The Hepatobiliary Iminodiacetic Acid (HIDA) scan, also known as a cholescintigraphy, is a nuclear medicine procedure used to visualize the gallbladder, bile ducts, and liver. Understanding the appropriate CPT code for billing purposes is crucial for both healthcare providers and patients. This guide will delve into the specific CPT codes associated with HIDA scans and address frequently asked questions.
What is a HIDA Scan and Why is it Performed?
A HIDA scan uses a radioactive tracer injected into a vein. This tracer travels through the liver, gallbladder, and bile ducts, allowing a special camera (gamma camera) to capture images and assess their function. Physicians order HIDA scans to diagnose various conditions, including:
- Gallbladder disease: Detecting gallstones, cholecystitis (gallbladder inflammation), and biliary dyskinesia (abnormal gallbladder emptying).
- Bile duct obstruction: Identifying blockages in the bile ducts due to gallstones, tumors, or inflammation.
- Liver disease: Assessing liver function and bile production.
- Evaluation of jaundice: Determining the cause of jaundice (yellowing of the skin and eyes).
CPT Codes for HIDA Scans: Deciphering the Nuances
The CPT code for a HIDA scan isn't a single, universally applicable code. The specific code depends on the complexity and components of the procedure. Several codes might be used, often in conjunction. It's vital to accurately document the procedure performed to ensure correct coding. Common codes include (but are not limited to):
-
74321: This code typically represents a basic HIDA scan. However, the specifics of what constitutes a "basic" scan can vary slightly depending on local practices and payer requirements. Always consult the most up-to-date CPT manual.
-
74322: This code might reflect a more complex HIDA scan, possibly involving additional imaging or analysis beyond the standard procedure. This could encompass post-cholecystokinin (CCK) stimulation or prolonged imaging times. Again, precise documentation is paramount.
-
Additional codes for related services: You might find that additional CPT codes are needed to bill for other services rendered during the HIDA scan procedure, such as intravenous administration, or if other imaging modalities are combined.
What Factors Determine the Specific CPT Code Used?
Several factors influence the CPT code assigned to a HIDA scan:
- Procedure performed: The specific imaging sequences and steps undertaken. Was CCK administered? Was there any unusual delay or intervention?
- Interpretation and report: The radiologist's reading and report writing will influence the billing process and may warrant additional codes.
- Imaging facility and payer: Local practices and payer policies vary.
- Medical necessity: The specific reasons the physician ordered the HIDA scan will be essential in determining the appropriate code.

Always consult the most current CPT manual and seek guidance from a qualified medical billing specialist to ensure accurate coding and compliance with all relevant regulations.
How Much Does a HIDA Scan Cost?
The cost of a HIDA scan can vary depending on several factors, including the location of the facility, the complexity of the procedure, insurance coverage, and whether additional tests are required.
What are the Risks and Side Effects of a HIDA Scan?
The risks associated with a HIDA scan are generally low. However, there is a small risk of an allergic reaction to the radioactive tracer. The amount of radiation exposure is relatively small and generally considered safe.
Does Insurance Cover a HIDA Scan?
Most insurance plans cover medically necessary HIDA scans. However, it's essential to check with your insurance provider to confirm coverage and understand any out-of-pocket expenses.
How Do I Prepare for a HIDA Scan?
Preparation instructions for a HIDA scan may vary, so it's vital to follow the instructions given by your physician or the imaging center. Usually, fasting for a specific period before the scan is required.
This comprehensive guide aims to offer clarity regarding HIDA scan CPT codes. Remember to consult medical billing professionals and the latest CPT manual for accurate coding and reimbursement.
