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

This code signifies a persistent open sore on the right ankle that is not caused by pressure and extends into the bone. The ulcer shows no signs of dead tissue. This condition often arises from underlying vascular insufficiency, neuropathy, or trauma, leading to impaired healing.

Apply this code when documentation clearly indicates a chronic, non-pressure ulcer located specifically on the right ankle, with confirmed involvement of the underlying bone. Supporting documentation should include imaging reports (e.g., X-ray, MRI) confirming bone involvement and a physician's note specifying the absence of necrosis.

• Ensure laterality (right ankle) is explicitly documented.
• Verify bone involvement is present and documented, distinguishing it from ulcers limited to skin or subcutaneous tissue.
• Confirm the absence of necrosis; if necrosis is present, a different code would be appropriate.
