Chronic tonsillitis and adenoiditis

This code signifies persistent inflammation of both the tonsils and adenoids. It indicates a long-standing condition characterized by recurrent or continuous infection and enlargement of these lymphatic tissues in the pharynx.

Apply this code when documentation clearly indicates a chronic inflammatory process affecting both the tonsils and adenoids. This typically involves a history of recurrent infections, persistent enlargement, or symptoms such as chronic sore throat, difficulty swallowing, or nasal obstruction.

• Differentiate from acute tonsillitis (J03.-) or acute adenoiditis (J03.80) which are sudden onset conditions.
• Ensure the medical record explicitly states "chronic" for both tonsillitis and adenoiditis to support this combined code.
• Consider additional codes for any associated complications, such as obstructive sleep apnea (G47.33) if documented.
