Hi legacyranch!
Great question. There is actually not a specific medical code for fluoride trays. You can either use the “D” code on the medical claim, or use a non-specific code and describe it in the narrative report such as:
99070 - Supplies and materials (except spectacles), provided by the physician or other qualified health care professional over and above those usually included with the office visit or other services rendered (list drugs, trays, supplies, or materials provided)
As for the mucositis treatment:
Diagnosis coding options:
K12.0 - Recurrent oral aphthae
K12.1 - Other forms of stomatitis
K12.31 - Oral mucositis (ulcerative) due to antineoplastic therapy
K12.32 - Oral mucositis (ulcerative) due to other drugs
K12.33 - Oral mucositis (ulcerative) due to radiation
K12.39 - Other oral mucositis (ulcerative)
T45.1X5 - Adverse effect, if applicable, to identify antineoplastic and immunosuppressive drugs
CPT/HCPCS coding
S8948 - Application of a modality (requiring constant provider attendance) to one or more areas; low-level laser; each 15 minutes.
41820 - Destruction of lesion, vestibule of mouth by physical methods
41850 - Destruction of lesion; dentoalveolar structures
42160 - Destruction of lesion, palate or uvula
Sample medical coverage policy from BCBS Florida titled "Infrared Energy Therapy and Low Level Laser Therapy which states “Low-level laser therapy meets the definition of medical necessity for prevention of oral mucositis in members undergoing cancer treatment associated with increased risk of oral mucositis, including chemotherapy and/or radiotherapy, and/or hematopoietic stem cell transplantation.”
