Code is covered without prior authorization (high confidence)
Documentation Required
If billing using ICD-10 codes listed as 'covered if selection criteria are met', documentation must support that the patient meets the selection criteria referenced in the policy (see above).
ICD-10 diagnosis coding consistent with covered codes (e.g., I69.051-I69.059; I69.151-I69.159; I69.251-I69.259; I69.351-I69.359; I69.851-I69.859; I69.951-I69.959; I69.331-I69.339) should be present when selection criteria are met (policy lists these codes as covered if selection criteria are met).
Document baseline and post-treatment objective measures of motor function (examples cited: Action Research Arm Test (ARAT), Nine Hole Peg Test, Fugl-Meyer Assessment (FMA), Motor Activity Log (MAL), Assisting Hand Assessment (AHA), Quality of Upper Extremity Skills Test (QUEST), Wolf Motor Function Test (WMFT), Pediatric Motor Activity Log-Revised (PMAL-R), Melbourne Assessment of Unilateral Upper Limb Function (MUUL), 9-Hole Peg Test, hand grip strength, Box & Block Test).
Key Coverage Criteria
Multiple sclerosis with chronic upper extremity hemiparesis (pilot and phase II trials reported benefit).
Constraint-induced movement therapy (CIMT) is considered medically necessary for the treatment of upper limb hemiparesis in persons with stroke who have at least 10 degrees of active wrist and finger extension, and who have no sensory and cognitive deficits.
Pediatric hemiplegia from causes including perinatal stroke, traumatic brain injury, brachial plexus birth injury (BPBI / OBPP / PBPP), and brain tumors (pilot/feasibility studies reported).
Lower extremity CIMT approaches for lower limb hemiparesis/impairment (stroke, MS — preliminary/lower extremity studies).
Use as an adjunct to other interventions (e.g., paired with peripheral nerve stimulation (PNS), transcranial direct current stimulation (tDCS), repetitive transcranial magnetic stimulation (rTMS), biofeedback, electroacupuncture) to augment motor recovery (pilot and early clinical trials reported).
Stroke (ischemic and unspecified): constraint-induced movement therapy (CIMT) for improving upper extremity function (acute, subacute and chronic stroke populations referenced throughout citations)
Ask Verity about documentation requirements, denial risks, or coverage in your state.
Document patient selection criteria when applicable: e.g., "cognitively intact, medically stable, and able to extend the wrist and 3 fingers 10°" (Brunner et al), and/or "20 degrees of wrist extension and 10 degrees of finger extension, who have no sensory and cognitive deficits" (Veterans Health Administration guideline).
For aphasia/CIAT: document formal language evaluation and outcome measures used (examples cited: Aachen Aphasia Test, Communicative Activity Log, Western Aphasia Battery-Revised, mini-Communication Activity Log), therapy intensity and duration (hours/day, number of days), and pre/post language testing.
Document therapy protocol elements: type of constraint (mitt/glove, sling, casting), restraint duration (hours/day), therapy intensity (hours/day and total hours), duration of treatment block (e.g., 2–3 weeks typical, examples of 2 weeks, 3 weeks, 10 weeks in various studies), and whether a transfer package/behavioral techniques were used.
