Open bite of larynx, sequela

This code describes a long-term complication or late effect resulting from an open wound to the larynx. This could include chronic scarring, vocal cord dysfunction, or persistent airway issues that developed after the initial injury. The "sequela" indicates that the acute injury has healed, but its lasting effects are still present.

Apply this code when documentation clearly indicates a current condition or symptom directly attributable to a past open bite injury of the larynx. This is appropriate for follow-up encounters addressing chronic issues stemming from the original trauma, not for the initial acute injury. Documentation should specify the causal link between the past bite and the current laryngeal sequela.

• Always sequence the sequela code first, followed by codes for the specific manifestation(s) of the sequela (e.g., chronic laryngeal stenosis).
• Ensure documentation explicitly states the injury is an "open bite" and specifies the "larynx" as the anatomical site.
• Do not use this code for acute open bite injuries; instead, use the appropriate acute injury code from the S11 category.
