Open bite of other part of head, sequela

This code signifies a long-term complication or late effect resulting from an open bite wound to any part of the head not specifically categorized elsewhere (e.g., scalp, forehead, temple). It indicates that the initial injury has healed, but residual issues persist.

Apply this code when documentation clearly indicates a sequela (e.g., scar, chronic pain, nerve damage, disfigurement) directly attributable to a previous open bite of an unspecified head region. The patient's medical record should specify the nature of the sequela and its causal link to the old injury.

• Always sequence the sequela code first, followed by a code describing the specific nature of the sequela (e.g., scar, chronic pain).
• Ensure documentation explicitly states "sequela" or describes a chronic condition resulting from a past injury.
• Distinguish from acute open bites (S01.85XA, S01.85XD) which are used for current injuries.
