Monitor payer policy activity
This policy governs medical necessity, documentation, and coverage criteria for habilitation, rehabilitation, and maintenance outpatient occupational, physical, and speech therapy services for Colorado Rocky Mountain Health Plans members (state-specific exceptions listed). It applies to providers requesting evaluation, ongoing therapy, re-evaluations, group therapy, and feeding/swallowing services.
Updated list of required documentation for a therapy re-evaluation report; replaced 'compliance to home program' with 'adherence to home program'.
Medical Necessity and Coverage Criteria
General Coverage and Medical Necessity
Covered when ALL of the following are met:
InterQual criteria external reference
See documentation module for required elements
Services must not be duplicate services of another type of therapy
Feeding and Swallowing Evaluation Criteria
Feeding/swallowing evaluations are covered when the assessment includes all listed elements:
All elements listed must be submitted
Coverage criteria for OT evaluations, re-evaluations, and maintenance exclusion
Covered when therapy is rehabilitative or habilitative with measurable, achievable goals and when services are restorative rather than maintenance.
Moderate complexity OT evaluation (97166)
High complexity OT evaluation (97167)
Formal re-evaluation triggers revised POC
Maintenance therapy is excluded from rehabilitative coverage
This policy does not apply to cognitive therapy. Outpatient cognitive therapy is governed separately by the Medical Policy titled Cognitive Rehabilitation and Coma Stimulation, so refer to that policy for coverage and documentation requirements when cognitive rehabilitation is the primary service requested.
Maintenance therapy refers to services intended to prevent decline, promote health, or maintain function where further clinical improvement cannot reasonably be expected. When ongoing care is primarily supportive rather than corrective in nature, it is considered maintenance therapy and is distinguished from rehabilitative or habilitative services.
Services are not medically necessary when the skill of a therapist is not required to achieve the desired outcome, when established treatment goals and objectives have been met, or when the individual’s behavior or clinical status prevents participation despite reasonable attempts to address these factors. Inadequate objective progress, or treatment and evaluation documentation that fail to demonstrate the need for skilled therapy (for example, missing history, diagnosis with ICD-10, prognosis, baseline measures, measurable plan of care, or treatment notes that do not match billed CPTs and lack session length, response, skilled reassessment, or provider signature), also may render continued therapy not medically necessary.
Ongoing care that is supportive rather than restorative—where the purpose is to preserve current function rather than to achieve additional measurable improvement—is classified operationally as maintenance therapy. When continuous treatment no longer reasonably yields further clinical gains and instead serves only to maintain function, the service is considered maintenance and is not treated as rehabilitative coverage.

Authorization, Documentation, and Provider Requirements
Prior authorization and referral required for therapy requests
Therapies may be authorized upon clinical review when InterQual Outpatient Rehabilitation criteria and the policy’s documentation requirements are met; typical authorizations are for up to six months. A referring provider order (PCP or appropriate specialist: MD, DO, PA, or NP) must be on file prior to the evaluation unless exempted by state rules.
- Authorization based on InterQual clinical criteria and required documentation
- Typical authorization period up to six months
- Referring provider order required prior to evaluation unless state exempts
Modality services (including wound electrical stimulation) require plan‑of‑care review
Unattended electrical stimulation for chronic non‑healing wounds (G0281) and other unattended modality codes (e.g., G0283) are described as part of a therapy plan of care and may require plan‑level review or authorization per benefit terms.
Provide complete evaluation and POC with authorization requests
Submit complete evaluation and plan‑of‑care documentation with authorization requests; failure to provide required documentation or referring provider order may result in denial. Documentation must demonstrate skilled need, measurable goals, and objective baseline measures.
- Referring provider order on file prior to evaluation (unless state exempts)
- Evaluation must include medical history, comparison of prior and current function, description of functional impairment, clear diagnosis with ICD‑10, prognosis, and baseline objective measurements or task analysis
- POC must include functional short‑ and long‑term measurable time‑based goals, treatment frequency/duration, and anticipated session length
Match treatment notes and continuity documentation to billed services
Ensure treatment notes and continuity documentation match the requested services and billed CPTs; documentation deficiencies are common denial triggers and must be avoided.
- Treatment notes must document date, specific treatments matching billed CPT(s), session length, individual's response, skilled ongoing reassessment, objective progress toward goals, any POC changes, home program involvement, and treating provider signature/date
- Continuation requests must include prior authorized weeks/visits, current status vs baseline with objective measures, and justification for continued skilled services
Required documentation for evaluations, plan of care, continuation, re‑evaluation, and treatment notes
Initial evaluation, plan of care, continuation requests, re‑evaluations, and treatment session notes must include the specified elements: initial evaluation (medical history; prior vs current function; functional impairment impact; ICD‑10 diagnosis; prognosis; baseline objective standardized assessment scores or task‑analysis alternatives); POC (functional impairment, measurable time‑based goals, frequency/duration); continuation (prior authorized visits/weeks, objective status vs baseline); re‑evaluation (updated standardized scores, progress, updated POC ≤90 days old); and treatment notes (date, treatments matching CPT, length, response, skilled reassessment, objective progress, POC changes, home program involvement, signature/date).
- Initial evaluation: medical history; comparison of prior and current function; description of functional impairment; clear diagnosis with ICD‑10; prognosis; baseline objective measurements or task‑analysis alternatives
- POC: functional or physical impairment, functional measurable short‑ and long‑term goals, treatment frequency/duration, anticipated session length
- Continuation requests: prior authorized weeks/visits, current status vs baseline with objective measures, need for continued skilled services
- Treatment notes: date, specific treatments matching CPT(s) billed, session length, individual's response, skilled ongoing reassessment, objective measurable progress, POC changes, home program involvement, signature/date
Document re‑evaluations with specified updated elements
Re‑evaluation reports must document date of last evaluation, number of authorized and attended therapy visits, adherence to home program, objective description of current deficits and severity, objective demonstration of progress toward each goal (baseline and current for unmet goals), updated prescribed modalities with frequency/duration, brief prognosis with discharge criteria, and an updated individualized POC (must not be older than 90 days). Note: terminology in re‑evaluation requirements was updated from 'compliance to home program' to 'adherence to home program'.
- Include date of last therapy evaluation and number of visits authorized/attended
- Document adherence to home program and objective current deficits with severity using standardized scores or equivalent
- Provide objective demonstration of progress toward each treatment goal and updated POC (≤90 days) with discharge criteria and revised plan if goals unmet
Common documentation‑based denial triggers
Denials may be triggered when a referring provider order is absent prior to the evaluation (unless state exempt), or when the evaluation/POC or treatment notes lack required elements such as history, ICD‑10 diagnosis, prognosis, baseline objective measures, measurable POC goals and frequency, or treatment notes that do not match billed CPTs or lack session length, response, skilled reassessment, or signature.
- Missing referring provider order before evaluation (unless state exemption)
- Insufficient evaluation or POC documentation (missing history, diagnosis with ICD‑10, prognosis, baseline objective measures, or missing plan of care with measurable goals and frequency/duration)
- Treatment notes that do not match billed CPTs, lack session length, lack documented response, lack skilled reassessment, or lack treating provider signature/date
Avoid treating services that are maintenance in nature without documented restorative need
Services that are supportive rather than corrective when further clinical improvement cannot reasonably be expected are considered maintenance therapy and may not meet rehabilitative coverage criteria; document restorative intent and measurable progress to mitigate denial risk.
- Maintenance therapy defined as care intended to maintain or prevent deterioration when further clinical improvement is not reasonably expected
- If treatment is supportive rather than corrective and a clinical plateau is reached, services may not meet coverage criteria
Policy Background and Scope
Habilitation, rehabilitation, and maintenance therapies (occupational, physical, and speech) are intended to restore, develop, or preserve functional abilities following illness, injury, congenital condition, or developmental delay. Rehabilitative services aim to improve, adapt, or restore functions with achievable, time‑based goals and therapist‑directed interventions. Habilitation services help individuals learn or regain developmental skills (for example, therapy for a child not meeting expected milestones). Maintenance therapy seeks to prevent decline or maintain current function when further clinical improvement is not reasonably expected. Medical necessity determinations reference the InterQual® Outpatient Rehabilitation & Chiropractic criteria and require appropriate evaluation, baseline objective measures, a plan of care with measurable goals, and treatment documentation demonstrating skilled need and measurable progress.
