Microlaryngoscopy with vocal cord fat injection
A patient with dysphonia presented for fat injections into the vocal cords. A mouth guard was placed and a Dedo laryngoscope was used to directly visualize the glottis. No abnormalities were noted on the vocal folds. General anesthesia was induced and the patient prepped for abdominal fat graft harvest. A stab incision was made inferior to the umbilicus. A cannula with an attached syringe was used to harvest about 25cc of fat. The harvested fat was rinsed, the tissue minced with scissors and loaded into the injector device. The stab incision was closed in simple interrupted fashion, and steri-strips were applied. The patient was then placed in suspension with a view of the bilateral vocal folds. The previously harvested fat was injected into the true vocal folds until adequate medialization of the vocal folds was achieved. At this time, the laryngoscope and mouth guard were removed. What is the correct code assignment for fat injection into the vocal cords via a suspension microlaryngoscopy with fat harvested from the abdomen via suction? Is the fat harvesting separately reported? ...

Article Overview
This article discusses a microlaryngoscopy-based laryngeal procedure in which autologous fat is harvested and injected to support the vocal folds. It is relevant to coding professionals working with otolaryngology, laryngeal surgery, and procedures that combine tissue harvest with endolaryngeal injection. The article focuses on how to think about the procedural components, the operative setting, and the code assignment question tied to this type of case.
Why This Topic Matters
Cases like this often involve multiple procedural components and can be difficult to code accurately without understanding which services are being performed and how the operative approach is documented. Clear interpretation helps support consistent coding in ENT and surgical billing workflows.
