Article Guidance

Article Text

The billing and coding information in this article is dependent on the coverage indications, limitations and/or medical necessity described in the related LCD.

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. 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. 
  2. 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.
  3. Providers who do not have tilt tables and are using the code range 95921-95924 may be subject to medical review.
