Could you help me with the medical claim coding for custom fluoride trays for a patient that had treatment for oral cancer? The radiation causes a decrease in saliva production, resulting in a dry mouth-which leads to an increase in tooth decay. So, the fluoride trays are a preventative measure against tooth decay. I need the medical billing codes (not the dental, as his dental insurance will not pay for the trays.) Thank you!
You would need to code the appropriate oral cancer code (170.1, 198.5, ect) as the initial diagnosis and Xerostomia (527.7) as the secondary diagnosis.
Since fluoride trays are not typically a covered procedure under medical and there is no specific code the most appropriate procedure or CPT code would be 21089. This code will need a brief narrative to accompany the claim.
