Documentation Required

For knee orthoses with adjustable knee joints or prefabricated Swedish type (HCPCS L1832, L1833, L1850) the medical record must document a physical examination of the affected knee(s) including the joint laxity test(s) performed and a description of exam findings that support objective joint laxity.
For single or double upright, adjustable flexion/extension knee orthoses with medial-lateral and rotation control (HCPCS L1843, L1844, L1845, L1846, L1851, L1852) used for ambulatory beneficiaries with knee instability, medical records must document ambulatory status and a physical exam of the affected knee(s) including joint laxity test(s) performed and description of findings supporting objective joint laxity.

For the same single/double upright orthoses (L1843, L1844, L1845, L1846, L1851, L1852) when used to manage pain affecting mobility/function due to medial or lateral tibiofemoral osteoarthritis, records must include ambulatory status; pain symptoms or mobility/functional reduction; physical exam of the affected knee(s); an imaging report describing arthritic changes consistent with medial/lateral tibiofemoral osteoarthritis; and the beneficiary's willingness to use the orthosis.

Supplier must include the treating diagnosis code(s) on the claim line for HCPCS L1830, L1831, L1832, L1833, L1834, L1836, L1840, L1843, L1844, L1845, L1846, L1850, L1851, L1852, and L1860.

For custom-fabricated orthoses the supplier's records must document the medical necessity of a custom device rather than a prefabricated orthosis, and this documentation must be available upon request.

Suppliers must provide the product specified by the treating practitioner, ensure the practitioner's medical record justifies the product type (prefab versus custom), bill only the HCPCS code that accurately reflects the orthosis and fitting level, and maintain detailed supplier documentation that justifies the code selected.

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.
Attended/manual electrical stimulation (CPT 97032) is covered when the qualified professional provides direct 1-on-1 patient contact to apply/manualy adjust stimulation (e.g., direct motor point stimulation, FES/NMES when combined with therapeutic exercise/neuromuscular reeducation/functional activities).
Non-implantable pelvic floor electrical stimulation delivered via vaginal or anal probes (reportable as CPT 97032) is covered for stress and/or urge urinary incontinence in cognitively intact, motivated patients who have failed a documented 4-week trial of pelvic muscle exercise (PME) training.
