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

This code describes a persistent open sore on the left ankle that is not caused by pressure and extends into the muscle tissue, but without any dead tissue present. It indicates a significant depth of tissue damage in a non-pressure ulcer.

Use this code when documentation specifies a chronic, non-pressure ulcer located on the left ankle with involvement of the muscle layer. The medical record must explicitly state the absence of necrosis. This code is appropriate for conditions like venous stasis ulcers or arterial ulcers that have progressed to muscle involvement.

• Ensure documentation clearly distinguishes between pressure and non-pressure ulcers.
• Verify the laterality (left ankle) and the specific tissue depth (muscle involvement) are explicitly stated.
• Confirm the absence of necrosis; if necrosis is present, a different code reflecting that condition would be necessary.
