Unspecified open wound of left buttock, sequela

This code signifies a long-term consequence or late effect stemming from an open wound on the left buttock, where the specific nature of the wound (e.g., laceration, puncture) is not documented. It indicates that the original injury has healed, but residual issues related to that wound persist.

Apply this code when documentation clearly indicates a sequela (e.g., scar tissue, chronic pain, functional impairment) resulting from a previously sustained open wound to the left buttock. This is appropriate when the acute phase of the original injury has passed, and the current encounter addresses these lasting effects.

• Ensure the medical record explicitly states the condition is a "sequela" or "late effect" of a prior open wound.
• Always sequence this code after the code describing the specific nature of the sequela (e.g., scar, chronic pain).
• Avoid using this code for acute open wounds; use the appropriate acute open wound code from the S31 series instead.
