Oncotype DX Breast Cancer Assay Coding and Billing Guidelines (CM00024, V3)

Note: The OncotypeDX Breast Cancer Assay and the OncotypeDX DCIS Score are different tests and should NOT be submitted with the same Z-Code Identifier. Because this article ONLY addresses OncotypeDX Breast, the diagnosis codes for breast carcinoma in situ have been removed.

Oncotype DX® Breast was developed for patients with the following findings:

  • Estrogen-receptor positive, node-negative carcinoma of the breast
  • Estrogen-receptor positive micrometastases of carcinoma of the breast, and
  • Estrogen-receptor positive breast carcinoma with 1-3 positive nodes

To bill an Oncotype Breast service, please provide the following claim information:

  • Claims received prior to 1/1/2015: CPT code 81479 - unlisted molecular pathology
  • Claims received on and after 1/1/2015: CPT code 81519 - Oncology (breast)
  • Enter '1' in the Days/Unit field

Enter assigned Z-Code™ Identifier n the comment/narrative field for the following claim field/types:

  • Loop 2300 NTE 01 for part A or Loop 2400 or SV101-7 for Part B
  • Submit assigned Z-Code™ Identifier on an attachment to the claim form for paper claim (Form locator 80 for Part A or Box 19 for Part B)
