Immediately: Billing team must retrieve and review the complete NCD 190.24 policy text from the CMS Medicare Coverage Database at https://www.cms.gov/medicare-coverage-database/data/ncd?ncdid=103&ncdver=1. Identify the specific CPT or HCPCS code(s) associated with digoxin therapeutic drug assay testing. Determine coverage criteria, required documentation, and any prior authorization requirements.

Failure to align billing practices with this new NCD could result in claim denials or payment delays for digoxin assay tests.
