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

This code signifies a persistent, non-pressure-related open sore on the right hand that extends into the muscle tissue. Crucially, there is no indication of tissue death or necrosis associated with this ulcer.

Apply this code when documentation clearly states a chronic ulcer on the right hand, explicitly noting muscle involvement without any mention of necrosis. This is appropriate for conditions like venous stasis ulcers, arterial ulcers, or neuropathic ulcers affecting the hand, provided they meet the depth and chronicity criteria.

• Ensure documentation specifies "right hand" and "muscle involvement" without any mention of necrosis.
• Distinguish from pressure ulcers (L89.-) and acute ulcers, which would use different codes.
• Always look for underlying causes (e.g., diabetes, vascular disease) and code them as secondary diagnoses.
