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.
- 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.
