Capture 31267 for Sinus Biopsy

Question: An otolaryngologist documented a procedure as: left endoscopic maxillary antrostomy with biopsy, sinus tissue contents. left maxillary sinusoscopy.

On the superbill, the surgeon coded 31256 and wrote as an extra procedure "maxillary sinusoscopy." I think the otolaryngologist is correct not to bill 31267 because he did not remove tissue. But how should I code the sinusoscopy?

Answer: The otolaryngologist actually does deserve credit for 31267 (Nasal/sinus endoscopy, surgical, with maxillary antrostomy; with removal of tissue from maxillary sinus). Because the surgeon takes a biopsy of the maxillary sinus and a biopsy involves taking tissue, the procedure qualifies as 31267. Code 31267 does not require complete tissue removal, just tissue removal.

When the otolaryngologist performs a maxillary antrostomy and doesn't remove any tissue, such as a biopsy or polyp, you should instead assign 31256 (Nasal/sinus endoscopy, surgical, with maxillary antrostomy).

On the other hand, you should not code the sinusoscopy. Surgical endoscopy (such as 31256-31267) includes diagnostic endoscopy (for instance 31233, Nasal/sinus endoscopy, diagnostic with maxillary sinusoscopy [via inferior meatus or canine fossa puncture]).
