Summary & Overview
CPT 83009: Helicobacter pylori Urease Activity Test
Headline: CPT code 83009: Laboratory Test for Helicobacter pylori Urease Activity
CPT code 83009 documents a laboratory assay measuring Helicobacter pylori urease activity, commonly performed on a blood specimen to detect H. pylori infection, a known cause of gastric and duodenal ulcers. This code is used nationwide for billing and tracking of a specific diagnostic laboratory service that informs clinical management of peptic ulcer disease and related gastrointestinal conditions.
Major payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Coverage policies and reimbursement practices for serologic and urease-based H. pylori tests vary across payers and can affect access to testing and clinical pathway decisions.
Readers will find: concise clinical context for the test and why it matters for ulcer diagnosis; a summary of payer coverage landscape and common billing considerations; and benchmarks and policy updates relevant to laboratory services. The publication provides actionable administrative detail for billing staff, lab managers, and clinicians responsible for ordering and documenting diagnostic testing. Data not available in the input are noted where appropriate.
Billing Code Overview
CPT code 83009 measures Helicobacter pylori urease activity, typically performed on a blood sample to detect the presence of Helicobacter pylori, a bacterium associated with stomach and duodenal ulcers. The test identifies urease enzyme activity indicative of H. pylori infection.
Service Type: Laboratory infectious disease testing
Typical Site of Service: Clinical laboratory or hospital laboratory
Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to primary care with a 3-month history of epigastric pain, intermittent nausea, and dyspepsia. The clinician documents possible peptic ulcer disease and requests testing for Helicobacter pylori as part of the diagnostic workup. A phlebotomy technician draws a blood sample and sends it to the outpatient laboratory. The laboratory analyst performs a serologic urease activity assay to detect H. pylori antibodies/urease activity using code 83009. Results are reported to the ordering clinician, who uses the findings to guide decisions about noninvasive eradication therapy or further evaluation such as urea breath testing or endoscopy.
Typical site of service: Outpatient clinic visit with blood draw; hospital outpatient laboratory; independent clinical laboratory.
Typical workflow steps:
-
Patient presents to clinician with dyspeptic symptoms and is evaluated.
-
Clinician orders H. pylori testing and obtains blood for the
83009assay. -
Specimen is labeled, transported to the laboratory, accessioned, and analyzed by a lab technologist.
-
Results are reviewed and released to the ordering clinician (professional component), and the laboratory provides the technical processing (technical component).
