CPT® Code 83690 is used to report laboratory testing that measures lipase levels in the blood. Lipase is an enzyme primarily produced by the pancreas and plays a key role in fat digestion. Measuring lipase levels helps providers evaluate pancreatic function and diagnose or monitor conditions such as pancreatitis and other pancreatic disorders.
This test is commonly ordered when patients present with abdominal pain or symptoms suggestive of pancreatic disease.
Key Facts About CPT® 83690
Service type: Laboratory enzyme test
Provider type: Physicians and qualified healthcare professionals who order laboratory testing
Medical services included: Yes—measurement of lipase enzyme level in blood
Specimen type: Serum or plasma
Test method: Quantitative enzyme measurement
Common clinical indications:
- Evaluation of suspected acute or chronic pancreatitis
- Investigation of unexplained abdominal pain
- Monitoring pancreatic disorders or inflammation
- Assessing pancreatic injury or dysfunction
- Monitoring response to treatment for pancreatic conditions
When to Use CPT® 83690
CPT 83690 is appropriate when:
- A quantitative lipase test is ordered to evaluate pancreatic function

- Results are needed to diagnose, monitor, or rule out pancreatic disease
- The test is performed on a properly collected and processed blood specimen
Examples:
- Testing a patient presenting with severe upper abdominal pain suggestive of pancreatitis
- Monitoring lipase levels in a patient with known pancreatic inflammation
- Evaluating pancreatic enzyme levels following abdominal trauma
- Assessing pancreatic function in patients with suspected digestive disorders
Documentation Requirements
To support CPT 83690 billing, documentation should include:
- Patient identifiers and date of service
- Provider order for lipase testing
- Clinical indication or medical necessity
- Specimen type and collection date
- Test results and reference ranges
- Ordering provider credentials and signature
- Laboratory performing the test
Complete documentation supports accurate billing, compliance, and continuity of patient care.
Reimbursement and Coding Considerations
- CPT 83690 is reimbursed when medically necessary and properly documented
- Coverage varies depending on diagnosis, payer guidelines, and clinical indication
- Lipase testing is often performed alongside related tests such as amylase
- Each lipase test performed is billed as a separate service
- Verify payer-specific requirements for laboratory test billing
Accurate coding and proper documentation help ensure appropriate reimbursement and reduce claim denials.
