Unspecified open wound of scalp, sequela

This code signifies an open wound on the scalp that is not further specified as to its exact nature (e.g., laceration, puncture) and is a residual effect or complication of an earlier injury. It indicates that the acute phase of the original scalp wound has passed, and the current clinical presentation is a long-term consequence.

Use this code when documentation clearly states an unspecified open wound of the scalp as a sequela, meaning it's a late effect of a previous injury. This applies when the original wound has healed but has left a persistent open area or complication, and the specific type of open wound is not detailed.

• Always sequence a sequela code after the code for the specific sequela (e.g., scar, non-healing wound).
• Ensure documentation explicitly states "sequela" or "late effect" and that the wound is unspecified.
• Avoid using this code for acute open wounds; instead, use the appropriate acute open wound code for the scalp.
