ABN’s Lab ICD-10 Search Tool

What is the A-List?

A-LIST is designed as a search tool to aid in the selection of medically acceptable diagnostic codes for test groups included in the National Coverage Determination (NCD) and Local Coverage Determination (LCD) documents. The documents are in PDF format and easily searched. The responsibility for properly and correctly navigating the A-LIST for Medicare coding remains with the physicians and their staff. The A-LIST is simply a search tool offered for the convenience of physicians and not a substitute for the professional judgment required of the physicians. The use of this search tool constitutes a waiver of all claims against MMC, its affiliates and employees, arising from the use of the search tool and coding taken therefrom.

How do I find the diagnostic information I need?

The home page contains the following information:

  • Complete National Coverage Determination (NCD) document.
  • National Coverage Determination (NCD) test groups.
  • Local Coverage Determination (LCD) test groups.

Within each test group, there are 3 main documents:

  • Complete NCD/LCD specific to test group
  • Acceptable ICD-10 codes associated with MMC test
  • Details such as Description, Indications, and Limitations (Time-specific information and coding suggestions may be found in Details).

Additional Coding Guidelines for CMS tests referred to in this section are found in the front section of the complete NCD document.) To search for specific information, simply click on the desired category of the test group. A document will open in a PDF format.

Additional information, including shortcuts, can be found in this document.

National Coverage Determination (NCD)

The Medicare National Coverage Determinations (NCD) Coding Policy Manual and Change Report (ICD-10-CM) from the U.S. Department of Health & Human Services Centers for Medicare & Medicaid Services provides complete NCD documentation.

Local Coverage Determination (LCD)


Local Coverage Determination (LCD) are written differently than the NCD documents. Some test groups have specific coverage determinations for each test, and some test groups have special conditions.
