Answer: Coding an endoscopic cricopharyngeal myotomy can prove tricky. At first glance, you may assume the correct code is 43130 (Diverticulectomy of hypopharynx or esophagus, with or without myotomy; cervical approach).
Problem: Code 43130 describes an open surgery. Because the otolaryngologist in your example uses an endoscopic, rather than a cervical approach, you should instead use unlisted procedure code 43499 (Unlisted procedure, esophagus).
Best practice: You should also write a letter to the CPT AMA Committee (address in front of CPT book) and the Practice Management Board of the Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS). Explain to the members that the otolaryngologist is performing cricopharyngeal myotomy endoscopically.
You should take this extra step every time that a surgeon performs a CPT defined open surgery endoscopically. Alerting the proper agencies that surgeons are now performing the open surgery endoscopically helps the boards eventually obtain CPT codes to describe the endoscopic surgery.
