Non-prs chr ulcer of r forearm with msl invl w/o evd of necr

This code signifies a persistent, non-pressure-related open sore on the right forearm that extends into the muscle tissue. Crucially, there is no indication of dead tissue (necrosis) within the ulcer bed. This condition often results from underlying vascular insufficiency, trauma, or systemic diseases.

Use this code when documentation clearly indicates a chronic ulcer on the patient's right forearm, explicitly stating involvement of the muscle layer. The medical record must also confirm the absence of necrosis. This code is appropriate for ulcers that are not caused by sustained pressure.

• Ensure documentation specifies "right forearm" and "muscle involvement" to differentiate from other anatomical sites or tissue depths.
• Verify the absence of necrosis; if present, a different code indicating necrosis would be required.
• Always code the underlying cause of the ulcer (e.g., chronic venous insufficiency, atherosclerosis) as a primary or secondary diagnosis.
