Non-prs chr ulcer of l up arm with msl invl w/o evd of necr

This code signifies a long-standing ulcer on the patient's left upper arm that is not caused by pressure. The ulcer has progressed to involve the underlying muscle tissue but does not show any signs of dead tissue. This indicates a significant depth of tissue damage.

Use this code when documentation clearly states a chronic, non-pressure ulcer located specifically on the left upper arm. The medical record must also confirm muscle involvement and explicitly state the absence of necrosis. This code is appropriate for ulcers requiring complex wound care due to their depth.

• Ensure the documentation specifies "chronic" and "non-pressure" to differentiate from acute or pressure ulcers.
• Verify the exact anatomical location (left upper arm) and the depth of involvement (muscle) are clearly documented.
• Do not use this code if necrosis is present; a different code reflecting necrosis would be more appropriate.
