CCC Cardiac Diagnostic Testing & Monitoring Coding 2 — Questions and Answers
Question 1: Which CPT code describes a complete transthoracic echocardiogram including real-time 2D imaging, M-mode, spectral Doppler, and color flow Doppler?
- 93306 (Correct answer)
- 93307
- 93308
- 93303
Correct answer: 93306
CPT 93306 represents the most complete standard transthoracic echocardiogram, including real-time 2D, M-mode recording when performed, spectral Doppler, and color flow Doppler.
Question 2: CPT 93307 differs from CPT 93306 in that it describes a complete transthoracic echocardiogram that:
- Includes color flow Doppler mapping only
- Is limited to spectral Doppler evaluation only
- Does not include spectral or color Doppler (Correct answer)
- Requires a transesophageal approach
Correct answer: Does not include spectral or color Doppler
CPT 93307 describes a complete transthoracic echocardiogram performed without any Doppler component, distinguishing it from 93306 which includes both spectral and color Doppler.
Question 3: A complete transesophageal echocardiogram (TEE) is performed with probe placement, image acquisition, interpretation, and report. Which CPT code applies?
- 93306
- 93312 (Correct answer)
- 93315
- 93320
Correct answer: 93312
CPT 93312 describes the complete TEE service including probe placement, real-time imaging, and physician interpretation and report.
Question 4: A cardiologist performs only the interpretation and written report of an echocardiogram performed at a hospital. Which modifier is appended to the echocardiography code?
- Modifier 26 (Correct answer)
- Modifier TC
- Modifier 59
- Modifier 25
Correct answer: Modifier 26
Modifier 26 indicates the professional component only (interpretation and report) when the facility provides the technical component (equipment, room, and technician).
Question 5: Which CPT code describes a complete transthoracic echocardiogram performed specifically for congenital cardiac anomalies?
- 93306
- 93303 (Correct answer)
- 93315
- 93307
Correct answer: 93303
CPT 93303 describes transthoracic echocardiography for congenital cardiac anomalies, including a complete study with 2D imaging and Doppler where indicated.
Question 6: Which CPT add-on code is reported when an echo contrast agent is used for left ventricular opacification during echocardiography?
- 93320
- 93325
- 93352 (Correct answer)
- 93308
Correct answer: 93352
CPT 93352 is the add-on code for use of an echo contrast agent for LV opacification and/or defect enhancement and is reported in addition to the primary echocardiography code.
Question 7: A limited transthoracic echocardiogram is performed to re-evaluate a previously diagnosed pericardial effusion. Which CPT code is most appropriate?
- 93306
- 93307
- 93308 (Correct answer)
- 93303
Correct answer: 93308
CPT 93308 describes a limited or follow-up transthoracic echocardiogram, appropriate when only specific structures are evaluated rather than a complete study.
