Helicobacter pylori Culture

Helicobacter pylori Culture

CPT Test code: 87081;7205

Test Includes: Culture; smear for modified Gram stain (reported only if positive and culture does not grow); isolation and identification (additional charges/CPT code[s] may apply). CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed.
Related Information:
Specimen: Gastric material
Volume: Biopsy
Container: Anaerobic transport, aerobic/anaerobic bacterial swab transport system, CLO vial, urea agar medium
Storage Instructions: Maintain specimen at room temperature.
Causes for Rejection: Inappropriate specimen transport device; improper labeling; specimen received after prolonged delay (usually more than 72 hours)
Use: Establish the presence and possible etiologic role of Helicobacter pylori in cases of chronic gastric ulcer, gastritis, duodenal ulcer, dyspepsia, etc
Additional Information: Helicobacter pylori has been implicated as a factor associated with chronic gastritis. The clinical significance of the organism in regard to gastric or duodenal ulcers, dyspepsia, and gastric carcinoma remains unclear.1 Other factors such as pepsin, nonsteroidal anti-inflammatory agents (NSAIDs), aspirin, ischemia, stress, alcohol, and bile salts as well as H pylori all may have a role in altering the material mucosal barrier. The relative etiologic role of H pylori remains a subject of speculation. H pylori is hypothesized to secrete products capable of degrading gastric mucin. The organism may be seen in Gram stains on imprints from tissue biopsies. In one study, imprint Gram stains performed by imprint technique on biopsies from both the antrum and fundus yielded positives in 100% of 32 culture-positive cases.2
