Does 42825 Involve Sutures?

Question: Our otolaryngologist performed a tonsillectomy and a primary closure of a tonsillar fossae. Should I bill for the closure or just the tonsillectomy? The diagnoses are chronic tonsillitis and sleep apnea.

Answer: The otolaryngologist may opt to suture the tonsillar pillars after tonsillectomy or to leave them open for healing. You should include the closure in the tonsillectomy code, such as 42825 (Tonsillectomy, primary or secondary; younger than age 12) with both ICD-10 codes for the diagnoses that you indicate: J35.01 (Chronic tonsillitis) and G47.33 (Obstructive sleep apnea (adult) (pediatric)).

Closure has typically not been part of the procedure, but some surgeons believe that closing the tonsillar fossa is a useful procedure for reducing postoperative pain.
