(Medicare Claims Processing Manual)

Sincerely,  370  Microvolt T -wave Alternans (MTWA)  (Rev. 3265, Issued: 05- 22-15, Effective: 01 -13-15, Implementation: 06-23-15)  On March 21, 2006, the Centers for Medicare & Medicaid Services (CMS) began national coverage of microvolt T -wave Alternans (MTWA) diagnostic testing when it was performed using only the spectral analysis (SA) method for the evaluation of patients at risk for sudden cardiac death (SCD) from ventricular arrhythmias and patients who may be candidates for Medicare coverage of the placeme nt of an implantable cardiac defibrillator (ICD).   Effective for claims with dates of service on and after January 13, 2015, Medicare Administrative Contractors (MACs) may determine coverage of MTWA diagnostic testing when it is performed using methods of analysis other than SA for the evaluation of patients at risk for SCD from ventricular arrhythmias.  Further information can be found at Publication 100-03, section 20.30, of the National Coverage Determinations Manual.   370.1 - Coding and Claims Processing for MTWA  (Rev. 12396; Issued: 12- 07-23; Effective: 01 -09-24; Implementation: 01 -09-24)  Effective for claims with dates of service on and after March 21, 2006, MACs shall accept CPT 93025 (MTWA for assessment of ventricular arrhythmias) for MTWA diagnostic testing for the evaluation of patients at risk for SCD with the SA method of analysis only. All other methods of analysis for MTWA are non -covered.   Effective for claims with dates of service on and after January 13, 2015, MACs shall at their discretion determine coverage for CPT 93025 for MTWA diagnostic testing for the evaluation of patients at risk for SCD with methods of analysis other than SA. The  KX modifier shall be used as an attestation by the practitioner and/or provider of the service that documentation is on file verifying the MTWA was performed using a method of analysis other than SA for the evaluation of patients at risk for SCD from ven tricular arrhythmias and that all other NCD criteria was met.   NOTE: The KX modifier is NOT required on MTWA claims for the evaluation of patients at risk for SCD if the SA analysis method is used.  NOTE: This diagnosis code list/translation was approved by CMS/Coverage. It may or may not be a complete list of covered indications/diagnosis codes that are covered but should serve as a finite starting point.  As this policy indicates, individual A/B MACs within their respective jurisdictions have the discretion to make coverage determinations they deem reasonable and necessary under section 1862(a)(1)(A) of the Social Security Act. Therefore, A/B MACs may have additional covered diagnosis codes in their individual policies where contractor discretion is appropriate.
