Panniculitis affecting regions of neck/bk, thoracic region

This code signifies inflammation of the subcutaneous fat (panniculitis) specifically located in the thoracic region of the back and neck. It indicates a localized inflammatory process affecting the adipose tissue beneath the skin in this anatomical area.

Use this code when documentation clearly states a diagnosis of panniculitis affecting the thoracic spine, upper back, or neck. Supporting documentation should include a physician's diagnosis and may reference physical exam findings or imaging results confirming the location of the inflammation.

• Ensure the documentation specifies "thoracic region" for the back/neck involvement; otherwise, a more general panniculitis code may be appropriate.
• Distinguish from other inflammatory conditions of the back, such as myositis or fasciitis, which affect muscle or fascia, respectively.
• Always code any underlying cause of the panniculitis (e.g., lupus, infection) as a primary or secondary diagnosis, following sequencing guidelines.
