IRF Admission denied as duplicate or overlapping therapy by UnitedHealthcare?

UnitedHealthcare's specific coverage criteria for irf admission are defined in its own published medical/coverage policy and the FDA-approved prescribing label. A successful appeal documents that your medical records satisfy each criterion those sources list — confirmed diagnosis, any required prior treatments (with dates and outcomes), and clinical severity. If the exact criteria weren't included with your denial, request them in writing; your appeal then maps each requirement to the matching fact in your chart.

## Why UnitedHealthcare Denied Your IRF Admission as "Duplicate Therapy" — and How to Appeal

Inpatient Rehabilitation Facility (IRF) admission denials framed as "duplicate therapy" typically claim that the rehabilitation services provided in an IRF duplicate services already being received in another setting — for example, a skilled nursing facility (SNF) or outpatient therapy. This framing is almost always incorrect for IRF-level care, because IRF admission requires an intensity of service (multi-disciplinary team, physician oversight, hours of daily therapy) that no other post-acute setting provides. The denial is usually a clinical-criteria question dressed up as a classification question.

## Federal Appeal Rights

IRF admission is a Medicare Advantage or commercial insurance coverage decision subject to full federal appeal rights. Under ACA §2719 and ERISA §503, you may file an internal appeal and then an independent external review with a certified IRO. The external review window is generally 4 months from the final internal denial. If the patient is currently hospitalized or faces urgent discharge, request an expedited internal appeal (typically resolved within 72 hours) and an expedited external review simultaneously.

## Concrete Appeal Steps

1. Obtain the denial letter in full and identify exactly which prior or concurrent service UHC claims duplicates the IRF stay. 2. Request UHC's IRF coverage policy and the InterQual or MCG clinical criteria used — you have the right to these under ERISA §503. 3. Document why IRF-level intensity is medically distinct from and non-duplicative of any other service the patient is receiving. 4. File the internal appeal. If denied, file for external review immediately.

## Documentation to Gather

• Treating physician certification: The admitting physician's IRF order and certification stating the patient requires and can tolerate the intensive, multi-disciplinary therapy regimen, and that this level of care is not duplicated by any concurrent service.
• Functional assessment: Therapy evaluations documenting the specific deficits requiring IRF-level intervention — physical, occupational, and speech therapy assessments with functional goals.
• Distinction from any prior setting: If the patient was in a SNF or received outpatient therapy, documentation showing why that level was insufficient and how IRF differs in clinical intensity.
• Discharge summary from acute stay: Demonstrating the acute medical event that created the rehabilitation need.

## Criteria-Mapping Structure

Obtain UHC's IRF coverage policy criteria and list each requirement. For each criterion — including intensity of service requirements, therapy hours, physician oversight, and medical complexity — match the exact documentation from the patient's chart. Duplicate-therapy denials for IRF are frequently overturned at external review because IRF is a legally and clinically distinct level of care with its own CMS certification requirements.
