What four indications are necessary for a LSO or TLSO to be covered by Medicare?

The correct choice highlights the primary medical reasons for which a lumbar-sacral orthosis (LSO) or thoraco-lumbar-sacral orthosis (TLSO) is deemed medically necessary and thereby eligible for coverage by Medicare.

Support for a broken bone is crucial because LSO and TLSO are often used in the treatment of spinal fractures, providing the necessary immobilization that aids in healing. The facilitation of healing after an injury underscores the orthosis's role in stabilizing the spine and preventing further injury, which is vital in the recovery process.

Reducing pain by restricting motion is another key function of these devices. By limiting movement in specific areas, LSOs and TLSOs help alleviate discomfort associated with various spinal conditions, further contributing to patient recovery and comfort.

Lastly, supporting a weak or deformed spine is integral for patients with conditions like scoliosis or degenerative spine diseases. These orthoses provide structural support to maintain spinal alignment and prevent further deformity, thereby enhancing the patient's quality of life and functionality.

This focus on medical necessity reflects Medicare’s coverage criteria, which prioritize devices that directly address injury treatment, pain management, and structural stability of the spine. Other options provided either address aspects that are not aligned with medical necessity or involve
