Unspecified open wound of unspecified buttock, sequela

This code indicates a long-term complication or late effect stemming from an open wound on an unspecified area of the buttock. The original wound's specific nature (e.g., laceration, puncture) and the exact buttock region are not documented or are unknown. This sequela code is used when the initial injury has healed, but residual effects persist.

Apply this code when a patient presents with a current condition or symptom that is a direct consequence of a previously sustained open wound to the buttock, and the specific details of the original wound or its precise location on the buttock are not specified in the medical record. This is appropriate for conditions like scar contractures, chronic pain, or nerve damage resulting from the old injury.

• Always assign a sequela code (ending in 'S') as a secondary diagnosis, following the code for the current condition or symptom.
• Ensure documentation clearly links the current condition to a healed open wound of the buttock.
• Avoid using this code if the open wound is still active or undergoing acute treatment; in such cases, an acute injury code would be more appropriate.
