Question:
Surgery of Primary Site--Lymphoma/Soft Tissue: How is this field coded for an excision of a neck mass that found lymphoma in soft tissue (C49.0)? See Discussion.
Discussion:
CT scan showed soft tissue mass in the retropharynx. 9/23/2008 Laryngoscopy with biopsy taken of left tonsil and left base of tongue and random biopsies of nasopharynx; FNA of left neck. Path stated left tonsil, squamous papilloma. Left base of tongue, no significant histopathology. Nasopharynx biopsies, compatible with tonsillar tissue. Pretracheal lymph node biopsies, mild reactive lymphoid hyperplasia. 9/30/2008 Excision of left neck mass with limited deep jugular chain lymph node dissection. Path stated lymph node left jugular biopsy, no tumor seen. Soft tissue, left neck biopsy, malignant B cell lymphoma with plasmacytoid differentiation. Addendum from consult: favor a diagnosis of a marginal zone lymphoma. Per the gross description, the specimen was fibrofatty connective tissue in which there is a tumor infiltrate.
Answer:
Assign code 26 [partial resection]. Use the surgery codes that apply to the primary site. See page C-597 of the 2007 SEER manual for surgery of primary site codes applicable to primary sites of soft tissue coded to C490 - C499.
