Panniculitis affecting regions of neck/bk, lumbosacr region

This code signifies inflammation of the subcutaneous fat (panniculitis) specifically located in the lower back, encompassing the lumbar and sacral areas. It describes a localized inflammatory process affecting the adipose tissue beneath the skin in this particular anatomical region.

Use this code when documentation clearly indicates panniculitis affecting the lumbosacral region of the back. Supporting documentation would include physician notes detailing the diagnosis of panniculitis and specifying its location as the lower back, lumbar, or sacral area.

• Ensure the documentation explicitly states "lumbosacral region" or a combination of lumbar and sacral involvement for accurate coding.
• Differentiate from other specified sites of panniculitis (e.g., M54.01 for head/neck, M54.02 for cervical region) to avoid miscoding.
• If the underlying cause of the panniculitis is known (e.g., infection, autoimmune disease), code the underlying condition first, followed by this code.
