Salivary Glands Overview

Procedures in this group involve placement of radioactive sources or related brachytherapy techniques targeting salivary gland tissue to treat localized malignancies or other pathologic conditions of the salivary glands. They target the head and neck body system, specifically the major and minor salivary glands and adjacent structures. Accurate coding ensures the inpatient record reflects the specific therapeutic approach and devices used, which affects clinical documentation, case mix assignment, and reimbursement. Precision in code selection supports appropriate grouping and billing for complex inpatient care.

• An elderly patient with recurrent mucoepidermoid carcinoma of the parotid gland presents with facial pain and progressive local tumor growth causing skin invasion; the inpatient admission is for definitive tumor-directed therapy when external beam radiation is contraindicated or previously exhausted, and brachytherapy is used to deliver high-dose localized radiation directly to the tumor bed. Codes: D91697Z, D91698Z
• A middle-aged patient with an inoperable primary submandibular gland malignancy and acute obstructive symptoms is admitted electively for planned interstitial brachytherapy as part of a multi-modality curative approach to limit damage to surrounding structures; the procedure is performed under anesthesia with image guidance to implant radioactive sources. Codes: D91699Z, D9169BZ
• A patient with prior brachytherapy for salivary gland cancer develops a recurrent radiogenic ulcer and persistent tumor requiring salvage inpatient management; the case involves revision or replacement of prior brachytherapy implants or removal of malfunctioning sources during the admission. Codes: D916B6Z, D916BBZ
