Maxillectomy with Reconstruction of Maxilla
A patient with mucosal melanoma involving the left maxillary alveolus and sinus is admitted for left maxillectomy with obturator reconstruction. The surgeon proceeded with an inferior and anterior wall maxillectomy including resection of the medial maxilla and pterygoid wedge, down below the level of the infraorbital foramen. Once it was felt that wide surgical margins were achieved, a prefabricated obturator was placed, completely filling the maxillary defect. In this case, the primary objective of the maxillectomy is to remove cancerous tissue, which is a distinct objective from the reconstruction. Can the rationale for mastectomy with reconstruction published in Coding Clinic, Third Quarter 2018, page 13, be applied in this case with separate codes assigned for the maxillectomy and obturator placement? ...

Article Overview
This article explains a surgical coding scenario involving maxillectomy with reconstruction of the maxilla and discusses how published coding guidance may apply when the operative goals include both removal of disease and reconstruction. It is intended for inpatient coders, coding educators, and auditors who work with ICD-10-PCS and need to understand how related procedure concepts are discussed in official coding guidance.
Why This Topic Matters
Procedure coding for head and neck oncology cases can be nuanced when surgery and reconstruction occur in the same encounter. This article helps readers evaluate how published coding guidance is applied in similar scenarios and why the coding approach matters for accurate reporting.
