Mechanical Stretching Devices – Commercial and Individual Exchange Medical Policyopen_in_new

UnitedHealthcare covers low-load prolonged-duration stretch (LLPS/dynamic splinting) devices as an adjunct to therapy for existing joint contractures of the upper and lower extremities—particularly finger, wrist, elbow, knee, and toe—and allows custom dynamic splints when prefabricated units are inadequate; static progressive stretch (SPS) and patient‑actuated serial stretch (PASS) devices are considered unproven and not medically necessary. Medical-record documentation may be requested to confirm clinical criteria, coverage is determined by the member’s specific benefit plan and is not guaranteed, and evidence is insufficient for use in other joints, chronic stiffness, or chronic conditions (e.g., RA, cerebral palsy).
