Check for Scope With Tonsil Biopsy

Question: How should I report a punch excisional biopsy of the left tonsil?

Answer: No specific code exists for a biopsy of the tonsils.

You should instead report the code based on whether the otolaryngologist used a scope. If he didn't, you should assign 42800 (Biopsy; oropharynx).

If the physician used an endoscope, you should report  31535 (Laryngoscopy, direct, operative, with biopsy) or 31536 (... with operating microscope). 

Note: CPT classifies "indirect" laryngoscopy as an endoscopy, even though the procedure requires a mirror, not an endoscope.
