Non-prs chr ulcer of neck with muscle invl w/o evd of necr

This code signifies a persistent, non-pressure-related open sore on the neck that extends into the muscle tissue but does not show signs of dead tissue. It indicates a deep ulceration affecting the muscular layer without the presence of necrosis.

Apply this code when documentation specifies a chronic, non-decubitus ulcer located on the neck, with a documented depth reaching the muscle. The absence of necrosis must also be explicitly stated in the medical record. This code is appropriate for ulcers caused by conditions other than sustained pressure.

• Ensure documentation clearly differentiates between muscle involvement and bone involvement; separate codes exist for deeper ulcers.
• Verify the absence of necrosis; if necrosis is present, a different code from the L98.45x series would be appropriate.
• Always code the underlying cause of the ulcer (e.g., diabetes, venous insufficiency) as an additional diagnosis.
