Diagnostic tests

Article Overview

This article explains a common diagnosis coding issue for diagnostic tests such as screening and symptom-driven evaluations. It is aimed at coders, billers, and compliance staff who need to understand how payers view screening versus medically necessary services, and how the reason for testing should be reflected in the claim. The discussion focuses on general coding practice, Medicare-related screening concerns, payer variability, and the importance of coding to the patient’s presentation without relying on uncertain diagnoses.
