Current Review Results

In order to fulfill its contractual obligation with CMS, Noridian Healthcare Solutions (Noridian), your Medicare Contractor, performs pre -payment reviews in accordance with CMS direction. CMS is required by the Social Security Act to ensure that payment is made only for those medical services that are reasonable and necessary. Medical review assesses submitted documentation to validate provider compliance with Medicare payment rules and regulations, including coverage, coding and billing guidelines.

This is to update providers of the claim review findings for HLA - Histocompatibility Testing Services. The results of this focused review are not a reflection on providers’ competence as a health care professional or the quality of care provided to patients. Specifically, the results are based on the documentation requested by Medicare and/or your facility’s compliance with the required documentation.

Summary of Findings

Since the initiation of the review, 175 claims were reviewed from February 5, 2024, to October 10, 2024. The breakdown of those findings are as follows:

• 40 claims were allowed.
• 135 claims were denied in full for the following reasons:
• Failure to return records
• The documentation submitted does not support medical necessity as listed in coverage requirements in the National Coverage Determination or Local Coverage Determination.
  • Documentation did not support National Coverage Determination (NCD) 190.1

The overall error rate since the initiation of this service specific probe review is 77.01%. The error rate is calculated by dividing the dollar amount of charges billed in error (minus any confirmed under-billed charges) by the total amount of charges for services medically reviewed. If you disagree with a claim determination, the normal appeal process may be followed as directed on the Noridian website under Appeals or as directed in your claim remittance advice, although this will not affect the error rate of the pre-payment review.

Education

National Coverage Determination 190.1 "Histocompatibility Testing" discusses the coverage requirements for these services. This can be located within the Internet-Only Manuals (IOM), Medicare National Coverage Determinations (NCD) Manual, Publication 100-03, chapter 1, Part 3, Section 190.1 at Medicare National Coverage Determinations Manual.

Histocompatibility testing involves the matching or typing of the human leucocyte antigen (HLA). This testing is safe and effective when it is performed on patients:

1. In preparation for a kidney transplant;
2. In preparation for bone marrow transplantation;
3. In preparation for blood platelet transfusions (particularly where multiple infusions are involved; or
4. Who are suspected of having ankylosing spondylitis. This testing is covered under Medicare when used for any of the indications listed in A, B, and C and if it is reasonable and necessary for the patient.

It is covered for ankylosing spondylitis in cases where other methods of diagnosis would not be appropriate or have yielded inconclusive results. Request documentation supporting the medical necessity of the test from the physician in all cases where ankylosing spondylitis is indicated as the reason for the test.
