CPT Code Overview

CPT code 87070 is used to report a bacterial culture from any source except urine, blood, or stool. This procedure involves the isolation and presumptive identification of bacterial isolates from clinical specimens, supporting the diagnosis and management of infectious diseases. The service falls under Microbiology/Pathology – Laboratory Procedures and is typically performed in a laboratory setting, such as Place of Service 19. This code is essential for clinicians seeking to identify bacterial pathogens from a variety of specimen types, enabling targeted treatment and infection control.

Clinical & Coding Specifications

Clinical Context

A patient presents to a clinic with symptoms such as sore throat, fever, or skin infection. The provider suspects a bacterial infection and collects a specimen from a source other than urine, blood, or stool (e.g., throat swab, wound swab, or skin lesion). The specimen is sent to the laboratory for aerobic bacterial culture using CPT code 87070. The laboratory isolates and presumptively identifies any bacterial organisms present. Results are reported to the provider to guide further clinical management, such as antibiotic selection.

Coding Specifications

Modifier 26: Used to indicate the professional component of the laboratory service, typically when a physician or pathologist interprets the results.
Modifier 59: Used to denote a distinct procedural service, such as when multiple cultures are performed from different sites or when the procedure is separate from other laboratory services.
