Answer: You'll find helpful information in your Novitas local coverage determination (LCD): www.novitas-solutions.com/policy/mac-ab/l27490-r12.html.

The LCD includes a section on documentation requirements that, along with the usual patient identification, order, and medical necessity requirements, states: "An ECG with interpretation must have the full graphic tracings with formal written interpretation on file for review. The interpretation should appear on the designated sections of a page formatted ECG or written in the clinical records. At a minimum, interpretations should include appropriate comments on rhythm, rate, axis, acute or chronic changes, and a comparison with the most recent tracing (if available). Appropriate measurements must be mentioned if the purpose of repeated ECGs is to monitor the effects of a given parameter, e.g., the QT interval. ECGs that are electronically read must be over-read, corrected and signed."
