Summary & Overview
CPT 87075: Bacterial Culture, Excluding Blood Specimens
CPT code 87075 represents the laboratory procedure for culturing bacteria from clinical specimens, excluding blood. This code is a cornerstone in microbiology diagnostics, enabling healthcare providers to identify bacterial pathogens and inform treatment decisions. The procedure is commonly performed in laboratory settings and is vital for managing infections such as pharyngitis, pneumonia, abscesses, urinary tract infections, and other bacterial conditions.
Major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare provide coverage for this service, reflecting its widespread clinical importance. Readers will gain insight into payer coverage policies, relevant modifiers such as 26 and TC, associated taxonomies, and common ICD-10 diagnoses linked to this procedure. The publication also highlights related CPT codes for bacterial culture and identification, offering a comprehensive view of microbiology billing practices.
This summary provides an overview of benchmarks, policy updates, and clinical context for CPT code 87075, supporting laboratory and clinical teams in understanding the role and reimbursement landscape of bacterial culture services.
CPT Code Overview
CPT code 87075 is used to report the laboratory procedure for culturing bacteria, except those found in blood specimens. This service falls under Microbiology Culture and Typing Procedures, which are essential for identifying bacterial pathogens in clinical samples. The typical site of service for this procedure is a laboratory setting, specifically at Place of Service 19. Bacterial cultures play a critical role in guiding appropriate treatment and infection control measures across a wide range of clinical scenarios.
Clinical & Coding Specifications
Clinical Context
A patient presents to a clinic with symptoms suggestive of a bacterial infection, such as sore throat, cough, skin abscess, or urinary discomfort. The provider collects a specimen (e.g., throat swab, wound swab, urine sample) and sends it to the laboratory for bacterial culture. The laboratory performs the procedure described by CPT code 87075 (Culture bacteria, except blood) to identify the presence and type of bacteria in the sample. Results guide further clinical management, including targeted antibiotic therapy. The service is typically performed in a laboratory setting (Place of Service 19).
