Unspecified open wound of unspecified part of head, sequela

This code describes the long-term effects or complications arising from an open wound of the head, where the specific location and nature of the wound are not documented. It indicates that the initial injury has healed, but residual issues persist.

Use this code when a patient presents with a sequela (e.g., scar, chronic pain, nerve damage) directly attributable to a past, unspecified open head wound. Documentation should clearly state the sequela and its causal link to a previous open head injury, without specifying the exact anatomical site of the original wound.

• Always attempt to code to a more specific anatomical site and laterality if documented.
• This code requires an additional code to identify the specific sequela (e.g., scar, neurological deficit).
• Ensure documentation explicitly states "sequela" or "late effect" of a previous open head wound.
