Non-prs chronic ulcer of unsp hand with necrosis of bone

This code describes a long-standing open sore on any part of the hand, excluding those caused by pressure. The ulceration has progressed to involve the underlying bone tissue, indicating significant tissue destruction. This condition is characterized by persistent tissue breakdown and impaired healing.

Use this code when documentation specifies a chronic, non-pressure ulcer located on an unspecified hand, and explicitly states the presence of bone necrosis. This typically applies to ulcers resulting from conditions like peripheral vascular disease, diabetes, or autoimmune disorders, where the infection or tissue damage has extended to the bone.

• Ensure the documentation clearly distinguishes between pressure and non-pressure ulcers.
• Verify that "unspecified hand" is appropriate; if a specific hand (right or left) is documented, a more specific code should be used.
• Confirm the presence of bone necrosis; codes for ulcers with necrosis limited to muscle, fascia, or subcutaneous tissue are distinct.
