Imaging codes

Echo and nuclear are two-part studies. Each code has a professional part, the read, and a technical part, the machine and the staff. The guides show which part each code pays and who bills it.

A practice that owns the equipment and reads its own studies bills the global code. A cardiologist reading for a hospital bills the read with modifier 26.

02Testing

Testing codes

Stress tests split into supervision, tracing and interpretation. Which parts you bill depends on where the test was done and who was in the room.

The stress test guide covers treadmill, stress echo and nuclear in one place. Its code table goes by setting. It also covers the drug lines for Lexiscan, adenosine and dobutamine.

How these guides stay current

Codes, coverage rules and payer policies change every year. We update these guides when a code family changes, and we add guides as codes change.

These guides are what our coders use. The service pages, starting with What we bill, show how the same coders work your claims.
