Pressure ulcer of other site, stage 3

This code signifies a full-thickness skin and tissue loss due to prolonged pressure, affecting an anatomical location not specified by more granular codes. The ulcer presents as a deep crater with visible subcutaneous fat, but bone, tendon, or muscle are not yet exposed. Slough may be present, but it does not obscure the depth of tissue loss.

Apply this code when documentation clearly indicates a Stage 3 pressure ulcer located on a site other than the back, buttock, hip, or ankle. This includes areas like the ear, scalp, or abdomen. Physician documentation must explicitly state "Stage 3" and the "other site" location.

• Ensure the documentation specifies "Stage 3" and not an unstageable or deep tissue injury.
• Verify the anatomical site is not covered by more specific L89.xx codes (e.g., L89.1xx for back, L89.3xx for buttock).
• Always sequence this code after any underlying condition contributing to the pressure ulcer, such as immobility or malnutrition.
