Panniculitis aff regions of neck/bk, cervicothor region

This code identifies inflammation of the subcutaneous fat (panniculitis) specifically located in the cervicothoracic region, encompassing the neck and upper back. This condition is characterized by tender nodules or plaques within the fat layer.

Apply this code when documentation clearly indicates panniculitis affecting the neck and/or upper back. Supporting documentation should specify the anatomical location of the inflammation, distinguishing it from other body regions.

• Ensure the documentation explicitly states "cervicothoracic region" or "neck and back" to support this specific anatomical site.
• Differentiate from other panniculitis codes based on the affected body region (e.g., M54.01 for head, M54.04 for thoracolumbar).
• Look for underlying causes of panniculitis, which may require additional codes.
