Which code refers to the lumbar region?

Explanation:
The important idea is that these M99 codes pin down the exact region of the spine where a segmental or somatic dysfunction is identified. The digits after M99 specify the region, with the lumbar region assigned the code that ends in 03. So M99.03 represents segmental and somatic dysfunction of the lumbar region, which is why it’s the correct choice. The other options designate other regions (cervical, thoracic, or adjacent areas) and do not refer to the lumbar region.
