Molina inpatient rehab denied: how to appeal

Quick answer

If Molina Healthcare denied your inpatient rehabilitation, you can appeal, and the plan must give you its file and the criteria it used. Filing windows by plan type: 60 days from the notice (Medicaid managed care); at least 180 days (insured and Marketplace plans); 65 days from the notice (Medicare Advantage). The date printed on your denial notice controls; it can only be later than these floors, never earlier.

Why Molina Healthcare denies inpatient rehabilitation

Molina Healthcare is concentrated in Medicaid managed care, with smaller marketplace and Medicare Advantage footprints. Appeal pathways depend heavily on the underlying line of business and the state Medicaid agency that contracts with Molina.

For inpatient rehabilitation specifically: Inpatient rehabilitation facility (IRF) stays are denied at admission or cut short mid-stay, usually on the argument that a lower level of care such as a skilled nursing facility would do. The appeal turns on the medical record showing why intensive, physician-supervised rehabilitation is required.

The law that controls this appeal

For Medicare and Medicare Advantage, the IRF coverage criteria at 42 CFR 412.622(a)(3): a need for active and ongoing therapy in at least two disciplines (one being PT or OT), an intensive program (generally 3 hours a day at least 5 days a week), close physician supervision, and a reasonable expectation of measurable improvement. Medicare Advantage plans may not apply stricter internal criteria than traditional Medicare (42 CFR 422.101(b)). Commercial plans apply their own level-of-care criteria (often MCG or InterQual), which must be disclosed on request under 29 CFR 2560.503-1 and 45 CFR 147.136.

Molina Healthcare appeals: the rule, the deadline and the next level, by plan type

Which row applies depends on the plan you hold, not on Molina Healthcare's brand. Your ID card, the Summary Plan Description and the denial letter say which.

Plan type	Rule that governs	File your appeal within	The plan must answer	If the plan says no again
Medicaid managed care plan A Medicaid plan run by the carrier under a state contract. The card says Medicaid, Medi-Cal, STAR, HealthChoice or your state's programme name.	42 CFR Part 438, Subpart F (plan appeals) and 42 CFR Part 431, Subpart E (state fair hearings).	60 calendar days from the date on the notice of adverse benefit determination to request the plan's appeal (42 CFR 438.402(c)(2)(ii)). State fair hearing: within 120 calendar days of the plan's appeal decision (§ 438.408(f)(2)).	Standard appeal: 30 calendar days. Expedited: 72 hours (42 CFR 438.408(b)).	A state fair hearing after the plan's single level of appeal (§ 438.402(b)); some states add an external medical review. Benefits continue during the appeal if you ask within 10 calendar days of the notice (§ 438.420).
Fully insured employer, individual or Marketplace plan The carrier holds the risk and is licensed in your state. Small employers and almost all individual and HealthCare.gov plans.	45 CFR 147.136 (Public Health Service Act § 2719), which applies the 29 CFR 2560.503-1 procedures and adds state external review; state insurance law on top.	At least 180 days from the denial (45 CFR 147.136(b); 29 CFR 2560.503-1(h)(3)(i)).	Urgent care: 72 hours. Pre-service: 30 days. Post-service: 60 days. Prior-authorization decisions by Marketplace issuers from 2026: 72 hours expedited, 7 calendar days standard (CMS-0057-F).	External review through your state's process, or the federal process where the state has none, generally within 4 months of the final internal denial (45 CFR 147.136(c), (d)). The state insurance department and its Consumer Assistance Program take complaints.
Medicare Advantage (Part C) A private plan that replaces Original Medicare. The card says Medicare Advantage, HMO, PPO or PFFS.	42 CFR Part 422, Subpart M (§§ 422.560 to 422.634). Coverage decisions must follow Original Medicare rules (42 CFR 422.101).	65 calendar days from the date on the denial notice to request the plan's reconsideration (42 CFR 422.582, as amended effective 1 January 2025).	Expedited: 72 hours. Standard pre-service: 30 days (7 days for Part B drugs). Payment: 60 days (42 CFR 422.590).	If the plan does not fully reverse itself it must send the case to the Independent Review Entity on its own (42 CFR 422.592); then an ALJ hearing when the amount in controversy meets the annual threshold, the Medicare Appeals Council and federal court. State external review does not apply.

Medicaid managed care plan

What you can demand. Free copies of the case file, medical records and the criteria used, before and during the appeal (42 CFR 438.406(b)(5)). Children under 21 have EPSDT rights to medically necessary care (42 U.S.C. 1396d(r)(5)).

How to open the appeal. Cite 42 CFR 438.402 and 438.406(b)(5): request the case file and the criteria, ask for continued benefits within 10 days, and reserve the state fair hearing.

Fully insured employer, individual or Marketplace plan

What you can demand. The plan must give you the claim file, the criteria it applied and any new evidence or rationale before the final decision, free of charge (45 CFR 147.136(b)(2)(ii)(C); 29 CFR 2560.503-1(h)(2)(iii)).

How to open the appeal. Cite 45 CFR 147.136 and 29 CFR 2560.503-1: request the claim file and the criteria, note the decision clocks, and name the state external-review right.

Medicare Advantage (Part C)

What you can demand. The plan may not apply internal criteria that are more restrictive than Medicare's national and local coverage determinations, and must decide medical necessity on your individual circumstances (42 CFR 422.101(b), (c)). You can ask for the case file and the criteria used.

How to open the appeal. Cite 42 CFR 422.582 and 422.101(c): the plan must decide on your individual circumstances under Medicare coverage rules, and must forward an unfavorable reconsideration to the IRE itself.

What Molina Healthcare denies for inpatient rehabilitation

The inpatient rehabilitation services most often denied:

IRF admission after stroke, brain injury, spinal cord injury, hip fracture, or major joint replacement
Continued-stay days once the plan decides goals can be met at a lower level of care
Transfer from an acute hospital to IRF instead of a skilled nursing facility
Rehab after cardiac surgery, transplant, or prolonged ICU stay (deconditioning)

Why inpatient rehabilitation claims get denied

A typical Molina Healthcare inpatient rehabilitation denial almost always cites one of these reasons. Each one maps to a specific rebuttal in the appeal:

Plan says a skilled nursing facility or home health is 'the appropriate level of care'
Therapy intensity (3 hours a day) is judged not tolerable or not required
No documented need for daily physician supervision
Pre-admission screening or physician certification missing from the record
Medicare Advantage plan applied internal criteria beyond the IRF rule

The Molina Healthcare appeal process

Appeal levels: Plan internal appeal, then state Medicaid fair hearing for Medicaid lines. Marketplace: internal then federal external review. Medicare Advantage: federal 5-level ladder.

Carrier timing: Medicaid filing windows are state-specific, commonly 60-120 days from the action notice. Continuation-of-benefits typically requires filing within 10 days. Marketplace: 180 days internal, 4 months external.

Inpatient rehab timing: Medicare Advantage: request reconsideration within 65 days of the notice; expedited decisions within 72 hours (42 CFR 422.582, 422.584). When an IRF stay is being ended, the facility issues a Notice of Medicare Non-Coverage and the patient can ask the QIO for fast-track review by noon of the day before coverage ends (42 CFR 422.626). Commercial and employer plans: at least 180 days to file an internal appeal; urgent pre-service decisions within 72 hours (29 CFR 2560.503-1; 45 CFR 147.136).

What we know about Molina Healthcare: Molina appeals are most often won at the state fair-hearing stage. We preserve continuation-of-benefits where the timing permits and brief the case to the state's administrative law judge.

Common Molina Healthcare denial patterns for inpatient rehabilitation

State Medicaid fair-hearing escalation. Molina Medicaid denials must first run through the plan's internal grievance and appeal process. After plan-level denial, the member has the right to a state Medicaid fair hearing, a separate administrative track that frequently overturns prior-auth and medical-necessity denials.
Continuity-of-care protections. Medicaid rules generally require continuation of previously authorized services pending the outcome of a timely-filed appeal. Members who file within the state's continuation window (often 10 days from the action notice) preserve services during the appeal.
EPSDT-based denials in pediatric cases. For Molina members under 21, federal EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) requirements broaden coverage beyond the adult benefit. Many pediatric denials reverse on appeal once the EPSDT framework is cited.

How to win your Molina Healthcare inpatient rehabilitation appeal

Strategy for inpatient rehabilitation: Get the rehabilitation physician's admission note, the pre-admission screening, and the therapy evaluations. Map each element of the IRF criteria to a page in the record: multiple disciplines, intensity, medical supervision, expected improvement. For Medicare Advantage, cite 42 CFR 422.101(b)(2), which binds the plan to traditional Medicare coverage rules. If the patient is already admitted and the plan is ending coverage, use the fast-track review (see Timing) before the effective date so services continue during review.

Filed against Molina Healthcare, that strategy rides on this procedural spine:

Procedural-rights anchor. Cite 42 CFR 438.402 and 438.406(b)(5): request the case file and the criteria, ask for continued benefits within 10 days, and reserve the state fair hearing. If your Molina Healthcare coverage is a different plan type (Fully insured employer, individual or Marketplace plan, Medicare Advantage), use that row of the table above instead; the rule and the deadline change with the plan, not the carrier.
Criteria-disclosure demand. Molina Healthcare frequently denies on "not medically necessary" without disclosing the clinical criteria applied. Once disclosed, those criteria become the rebuttal map.
Controlling-standard citation. For Medicare and Medicare Advantage, the IRF coverage criteria at 42 CFR 412.622(a)(3): a need for active and ongoing therapy in at least two disciplines (one being PT or OT), an intensive program (generally 3 hours a day at least 5 days a week), close physician supervision, and a reasonable expectation of measurable improvement. Medicare Advantage plans may not apply stricter internal criteria than traditional Medicare (42 CFR 422.101(b)). Commercial plans apply their own level-of-care criteria (often MCG or InterQual), which must be disclosed on request under 29 CFR 2560.503-1 and 45 CFR 147.136.
Treating-provider attestation. A letter from the treating physician addressing each criterion in Molina Healthcare's own policy language. This is the single strongest evidentiary element.
Requested action. A specific demand to reverse the inpatient rehabilitation denial and approve the service, not a general "please reconsider."

What a inpatient rehabilitation appeal can recover

Typical recovery for inpatient rehabilitation cases runs An IRF stay is billed per day at rates that make even a short denied stay a significant sum; the amount at stake depends on the length of stay and the plan's allowed amount.. The exact figure depends on the specific service and your plan's contracted rates.

Molina Healthcare inpatient rehabilitation appeals: frequently asked questions

Can Molina Healthcare send me to a nursing home instead of inpatient rehab?

The plan can propose it, and you can appeal it. The question the reviewer must answer is whether the record shows a need for intensive, multidisciplinary, physician-supervised rehabilitation. If it does, a skilled nursing facility is not an equivalent level of care.

How fast does a Molina Healthcare inpatient rehab appeal move?

Pre-admission and continued-stay disputes qualify as urgent because delay can jeopardize recovery. Urgent decisions are due within 72 hours. For Medicare Advantage, a fast-track QIO review requested before the effective date keeps coverage in place during the review.

Does the three-hour rule mean I have to do three hours of therapy every day?

The Medicare IRF criteria describe an intensive program that generally means 3 hours a day at least 5 days a week, but the rule allows the intensity to be measured over a 7-day period in individual cases and does not require it from day one for every patient. The physician's documentation of why the patient needs and can participate in the program is what matters.

What if Molina Healthcare already cut off my stay?

Appeal anyway. A retrospective appeal can recover days the plan refused to cover, and the medical record from those days is the evidence.
