Effective Date: N/A Medicare Demonstration Projects Feed
Oncology - other. Current Disease Status of Oncology, Colon Cancer, Limited to Invasive, Adenocarcinoma Predominant, T1-T3, N0, M0, No Evidence of Progression, Recurrence or Metastases.
This code is used for reporting purposes within a specific Medicare demonstration project focused on colon cancer. The medical necessity is established by the patient's diagnosis of colon cancer and participation in the project.
Hematology and oncology specialists participating in the Medicare demonstration project are responsible for reporting this code along with CPT codes related to the patient visit's primary focus, disease status, and adherence to practice guidelines. This applies only to Medicare patients not enrolled in a Medicare Advantage plan.
In simple words: This code is used in a special Medicare project to track information about colon cancer. It means the cancer is limited and hasn't spread to lymph nodes or other parts of the body. The cancer is at an early stage (T1-T3) and is mainly made up of adenocarcinoma cells. There are no signs the cancer is getting worse or coming back.
This code reports the current disease status of a patient's colon cancer as part of a Medicare-approved demonstration project. It signifies limited to invasive colon cancer where adenocarcinoma is the predominant cell type. The extent of the disease is classified as T1-T3, with no lymph node involvement (N0) and no distant metastasis (M0). Additionally, there's no evidence of disease progression, recurrence, or metastases.
Example 1: A patient with newly diagnosed, limited invasive colon cancer classified as T2, N0, M0, with adenocarcinoma as the main cell type, is seen by a participating oncologist. The oncologist reports G9084 along with other required CPT codes for this Medicare demonstration project., A patient undergoing treatment for colon cancer is reevaluated, and the cancer remains limited to invasive (T3, N0, M0) with no evidence of progression. The oncologist uses G9084 to reflect the ongoing disease status within the demonstration project., A patient in remission from colon cancer is monitored. The latest tests confirm no recurrence or metastasis and the disease status remains stable at T1, N0, M0. The oncologist uses G9084 for reporting purposes within the demonstration project.
Documentation should include the complete TNM staging (T1-T3, N0, M0), confirmation of adenocarcinoma as the primary cell type, and a statement confirming no evidence of disease progression, recurrence, or metastases. The documentation should also include the CPT® codes for the primary focus of the patient's visit, the disease status, and the adherence to practice guidelines.
