Pressure ulcer of left ankle, unstageable

This code signifies a pressure ulcer located on the left ankle that cannot be clinically staged. This means the full extent of tissue damage, particularly the depth, is obscured by slough or eschar, preventing accurate classification into a Stage 1, 2, 3, or 4.

Use this code when documentation clearly indicates a pressure ulcer on the patient's left ankle, and the wound bed is covered by non-viable tissue (e.g., slough, eschar) to an extent that prevents the determination of the ulcer's depth. This code is appropriate when the clinician explicitly states the ulcer is "unstageable" due to this obscuring tissue.

• Ensure the documentation specifies "left ankle" and "unstageable" due to slough/eschar.
• Do not use this code if the ulcer is fully visible and can be staged, even if it's a deep tissue injury.
• Always sequence this code after any underlying conditions contributing to the pressure ulcer, such as immobility or diabetes with complications.
