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

This code signifies a persistent open sore on the left ankle that is not caused by pressure. The ulceration extends deeply enough to involve the underlying bone, but there is no indication of dead tissue (necrosis) within the wound.

This code is appropriate for patients presenting with a chronic, non-healing ulcer on the left ankle where imaging or surgical findings confirm bone involvement. Documentation must explicitly state the absence of necrosis and specify the left ankle location.

• Ensure documentation clearly differentiates between pressure and non-pressure ulcers.
• Verify that the medical record explicitly states "bone involvement" and "without evidence of necrosis."
• Do not use this code if necrosis is present; a different code from the L97 series would be more appropriate.
