Unspecified open wound of left buttock, subsequent encounter

This code signifies an open wound on the left buttock where the specific nature of the wound (e.g., laceration, puncture, avulsion) is not documented. The "subsequent encounter" indicator specifies that this code is used for follow-up care after the initial treatment of the injury.

This code is appropriate for encounters where a patient is receiving ongoing care for an open wound on their left buttock, and the initial treatment has already been rendered. This includes wound checks, dressing changes, or monitoring for healing or complications in the absence of a more specific wound type being documented.

• Ensure documentation clearly states "left buttock" and that the wound type is truly unspecified.
• The "D" seventh character indicates subsequent care; use "A" for initial encounters and "S" for sequela.
• Always look for more specific documentation regarding the wound type (e.g., laceration, puncture) before resorting to an "unspecified" code.
