Sinus barotrauma, sequela

This code signifies the long-term or residual effects of sinus barotrauma, which is damage to the paranasal sinuses caused by pressure changes. These sequelae can include chronic sinusitis, persistent pain, mucosal thickening, or other lasting structural or functional impairments resulting from an acute barotraumatic event.

Apply this code when documenting conditions that are a direct consequence of a past episode of sinus barotrauma, such as chronic sinus pain or recurrent infections clearly linked to a previous pressure injury. It is appropriate for patients presenting with ongoing symptoms or complications after the acute phase of barotrauma has resolved.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic sinusitis).
• Ensure documentation clearly links the current condition to a prior episode of sinus barotrauma.
• Do not use for acute sinus barotrauma; this code is exclusively for the late effects.
