Open bite of pharynx and cervical esophagus, sequela

This code signifies a late effect or complication arising from a previous open bite injury to the pharynx and/or cervical esophagus. It indicates a current problem directly attributable to the initial traumatic event, which has since healed but left lasting sequelae. Examples include strictures, fistulas, or chronic pain resulting from the original injury.

Apply this code when documenting a current condition that is a long-term consequence of an open bite to the pharynx or cervical esophagus. The patient's medical record should clearly state the causal link between the past injury and the present sequela. This code is appropriate when the acute phase of the original injury has passed.

• Always sequence the sequela code first, followed by codes for the specific manifestation of the sequela (e.g., esophageal stricture).
• Ensure documentation explicitly links the current condition to a previous open bite of the pharynx or cervical esophagus.
• Do not use this code for acute injuries; instead, refer to the appropriate acute injury codes.
