HCPCS Code L1843

A custom-fabricated device, in this case, custom-fabricated orthoses for the knee, are not available off-the-shelf and are not pre-made. The patient must undergo evaluations for an orthotist to design and create a specific orthosis for the patient based on the results and the patient's needs and measurements.

Since it may need to be trimmed, bent, molded, assembled, or otherwise customized to fit a specific patient, it'll probably take up to an hour.

They must follow what their provider specified for them. They might have to wear it for several weeks to months, depending on the problem being addressed by the orthosis. But they must not wear it for longer than advised each day. Prolonged use may lead to skin irritation and pressure sores.
