Question:

Surgery of Primary Site--Head & Neck: Is a composite resection performed for an oral cavity primary coded to 40 [Radical excision of tumor, NOS], 41 [Radical excision of tumor only], 42 [Combination of 41 with resection in continuity with mandibles (marginal, segmental, hemi-, or total resection], 43 [Combination of 41 with resection in continuity with maxilla (partial, subtotal, or total resection)]? See discussion.

Discussion:

Example:

Patient underwent composite resection of left soft palate, tonsillar fossa, medial pterygoid and lateral tongue for a primary of the retromolar trigone. There was no mention of an excision of the mandible; however, the procedure included the application of a mandibular reconstruction plate.

Answer:

Use surgery codes 40-43 for composite resection of an oral cavity primary. In the case example, code Site-Specific surgery as 42 [Combination of 41 WITH resection in continuity with mandible]. Even though excision of mandible was not mentioned, there was mention of a mandibular reconstruction plate. Since the retromolar trigone is ON the mandible, resection of the mandible is likely.
