Coverage Criteria — Inpatient Rehabilitation Facility (IRF)
Medical necessity for IRF admission
Covered when ALL of the following are met
Clinical review judgment applies; individual circumstances may justify variations in therapy timing and intensity. Preadmission screening should occur within 48 hours and must document risk for complications, prior function, expected improvement and anticipated discharge.
Admission and ongoing IRF medical necessity
Covered when ALL of the following are met
Interdisciplinary team requirement
- Minimum disciplines: Must include: (a) a rehabilitation physician with specialized training and experience; (b) a registered nurse with rehabilitation experience; (c) a social worker or case manager (or both); (d) a licensed or certified therapist from each therapy discipline involved in treating the patient.4 listed roles
Each participant must have current knowledge of the patient documented in the record.
A resident or physician extender may complete the H&P component but the rehabilitation physician must still visit and complete the other required parts. The post-admission evaluation does not count as one of the three required rehabilitation physician face-to-face visits in the first week.
If the post-admission physician evaluation does not support continued IRF services, begin discharge immediately; services after day 3 will not be considered reasonable and necessary.
An IRF stay is not covered when the patient's clinical condition can be appropriately managed in a less intensive setting. Specifically, coverage is denied if the patient’s needs can be met in a skilled nursing facility (SNF) or outpatient setting rather than an inpatient rehabilitation facility. Documentation should demonstrate why the patient requires inpatient-level resources, including the need for intensive interdisciplinary care and frequent physician supervision; absence of that documentation may place the stay outside covered IRF criteria.
A dated, timed, and authenticated post-admission physician evaluation performed by a rehabilitation physician must be completed within the first 24 hours of admission and must support medical necessity for continued IRF care. If that evaluation does not support continued appropriateness of IRF services, the facility must initiate discharge immediately; services after the 3rd day will not be considered reasonable and necessary.
Admissions that are intended as short 'trial' stays of approximately 3–10 days to determine potential benefit from IRF-level care are not considered reasonable and necessary. Determination of appropriateness must be made during the preadmission screening process prior to admission rather than by admitting the patient for an observation trial.
If the post-admission physician evaluation does not substantiate the need for continued IRF services, the IRF must begin the discharge process immediately. Continued inpatient services beyond day 3 will not be covered, and payment will be adjusted to reflect an IRF stay of 3 days or less.
Denial risk: incomplete documentation of IRF medical necessity
Failure to document that the patient meets IRF medical necessity criteria — including evidence of need for an intensive therapy program, an interdisciplinary team, and rehabilitation physician supervision — or failure to complete or update the required preadmission screening within 48 hours may result in denial of coverage. Ensure the medical record contains the preadmission screening (or an update within 48 hours), documentation of multiple therapy disciplines and expected frequency/duration, and physician supervision details (rehab physician with ≥3 face-to-face visits/week). If the post-admission physician evaluation does not support continued IRF services, discharge must be initiated immediately; services after day 3 will not be considered reasonable and necessary.
- Preadmission screening completed by licensed/certified clinician(s) within 48 hours before admission, or an update within 48 hours if initial screening was earlier [[chunk 8]].
- Preadmission screening must document prior level of function, expected improvement and time to achieve it, evaluation of risk for clinical complications, treatments needed, and expected frequency/duration of therapy [[chunk 8]].
- Document need for active and ongoing therapeutic intervention of multiple therapy disciplines (one must be PT or OT) and an intensive rehabilitation therapy program (generally ≥3 hours/day × 5 days/week or 15 hours/7 days) [[chunk 2]].
- Document rehabilitation physician supervision (rehab physician with at least 3 face-to-face visits per week) and a dated, timed, authenticated post-admission physician evaluation within 24 hours that supports continued IRF medical necessity; if that evaluation does not support continued IRF care, begin discharge immediately and services after day 3 will not be considered reasonable and necessary [[chunk 3]][[chunk 21]].

Discharge Criteria and When to Transition Care
Discharge from an IRF is appropriate when the overall plan of care and team assessment show that rehabilitation goals have been achieved or are no longer achievable in the IRF, or when the patient's condition can be managed safely in a less intensive setting. Discharge decisions must be documented in the weekly interdisciplinary team conference notes, which must record participants and the rehabilitation physician's concurrence, and must reflect progress toward measurable functional goals and the plan for safe return to home or the community.
Begin discharge immediately if the post‑admission physician evaluation (completed within 24 hours) does not support continued IRF services; services after the 3rd day will not be considered reasonable and necessary and payment will be adjusted accordingly.
Two situations mandate initiating discharge planning: (1) achievement of the rehabilitation goals documented in the overall plan of care or determination that goals are not achievable in the IRF setting; and (2) a post‑admission physician evaluation that does not support continued IRF care. In both cases the rationale must be documented in the team conference notes, and the focus of discharge planning should be safe return to home or a less intensive setting.
The policy emphasizes that the post‑admission physician evaluation is integral to discharge decisions: it must compare admission status to preadmission screening, include H&P and review of comorbidities, and be completed by a rehabilitation physician within 24 hours—if it fails to support continued inpatient rehabilitation, services beyond the 3rd day are not reasonable and necessary.
Initiate discharge immediately if post-admission evaluation does not support continued IRF care
If the post-admission physician evaluation does not support continued appropriateness of IRF services, begin the discharge process immediately; continued inpatient services beyond the 3rd day will not be considered reasonable and necessary.
- IRF must initiate discharge immediately when post-admission evaluation fails to support continued IRF care.
- Services after day 3 will not be considered reasonable and necessary and payment will be at the rate for stays of 3 days or less.

Provider Actions, Documentation & Prior Authorization
Preauthorization requirement
Preauthorization is required for BlueCHiP for Medicare and is recommended for Commercial products.
- Obtain required preauthorization for BlueCHiP for Medicare prior to IRF admission.
- Consider obtaining preauthorization for Commercial members as recommended.
Post-admission physician evaluation required within 24 hours
A dated, timed, and authenticated post-admission physician evaluation must be performed by a rehabilitation physician and completed within the first 24 hours after admission; it must support the medical necessity of admission and include an H&P and review of prior/current medical and functional conditions.
- Evaluation must be performed by a rehabilitation physician and completed within 24 hours of admission.
- Include H&P (which may be completed by a resident or physician extender) and review of prior and current medical and functional status.
- If a resident or extender completes the H&P, the rehabilitation physician must still visit and complete the other required parts.
No trial IRF admissions (3–10 day observation stays)
Trial IRF admissions (3–10 day observation admissions to assess benefit) are not considered reasonable and necessary; eligibility must be determined by a careful preadmission screening prior to admission.
- Do not admit patients for a short 'trial' IRF stay to assess benefit; complete a thorough preadmission screening instead.
Retain required preadmission screening and related admission documentation
Retain complete preadmission screening documentation that includes prior level of function, expected improvement and timeframe, evaluation of risk for clinical complications, conditions causing need for rehab, treatments needed, and expected frequency/duration of treatment.
- Preadmission screening must be conducted within 48 hours before admission or updated within 48 hours if older.
- Include expected discharge destination and any anticipated post-discharge treatments.
- Ensure IRF-PAI forms, physician admission orders, and evidence that multiple therapy disciplines are required are in the record.
Document weekly interdisciplinary team conferences and rehabilitation plan/progress
Document weekly interdisciplinary team conferences with names and professional designations of participants; document the rehabilitation physician's concurrence with team decisions and retain documentation of the rehabilitation treatment plan and measurable rehabilitation progress.
- Team conferences must occur at least once per week and include required disciplines (rehabilitation physician, registered nurse with rehab experience, social worker or case manager, and licensed therapists involved).
- Document decisions made at conferences (including discharge planning), participants' names and professional designations, and measurable progress toward functional goals.
- Retain the overall plan of care within the first 4 days of admission.
Post-admission evaluation denial risk for continued services after day 3
If the post-admission physician evaluation does not support continued appropriateness of IRF services, services provided after the 3rd day will not be considered reasonable and necessary and may be denied.
- Ensure the post-admission evaluation documents continued medical necessity to avoid denial for services beyond day 3.
Definitions
Background
Inpatient rehabilitation facilities (IRFs) provide intensive, resource‑intensive inpatient rehabilitation for patients with complex medical, nursing, and rehabilitation needs who are expected to actively participate and significantly benefit from an intensive therapy program. IRF care is characterized by a coordinated interdisciplinary team led by a rehabilitation physician, close physician supervision to manage medical complexity, and therapy intensity that cannot be safely or effectively delivered in less intensive settings.
Typical IRF patients have medically complex conditions requiring physician supervision (for example medication adjustments, IV interventions, recognition of acute deterioration, pulmonary rehabilitation, or potential acute transfer). An IRF stay is only reasonable and necessary when the patient's condition, expected improvement, and required interventions justify the intensive interdisciplinary and physician‑led services provided in the IRF.
