Key Coverage Criteria
- A knee orthosis is covered when it is a rigid or semi-rigid device used to support a weak or deformed knee or to restrict or eliminate motion in a diseased or injured knee and the device meets the reasonable and necessary requirements of the related Local Coverage Determination and all statutory/regulatory requirements.
- Both off-the-shelf (OTS) and custom-fit knee orthoses are treated as prefabricated braces for coding and may be covered provided the coding accurately reflects whether only minimal self-adjustment was required at final fitting per 42 CFR §414.402.
- If the orthosis is provided prior to an inpatient hospital admission or Part A SNF stay and the medical necessity begins during that inpatient stay, payment is included in the hospital or SNF payment (do not submit claim to the DME MAC).
- An orthosis provided within two days prior to discharge and not needed for inpatient treatment but intended for home use is eligible for DME MAC coverage if medically necessary after discharge.
- CPT 97110 may be billed when treating impairments of exercise tolerance due to cardiopulmonary impairments.
- CPT 97542 (wheelchair management training) may be billed for wheelchair propulsion training when the training is tied to expected functional goals attainable by the patient or caregiver.
