In simple words: This code is used in a special Medicare project to track how colon cancer is treated. It means the cancer has spread but isn't currently showing signs of growing.

This code reports the disease status of a patient's colon cancer as part of a Medicare demonstration project. It indicates limited to invasive adenocarcinoma at metastasis category M1, with a metastatic, locally recurrent, or progressive condition, but without current clinical, radiologic, or biochemical evidence of the disease.

Example 1: A patient with a history of stage III colon cancer, treated with surgery and chemotherapy, is now in remission with no evidence of disease but is being monitored for recurrence. The oncologist reports G9088 to indicate the patient’s disease status under the Medicare demonstration project., A patient with metastatic colon cancer undergoes radiographic imaging and blood tests which show no evidence of active disease. The oncologist reports G9088 as part of the Medicare demonstration project., A patient with a history of colon cancer is experiencing new symptoms concerning for recurrence. Following investigation, the symptoms are attributed to another condition. G9088 is reported to indicate the patient's status within the Medicare project.

Documentation should include the primary focus of the patient’s visit, the status of the disease, and adherence to practice guidelines, as required by the Medicare demonstration project. This includes relevant clinical findings, imaging results, laboratory data, treatment plans, and follow-up notes.

** This code is used in conjunction with other CPT codes to provide a comprehensive overview of the patient's condition and treatment plan. It is specifically for use in the Medicare demonstration project for oncology patients and should not be used for other billing purposes. Only providers specializing in hematology and oncology can participate in this project, which applies exclusively to Medicare patients not enrolled in a Medicare Advantage plan.
