Microvolt T-Wave Alternans (MTWA) Diagnostic Testing
Effective for dates of service on or after March 21,
2006, MTWA diagnostic testing is covered for the evaluation of patients at risk of sudden
cardiac death, only when the spectral analysis method is used. Prior to this CR, MTWA
was covered based on contractor discretion. This addition of section 20.30 of Pub. 100-03
is a National Coverage Determination (NCD) made under section 1862(a)(1) of the
Social Security Act. NCDs are binding on all carriers, fiscal intermediaries, quality
improvement organizations, health maintenance organizations, competitive medical
plans, health care prepayment plans, the Medicare Appeals Council, and administrative
law judges (see 42 CFR section 405.1064, effective May 1, 2005). An NCD that expands
coverage is also binding on a Medicare advantage organization. In addition, an
administrative law judge may not review an NCD. (See section 1869(f)(1)(A)(i) of the
Social Security Act.)
