About 93325: Color flow Doppler echocardiography add-on
Report color flow Doppler mapping with a qualifying transthoracic, transesophageal, stress, or fetal echocardiogram whose primary code does not include color flow.
Color flow Doppler overlays blood flow direction and velocity onto two-dimensional echo images, helping identify valvular regurgitation, stenotic jets, intracardiac shunts, and prosthetic valve flow. Sonographers acquire images in cardiology offices and hospitals; cardiologists interpret them, while fetal studies may involve pediatric cardiologists or maternal-fetal medicine specialists. Mapping accompanies a qualifying transthoracic, transesophageal, stress, or fetal echocardiogram whose primary code excludes color flow.
Report this add-on with a qualifying primary echo; it is paid within that procedure’s global period. Examples include limited TTE (93308), complete TTE with color Doppler alone (93307), congenital TTE (93303 or 93304), TEE (93312 or 93315), stress echo (93350 or 93351), and fetal echo (76825 or 76826). When both spectral and color Doppler accompany a complete standard TTE, report 93306 instead of separate Doppler add-ons. Document the primary study and color flow findings, such as a regurgitant jet or shunt direction. Report one unit for the color mapping, not one per valve or jet. Modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and billing without either modifier represents the global service.
CMS billing rules for 93325
- Global period
- Add-on code: billed only together with a primary procedure and paid within that procedure's global period.
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

93325 compared with similar codes
Office rates for Missouri, from the same CMS release.
$46.12–$49.59
93320 covers complete spectral Doppler; 93325 covers color flow mapping. Both may be reported when both techniques accompany a qualifying primary echo.
$22.61–$24.42
93321 covers limited or follow-up spectral Doppler. 93325 has no complete-versus-limited distinction and covers color flow mapping.
$123.24–$132.85
93307 is a complete TTE without Doppler. Add 93325 when color flow mapping alone is performed; use 93306 when the complete TTE includes both spectral and color Doppler.

93325 billing questions
Can 93325 be reported with a complete transthoracic echo, 93306?
No. 93306 already includes spectral and color flow Doppler, so adding 93325 would duplicate the color flow service.
Can 93325 be added to 93307 when color Doppler is performed?
Yes, when color flow mapping accompanies the complete TTE without spectral Doppler. When the complete TTE includes both spectral and color Doppler, report 93306 instead.
How many units of 93325 are reported per study?
Report one unit for color flow mapping with a qualifying echocardiogram, regardless of how many valves or shunts are assessed.
Which modifier applies when the physician only reads the study in a hospital?
Append modifier 26 to 93325 for the physician’s interpretation. Bill the primary echo code according to the component the physician furnished; modifier TC identifies the technical portion of 93325.
Is 93325 reported with spectral Doppler codes 93320 or 93321?
Yes, when both spectral and color Doppler are performed with a qualifying primary echo. Report the applicable spectral Doppler add-on and 93325 separately.
Is color flow Doppler separately reportable with TEE guidance for structural heart interventions, 93355?
No. 93355 includes color flow Doppler when performed as part of the TEE guidance.
