Nuclear medicine
About 78227: Hepatobiliary scan with drug intervention
Reports hepatobiliary nuclear imaging with a medication intervention, such as stimulation of gallbladder emptying, when the clinical question requires a drug-assisted study.
A nuclear medicine team administers a hepatobiliary radiotracer and obtains images of tracer movement through the liver and biliary system, including the gallbladder when present. A medication may be used to stimulate gallbladder contraction for an emptying assessment or to alter biliary transit. Studies may help evaluate suspected gallbladder dysfunction or selected biliary disorders. A nuclear medicine physician interprets the images; technologists typically perform the acquisition in a hospital or imaging center.
Choose this code when the study includes pharmacologic intervention, rather than imaging without that intervention. The report should identify the medication and its purpose, describe the imaging and any quantitative measurements, and document the clinical question and interpretation. CMS recognizes a professional component for interpretation and a technical component for equipment and staff: report modifier 26 for the professional service, modifier TC for the technical service, or neither modifier when billing the global service. The study’s medication intervention is part of the described imaging service; radiopharmaceutical supply may be represented by a separate applicable code.

78227 billing questions
How does this differ from 78226?
Use 78227 when the hepatobiliary imaging includes a pharmacologic intervention. Use 78226 for hepatobiliary imaging without that intervention.
Can the interpretation and imaging be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
What should the report document?
Document the medication used and why, the imaging performed, any quantitative measurements, and the physician’s findings and interpretation.
Is this reported once per image or view?
Report the imaging study, not each image or view. The medication-assisted assessment and any quantitative measurements belong to the study.
Can the radiopharmaceutical supply be reported separately?
A hepatobiliary radiopharmaceutical supply code may be relevant, such as A9537 or A9512. The applicable supply billing depends on the setting and the claim circumstances.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
