Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Coverage Criteria for IRF Admission and Stay

Medical necessity criteria for IRF admission

Covered when ALL of the following are met

Active participation and expected benefit: Patient can reasonably be expected to actively participate in, and will significantly benefit from, an intensive inpatient rehabilitation program at the time of admission.

Multiple therapy disciplines: Active and ongoing therapeutic intervention of multiple therapy disciplines, one of which must be physical or occupational therapy; may include speech-language pathology and prosthetics/orthotics.

Intensity of therapy: Patient requires an intensive rehabilitation therapy program generally consisting of at least 3 hours per day for at least 5 days per week, or at least 15 hours within a 7 consecutive day period (exceptions allowed if medically necessary).>= 15 hours/week or >=3 hours/day x5 days

Therapy evaluations count toward intensity and required treatments must begin within 36 hours of admission.

Physician supervision: Patient requires physician supervision by a rehabilitation physician with specialized training and experience, documented by at least 3 face-to-face visits per week (one may be by an appropriately trained non-physician practitioner starting the second week).>= 3 visits/week

Visits must be documented in the IRF medical record.

Interdisciplinary team approach: Patient requires an intensive and coordinated interdisciplinary approach; periodic team conferences at least once per week with minimum participation from a rehabilitation physician, rehabilitation nurse, social worker or case manager, and licensed/certified therapists from each involved discipline.

Documentation requirements: Preadmission screening within 48 hours before admission (or acceptable alternative with review), post-admission physician evaluation, overall plan of care completed within first 4 days, admission orders by a physician, and IRF-PAI forms must be included in the record.

Medical necessity and documentation criteria

Covered when ALL of the following are met

Admission medical necessity and documentation: There is a reasonable expectation at time of admission that the patient's medical management and rehabilitation needs require an inpatient stay and close physician involvement, documented in the IRF medical record.

Physician supervision: A rehabilitation physician (or other licensed treating physician with specialized rehabilitation training/experience) must have documented face-to-face visits at least 3 times per week and provide supervision of care.>=3 visits per week

Interdisciplinary team involvement: An interdisciplinary team must manage care with periodic team conferences at least once per week including participation from a rehabilitation physician, a registered nurse with rehab experience, a social worker or case manager, and licensed/certified therapists for each therapy discipline involved.>=1 team conference per week; minimum disciplines listed

An inpatient rehabilitation facility (IRF) is distinguished from less intensive post-acute settings by the high level of physician supervision and an expectation of intensive, interdisciplinary rehabilitation. An IRF admission will not be covered when the patient’s condition can be appropriately and safely managed in a less intensive setting (for example, a skilled nursing facility or outpatient facility) and does not require the complex medical management, frequent physician involvement, or coordinated interdisciplinary services characteristic of an IRF stay.

Trial IRF admissions of approximately 3 to 10 days that are used solely to assess whether a patient might benefit from IRF care are not considered reasonable and necessary. The determination of anticipated benefit must be established through an adequate preadmission screening rather than a short trial admission.

A dated, timed, and authenticated post-admission physician evaluation performed by a rehabilitation physician must be completed within 24 hours of admission and retained in the IRF medical record. If that evaluation does not document and support the continued medical necessity of IRF services, the facility must begin the discharge process immediately.

Admissions that do not require the high level of physician supervision or the coordinated interdisciplinary care that define IRF services are not covered. Examples include patients whose medical needs can be met safely in a lower-intensity setting (such as a SNF or outpatient program) and patients without complex or unstable medical conditions requiring frequent physician intervention.

If the post-admission physician evaluation fails to support continued IRF-level care, services provided beyond the third day following admission will not be considered reasonable and necessary. In that situation the IRF must initiate discharge and the stay will be treated as appropriate for an IRF length of 3 days or less.

Coding, Intensity & Key Clinical Thresholds

CODINGmixed

No codes listed

inv-09: BMI threshold

BMI thresholdBody mass index (BMI) ≥ 50 at time of IRF admission

ContextExtremely obese patients (BMI ≥ 50) identified as more likely to require IRF level of care

Source useUsed as one example of characteristics that add complexity warranting IRF admission

inv-10: Therapy intensity

Therapy intensity standard>= 15 hours per week (accepted standard) OR >= 3 hours per day for at least 5 days per week, or at least 15 hours within a consecutive 7-day period

Evaluations countTherapy evaluations count toward intensity and required treatments must begin within 36 hours of admission

ExceptionsExceptions to exact timing or intensity allowed if medically necessary (brief interruptions ≤ 3 consecutive days permitted)

inv-11: Post-admission evaluation timeframe

TimeframePost-admission physician evaluation must be performed and completed within the first 24 hours after admission to the IRF

PerformerMust be performed by a rehabilitation physician (a resident or physician extender may complete H&P but rehabilitation physician must complete remaining parts and visit the patient)

ContentEvaluation must include dated, timed, authenticated H&P, review of prior/current conditions and comorbidities, and identification of changes since preadmission screening

Provider Requirements, Authorization & Documentation

Prior Authorization

Prior Authorization Required

Prior authorization is required for Medicare Advantage plans and is recommended for Commercial products. Lack of prior authorization may lead to noncoverage or denial depending on the member's product benefit terms. Providers should verify benefit-specific prior authorization requirements before admission and obtain any required authorizations according to BCBSRI procedures.

Medicare Advantage: prior authorization required
Commercial: prior authorization recommended; benefit-dependent

Documentation Required

Post‑Admission Physician Evaluation Requirement

A dated, timed, and authenticated post-admission physician evaluation must be completed by a rehabilitation physician within 24 hours of IRF admission. The evaluation must document history and physical exam, review prior and current medical and functional conditions and comorbidities, identify changes since preadmission screening, and support the medical necessity of the IRF admission. If a resident or physician extender completes the H&P, the rehabilitation physician must still complete the remainder of the required evaluation elements and visit the patient.

Completed within 24 hours of admission
Performed by a rehabilitation physician (H&P may be done by resident/physician extender with physician follow-up)
Must support medical necessity of the IRF admission

Denial Risk

Discharge Initiation When Post‑Admission Evaluation Not Supportive

If the post-admission physician evaluation does not support continued appropriateness of IRF services, the IRF must begin the discharge process immediately. Services beyond the third day will not be considered reasonable and necessary if the evaluation is not supportive; payment will be at the appropriate rate for IRF stays of three days or less.

Begin step‑down/discharge immediately when evaluation is not supportive
Services after day 3 not reasonable/necessary if evaluation fails to support ongoing IRF care

Documentation Required

Required Documentation for IRF Admissions (Preadmission Screening)

Required documentation for IRF admissions includes a thorough preadmission screening completed within 48 hours prior to admission (in person or by telephone with review of referring hospital records when applicable). The preadmission screening must document prior level of function, expected level of improvement and anticipated length of time, evaluation of risk for clinical complications, conditions causing need for rehabilitation, treatments needed, anticipated discharge destination, expected frequency and duration of treatments, anticipated post‑discharge treatments, and any other relevant information. Telephone‑only screenings require transmission and review of referring hospital medical records by IRF clinical staff.

Preadmission screening within 48 hours prior to admission (required elements listed)
Telephone‑only screening acceptable only with hospital records transmitted and reviewed

Documentation Required

Required Documentation for IRF Stay

Documentation required during the IRF stay includes the overall plan of care (completed within the first 4 days) detailing medical prognosis, anticipated interventions, expected intensity (hours/day), frequency (sessions/week), and duration (total expected IRF days) for each therapy discipline; physician admission orders; completed IRF‑PAI forms corresponding to the medical record; and evidence of close physician involvement (rehabilitation physician face‑to‑face visits at least 3 times per week) and interdisciplinary team participation with weekly conferences. Any significant deviations from the plan of care must be thoroughly documented.

Overall plan of care completed within first 4 days and retained in medical record
Physician admission orders documented at time of admission
IRF‑PAI forms included and consistent with the record
Rehabilitation physician face‑to‑face visits at least 3 times/week documented
Weekly interdisciplinary team conferences and documentation

Note

Prior Authorization Expectations and Benefit Variability

Prior authorization expectations may vary by product. For Medicare Advantage enrollees, prior authorization is required; for Commercial products, prior authorization is recommended but coverage decisions depend on the specific benefit design. Admissions without prior authorization may be subject to noncoverage or retrospective denial if the product requires authorization.

Verify product‑specific prior authorization rules
Unapproved admissions may be denied depending on benefit terms
