Coverage Summary

This policy addresses coverage for constraint-induced movement therapy (CIMT) (also called forced use movement therapy) across commercial and Medicare Advantage products and states the insurer's coverage stance. CIMT is an intensive physical therapy approach developed to overcome learned nonuse after central nervous system injury by constraining the less-impaired limb and providing intensive practice with the impaired limb. The evidence summary indicates that methods and outcomes are inconsistent and insufficient to demonstrate clinically useful techniques or improvement in net health outcome.

Coverage Determination

Constraint-induced movement therapy coverage determination:

ALL of the following

Constraint-induced movement therapy is not covered for any indication
Considered not medically necessary for any indication due to insufficient evidence of improvement in net health outcome

Not Covered / Experimental

Constraint-induced movement therapy is not covered for any indication because the evidence is insufficient to determine that the technology results in an improvement in the net health outcome. A Provider Update (May 2024) published this policy; the header indicates no clinical policy statement changes were made.

This position is consistent with the brief's material-change status indicating no material change to clinical policy.

Multiple case studies and a small number of randomized or controlled clinical trials have reported functional gains after CIMT, but systematic reviews (including Cochrane and other reviews) and randomized trials show inconsistent methods and outcomes. Because trial methods, protocols, and outcome measures vary widely, the evidence is insufficient and inconsistent to establish which techniques, if any, are clinically useful.

Billing Rule

Use unlisted PM&R code

There are no specific CPT codes for CIMT; if reporting the service, use unlisted physical medicine/rehabilitation code CPT 97799. Note that constraint-induced movement therapy is not covered for any indication per policy (service considered not medically necessary).

Documentation Required

Benefit determination reference

Verify member-specific benefits and coverage in the member’s Benefit Booklet, Evidence of Coverage, or Subscriber Agreement, as benefits may vary by contract and those documents govern coverage determinations.

Background and Definitions

CIMT includes three core elements: (1) constraining the less-impaired upper extremity; (2) intensive, repetitive daily therapist-directed practice of the impaired extremity typically over an extended period (commonly 2–3 weeks); and (3) shaping of more complex action patterns by rewarding successive approximations to target actions. Protocols vary widely in constraint type, intensity, duration, and outcome measures. Because of this variability and inconsistent trial methods and outcomes, high-quality research is required to identify optimal treatment protocols and to determine clinical benefit. There are no specific procedure codes for CIMT; report using CPT 97799 if reporting.

Term	Definition
Constraint-induced movement therapy (CIMT)
An intensive physical therapy approach including constraining the less-impaired upper extremity, intensive daily therapist-directed practice of the impaired extremity (typically 2-3 weeks), and shaping of action patterns.

Evidence Summary

The evidence base includes numerous case studies and a small number of randomized or controlled clinical trials, as well as systematic reviews and meta-analyses (including Cochrane and other published reviews). These sources report variable results and use heterogeneous methods, preventing clear conclusions about efficacy. Systematic reviews and RCTs have not consistently demonstrated clinically meaningful improvements in net health outcome; therefore the overall evidence is judged inconsistent and insufficient to support coverage.
