What 76776 covers
This study evaluates a renal allograft with real-time ultrasound and Doppler assessment of the transplant vessels. It is commonly ordered for graft dysfunction, rising creatinine, reduced urine output, suspected obstruction, or concern for vascular compromise after kidney transplantation. Sonographers acquire and document the images; a radiologist or other qualified physician interprets the examination, often in a hospital or outpatient imaging setting.
Report 76776 for an ultrasound of the transplanted kidney that includes Doppler evaluation; a study of native kidneys or the broader retroperitoneum is selected according to its scope instead. Documentation should identify the graft, support the ultrasound and Doppler work performed, and include the interpretation. CMS allows global billing without a modifier, or separate professional and technical billing with modifiers 26 and TC. The diagnostic imaging multiple procedure reduction applies to both components.

- 76775Retroperitoneal ultrasound
- 76775 describes a limited retroperitoneal ultrasound. It does not identify the transplant-kidney Doppler service represented by 76776.
- 93975Vascular duplex
- 93975 describes a duplex examination of abdominal organ vessels. 76776 is the transplant-kidney ultrasound that includes Doppler assessment of the graft vessels.
76776 billing questions
How does 76776 differ from a native-kidney ultrasound?
76776 is specific to the transplanted kidney and includes Doppler assessment of its vessels. Use a retroperitoneal ultrasound code when the examination is of native kidneys or the broader retroperitoneum.
Is Doppler reported separately from 76776?
The transplant-vessel Doppler assessment is included in 76776. Do not report a separate duplex service for the same Doppler work.
How are the professional and technical portions billed?
Bill globally without a modifier, or report modifier 26 for the professional interpretation and modifier TC for the technical service. CMS applies the diagnostic imaging multiple procedure reduction to both components.
What documentation supports reporting 76776?
Document that the examination concerns a transplanted kidney, the ultrasound and Doppler evaluation performed, and the interpreting provider's findings. Clinical context such as graft dysfunction or suspected obstruction can support why the study was ordered.
Are units based on the number of vessels examined?
No. Report the transplant-kidney ultrasound study, not separate units for individual vessels assessed during its Doppler evaluation.
