CMS National Coverage Policy

Title XVIII of the Social Security Act, Section 1833 (e). This section states that no payment shall be made to any provider for any claims that lack necessary information to process the claim.

Title XVIII of the Social Security Act section 1862 (a)(1)(A). This section allows coverage and payment of those services that are considered to be medically reasonable and necessary.

Title XVIII of the Social Security Act section 1862 (a)(7). This section excludes routine physical examinations and services.

CMS Manual System, Pub 100-08, Medicare Program Integrity Manual, Chapter 3, Part 3.2.3 Requesting Addition Documentation During Prepayment and Post-payment review.

42 CFR Section 410.32(a) indicates diagnostic tests are payable only when the physician who is treating the beneficiary for a specific medical problem uses the results in such treatment.

Article Guidance

Article Text

This article contains coding and other guidelines that complement the Local Coverage Determination (LCD) for Autonomic Function Testing.

Coding Information:

Procedure codes may be subject to National Correct Coding Initiative (NCCI) edits or OPPS packaging edits. Refer to NCCI and OPPS requirements prior to billing Medicare.

For services requiring a referring/ordering physician, the name and NPI of the referring/ordering physician must be reported on the claim.

A claim submitted without a valid ICD-10-CM diagnosis code will be returned to the provider as an incomplete claim under Section 1833(e) of the Social Security Act.

The diagnosis code(s) must best describe the patient's condition for which the service was performed. For diagnostic tests, report the result of the test if known; otherwise the symptoms prompting the performance of the test should be reported.

Do not report 95922 in conjunction with 95921

Documentation Requirements:

  1. Medical record documentation maintained by the performing provider must clearly support the medical necessity for ANS testing as well as the test reports and interpretation. Supportive documentation showing medically reasonable and necessary indications as outlined in this LCD are expected to be documented in the medical record and be available upon request. This documentation includes, but is not limited to, relevant medical history, physical examination and results of pertinent diagnostic tests or procedures used to rule out more common causes of autonomic signs or symptoms.
  2. General professional standards with FDA clearance apply for all equipment used in ANS testing.

Utilization Guidelines:

  1. Diagnostic testing may be allowed once to confirm or exclude specific autonomic disease.
  2. For patients with diagnosed autonomic disorders, repeat testing is governed by a change in clinical status or response to a therapeutic intervention. If a repeat test is needed, it is not expected to exceed once per year.
  3. Providers who perform these tests on an unusually high proportion of their patients, or at frequencies exceeding once per year may be subject to medical review.
  4. Providers who do not have tilt tables and are using the code range 95921-95924 may be subject to medical review.

Group 2 Paragraph

CPT 95999 should be used to report testing other than autonomic nervous system function testing. If a physician finds that this non-standardized component information of autonomic function testing (AFT) is useful in a patient assessment and clinical decision making given certain patient risks/signs/symptoms, this would be included in the physician’s basic evaluation and management service and not separately covered. In addition, testing patients prior to the development of symptomatic autonomic neuropathy would be screening, and there is no such screening Medicare benefit with the absence of disease.
