Sphenoid sinusotomy with biopsy is reported with code __________.

The code for sphenoid sinusotomy with biopsy is 31050. This procedure involves the surgical opening of the sphenoid sinus for diagnostic or therapeutic purposes, often incorporating the acquisition of tissue for histopathological examination (biopsy).

In the context of CPT coding, 31050 is specifically designated for "Sphenoid sinusotomy, with biopsy." It accurately reflects both the surgical action being performed (the sinusotomy) and the additional step of obtaining a biopsy, thus ensuring that all aspects of the procedure are documented and billed correctly.

Other codes in the range do not describe a sphenoid sinusotomy with biopsy. For instance, 31049 refers to a different procedure without the biopsy component, while 31051 and 31052 represent additional variations of sinus procedures but do not directly cover the sphenoid sinusotomy with biopsy. Therefore, code 31050 is the appropriate choice for this specific surgical context.
