Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 88120 covers

This service uses fluorescent in situ hybridization to assess cells in a urinary tract specimen for chromosomal changes associated with urothelial carcinoma. It is commonly used in the evaluation or surveillance of patients with a history of bladder cancer, including when urine testing is used to look for evidence of recurrent disease. Laboratory personnel prepare and process the specimen; a pathologist interprets the findings. The code represents analysis with three to five probes for each specimen, rather than conventional microscopic urine cytology.

Report one unit for each specimen analyzed under the three-to-five-probe method. Documentation should identify the specimen, the FISH analysis performed, the probes or probe set used, and the interpreted result. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff work. Report without either modifier when billing the global service, which includes both components.
