Chronic sphenoidal sinusitis

This code identifies a persistent, long-term inflammation of the sphenoid sinuses, which are located deep within the skull behind the eyes. Chronic sphenoidal sinusitis is characterized by symptoms lasting 12 weeks or longer, often including headache, facial pain, postnasal drip, and nasal congestion.

Assign this code when documentation explicitly states a diagnosis of chronic sphenoidal sinusitis. This typically applies to patients presenting with prolonged symptoms localized to the sphenoid sinus, confirmed by imaging studies such as CT or MRI, and/or endoscopic examination.

• Ensure documentation specifies "chronic" to differentiate from acute sphenoidal sinusitis (J01.30).
• Look for laterality if specified (e.g., unilateral or bilateral), though J32.3 does not differentiate.
• Code any associated complications, such as mucocele or osteomyelitis, separately.
