Acute recurrent sphenoidal sinusitis

This code signifies an acute inflammatory process affecting the sphenoid sinuses that recurs after a period of resolution. It indicates a pattern of acute sphenoidal sinusitis episodes rather than a single, isolated occurrence.

Use this code when documentation clearly states "acute recurrent sphenoidal sinusitis" or describes multiple distinct acute sphenoidal sinus infections. Supporting documentation should include physician notes detailing the acute nature of the current episode and a history of prior acute sphenoidal sinusitis.

• Ensure the documentation specifies "recurrent" and not just "acute" or "chronic" sphenoidal sinusitis.
• Distinguish from chronic sphenoidal sinusitis (J32.3), which implies persistent inflammation rather than recurring acute episodes.
• Do not use if the sinusitis is described as acute on chronic; a different code would be more appropriate.
