A patient with a diagnosis of chronic sphenoidal sinusitis undergoes a bilateral sinusotomy. While the provider examines the diseased sphenoid sinus, she takes a biopsy of the sphenoid masses and removes the mucosa with several polyps. Transseptal sutures are placed and the intraoral incision is closed in a single layer. The nose is packed and external nasal dressings are placed. What cpt® and icd-10-cm codes are reported?
