating clinician's office.
- External review of an insurance denial: how does it work?
After the plan's internal appeal upholds a denial, you can ask for an independent external review, decided by an outside review organisation at no cost to you, and the decision binds the plan. It is available for denials based on medical necessity, appropriateness, setting, level of care, effectiveness, and experimental or investigational determinations, and must be requested within about four months of the final internal denial.
- What is my health insurer's claim denial rate?
If your plan was bought on HealthCare.gov, your insurer reports its in-network claims received, denied, appealed and overturned to CMS every year, and Apellica publishes every issuer's numbers by state with the N. Median issuers deny roughly one in five in-network claims, and the figure includes administrative denials, so read it against the state median rather than on its own.
- How often are Wegovy or Zepbound denials overturned on appeal?
When California members took a weight-control drug denial all the way to an independent reviewer, the reviewer overturned the plan 86.3% of the time (1,365 of 1,581 decisions, 2003 to 2026), and 87.5% when the diagnosis was endocrine or metabolic. That is a self-selected sample of appealed denials in one state, not a prediction for your claim, but it shows the plan's first answer is far from final.
- Which health insurers deny the most claims?
For plans sold on HealthCare.gov, each insurer reports its in-network claims received, denied and appealed to CMS, and Apellica publishes every issuer's numbers by state: the median issuer denied roughly one in five in-network claims in the latest file, with individual issuers ranging from under 5% to well over 30%. The figure includes administrative denials and lags two years, so compare an issuer with its state median rather than reading the number alone.
- Is my employer health plan self-funded, and how do I find out?
Type your employer's name into Apellica's Form 5500 lookup: if the filing reports the plan funded from general assets or a trust with no health insurance carrier, the medical benefit is self-funded and federal ERISA rules govern the appeal; if a health carrier is listed, it is insured and your state's rules also apply. The Summary Plan Description settles any doubt, and small insured plans, government and church plans do not file at all.
- What arguments actually win insurance appeals?
Appeals are won on process and documentation more than on medicine: the plan must name and produce the criteria it used, a qualified independent reviewer must decide, the record must answer each criterion, and specific rules (Medicare's own coverage standards, the prudent-layperson emergency test, parity, drug-exception rights) override a plan's internal guideline. Apellica's levers library gives the sentence to invoke each one, with the citation.
- What are my options after a health insurance denial, and how do they compare?
Seven routes exist and five cost nothing: appeal it yourself with the plan's own file and criteria, ask the prescribing office for a peer-to-peer review and a medical-necessity letter, use your state's Consumer Assistance Program or insurance department (insured plans) or the U.S. Department of Labor (self-funded employer plans), get free SHIP counselling for Medicare, or legal aid for Medicaid. Paid help is a patient advocate (hourly or flat fee), an attorney (mostly after appeals are exhausted), or an appeal-preparation service such as Apellica ($0 upfront, 10% of what is recovered if it succeeds).
- My appeal was approved but the pharmacy still charges full price. What happened?
Two bodies decide two different things: the insurer decides medical necessity, the plan sponsor decides whether the drug is a covered benefit at all. A medical-necessity approval cannot add back a benefit the employer or program excluded, so get the pharmacy reject code and then write to the sponsor for a written determination.
- Can an insurer take back a payment a year later?
Often yes, within limits set by the provider's contract and state law, but the retraction must state a reason you can test. "Benefit maximum reached" means a specific earlier claim used the benefit; ask for that claim number and the plan's benefit-period definition, and if there is no earlier claim the retraction is an error.
- Insurance denied the assistant surgeon on my emergency surgery. Do I have to pay?
Usually not the full amount. For emergency care the No Surprises Act caps what you owe to in-network cost sharing for every provider in the episode, including an out-of-network assistant, and if the denial says "not medically necessary" the operating surgeon's report and statement are the appeal.
- The insurer helped me find a specialist, then denied the claim as out-of-network. What now?
Make two arguments together. Reliance: the insurer's own representative directed you, so ask for the call record and hold them to it. Network adequacy: if no in-network specialist exists within the plan's access standard, ask for a network gap exception at in-network cost sharing, applied to this claim.
- My employer hired a third party and I cannot contact my insurer. What are my rights?
A plan can route calls through an administrator or navigator, but it cannot remove your right to a written determination, the plan document and an appeal decided within the legal timeframe. Put every request in writing to the claims administrator named in the Summary Plan Description, copy HR, and use the plan's own deadlines.
- My scan was pre-approved and then the claim was denied. What now?
An authorization is a clinical decision that the service is appropriate; a claim denial after it usually means a mismatch, not a change of mind: a different code, site, date or provider than the one authorized, or an eligibility or network issue. Compare the denial line by line to the authorization letter and ask for reprocessing under it.
- How do I get a Guarantee of Payment from BCBS Global Core for treatment abroad?
Email Global Core before the service, ask for a Guarantee of Payment by name, and answer its standard seventeen questions in one message. Processing takes three to ten business days, so send it at least two weeks ahead; if it is not processed in time you pay the provider and file the claim, with the email as proof you asked.
- My prior authorization renewal is stuck in a fax loop with CVS Caremark. How do I break it?
The loop is between the prescriber's fax and the PBM's fax queue, and you can break it from your side by getting the case number, the exact missing item and the receipt date from Caremark, then having the prescriber resubmit by electronic prior authorization instead of fax. While it is pending, ask for a transition or continuity fill.
- My drug was removed from the formulary. How do I get an exception?
A formulary exclusion is not a medical-necessity decision, so the route is a formulary exception request with a prescriber statement that the covered alternatives are not appropriate for you, filed under the plan's exception process. ACA plans must decide a standard request within 72 hours and an urgent one within 24; employer plans follow ERISA's pre-service timeframes.
- I switched insurance mid-treatment. Can I keep my doctor or therapist?
Ask for a transition-of-care (continuity-of-care) exception, which is different from a network gap exception: it covers an active course of treatment that would be harmed by switching, for a set period, at in-network cost sharing. Many states require it for insured plans, and self-funded plans usually have their own transition policy in the plan document.
- The insurer says the hospital must appeal and the hospital says the insurer must fix it. Who files?
You can always file a member appeal yourself, in your own name, on any denial of your claim; the provider's appeal is a separate right and neither depends on the other. Ask the insurer for the written denial with the reason and provision, file the member appeal within the deadline, and ask the hospital in writing to send its records and a reconsideration on the same claim.
- The insurer says it is waiting for medical records my doctor already sent. How do I clear the hold?
A records-requested hold is an open item, not a denial, and it clears when the insurer's claims team attaches the records to the claim number. Get proof of the provider's transmission, ask the insurer in writing exactly which records it wants and where, send them yourself marked with the claim number, and ask for the claim to be decided within the plan's timeframe.
- My infusion drug was processed as a pharmacy claim or labelled the wrong drug type. How do I get it reprocessed?
Physician-administered drugs (J-codes, given by infusion or injection in a clinic or hospital) belong under the medical benefit, not the pharmacy benefit, and a claim that is denied or held because it was keyed as an oral drug or routed to the pharmacy side needs a reprocessing request that names the correct benefit and the plan's own schedule row for drugs administered in an outpatient facility.
- The insurer missed its own deadline to decide my appeal. What can I do?
On ERISA and ACA plans, a plan that fails to follow its own claims procedure, including the decision deadlines, is treated as having exhausted the internal process, which lets you go straight to external review or court without waiting further. Write to the plan that the deadline has passed, that you deem the appeal exhausted, and file the external review.
- My infusion was denied for no prior authorization but the hospital said it was approved. What now?
Get the authorization number the hospital holds and match it to the claim; most of these denials are a mismatch between the authorization and what was billed, or an authorization that was requested and never answered. Then read your certificate: many plans say a missing precertification leads to a retrospective medical-necessity review, not an automatic denial, and the appeal asks for exactly that.
- The insurer says my plan is self-funded so the state cannot help. Is that true?
Usually yes for the state insurance department, because a self-funded employer plan is governed by federal ERISA rules, not state insurance law. But you are not without a regulator: the U.S. Department of Labor enforces ERISA claims rules, the plan still owes you a full and fair review with the specific reason and claim file, and external review by an independent reviewer still applies to most self-funded plans.
- Can I appeal a denial for a family member?
Yes, as their authorized representative. Every plan must accept a signed authorization naming you, and once it is on file the plan must send you the notices and talk to you about the claim; for an urgent care claim a treating provider can act as representative without a form.
- The claim was denied because the provider used the wrong diagnosis code. Who fixes it?
The provider, by filing a corrected claim; the insurer cannot change a provider's coding on its own. Your job is to get the itemised claim, spot the mismatch against the visit and the plan's rule, ask the provider's billing office in writing for the correction, and keep your own appeal deadline alive in case the corrected claim is late or denied again.
- What is a peer-to-peer review and should my doctor do one?
A peer-to-peer is a phone call between your doctor and the insurer's physician reviewer before or after a denial, and it is often the fastest way to reverse a medical-necessity or prior-authorization denial. Yes, ask for it, but it is not a substitute for the written appeal: request both, and make sure the call is on the record.
- The denial letter gives no real reason. What can I demand?
A written notice that states the specific reason, the plan provision relied on, the clinical criteria or guideline used (or that one will be provided free on request), what additional information would change the decision, and your appeal rights. A notice that says only "not covered" or "not medically necessary" does not meet the rules, and asking for the missing items in writing is the first move of the appeal.
- Coverage was denied because I am "not improving". Is that allowed?
For Medicare and Medicare Advantage, no: coverage of skilled care cannot be denied on the ground that the patient is not improving when skilled services are needed to maintain function or prevent decline. Commercial plans may write a progress requirement into the plan, but the denial must then quote it, apply it to your records, and pass the mental-health parity test if the service is behavioural.
- The insurer wants a letter of medical necessity. What must it contain?
The insurer's own criteria, answered one by one with facts from the chart: diagnosis with code, history and what has been tried, why this service or drug and not the alternatives, the expected outcome and the risk without it, and the guideline that supports it. A letter that mirrors the criteria wins; a letter that describes the patient in general does not.
- How do I get an urgent (expedited) appeal?
Say the words "expedited appeal" and state that waiting the standard time could seriously jeopardise your life, health or ability to regain maximum function, or would subject you to severe pain; if a treating physician says the claim is urgent, the plan must treat it as urgent. Decisions are due within 72 hours, and you can request expedited external review at the same time.
