Q: A patient has been diagnosed with peritonsillar cellulitis and oropharyngeal cellulitis. The physician documents that he performed a “needle aspiration of the left peritonsillar abscess.” In the body of the operative report, the physician states, “An 18-gauge needle was inserted and 1 cc of pus was aspirated. This was sent for aerobic, anaerobic, C&S [culture & sensitivity], and gram stain. I then put the 18-gauge needle in again and multiple passes were obtained without any aspirate.”

Because ICD-9-CM does not include a code for “aspiration of peritonsillar abscess” some coders wanted to use ICD-9-CM procedure code 28.0 (incision and drainage of tonsil and peritonsillar structures) while others want to report code 28.99 (other operations on tonsils and adenoids). Which code is correct?
 
A: Based on what you wrote here, code 28.0 (drainage of peritonsillar abscess) is appropriate. The incision is the insertion of the 18-gauge needle and the drainage can be performed by aspiration or other methodology.
 
In addition, you will need a diagnosis code to report the existence of the abscess that was drained (aspirated). Cellulitis is an inflammation whereas an abscess is a collection of purulent or other fluid. Take a look at ICD-9-CM code 475 (peritonsillar abscess).
