CPT 87152 Pulse Field Gel Typing Reimbursement

CPT code 87152 designates a pulse field gel electrophoresis (PFGE) analysis performed on a previously isolated and identified organism to achieve higher-resolution taxonomic typing. The procedure supports public health surveillance, outbreak investigation, and detailed laboratory characterization of microbial strains, making it a nationally relevant code for clinical and public health laboratories.

Key payers in coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for PFGE-based typing, typical sites of service, common billing modifiers, and payer coverage considerations. The publication outlines benchmarking metrics and policy-relevant updates that affect reimbursement and billing practice for specialized microbiology testing. It also explains operational and documentation implications for laboratories submitting claims under this CPT code, and highlights areas where payers commonly request additional clinical or laboratory documentation.

The report is intended for laboratory managers, billing professionals, and policy analysts seeking a concise reference on CPT code 87152, its clinical role, and the payer landscape affecting coverage and claims handling.

Billing Code Overview

CPT code 87152 describes a laboratory analysis performed by a lab analyst using a pulse field gel electrophoresis (PFGE) technique on a previously isolated and identified organism to categorize the organism more specifically, such as to the taxonomic level of type. The service is a specialized microbiology molecular typing procedure used to differentiate strains of microorganisms for epidemiology, outbreak investigation, and laboratory characterization.

Service type: Specialized microbiology molecular typing using PFGE
Typical site of service: Clinical microbiology laboratory or public health laboratory

Clinical Context

A 56-year-old patient with recurrent hospital-associated methicillin-resistant Staphylococcus aureus (MRSA) infections has an isolate sent to the clinical microbiology laboratory after culture and primary identification. The laboratory performs a pulse field gel electrophoresis (PFGE) analysis to subtype the previously isolated and identified organism to the strain or type level for epidemiologic typing, outbreak investigation, or infection-control tracking. Workflow: the specimen is cultured and the organism is isolated and preliminarily identified (routine culture, biochemical testing or MALDI-TOF). The isolate is then accepted into the molecular epidemiology lab, DNA is extracted, restriction enzyme digestion is performed, and PFGE gels are run, imaged, and analyzed. Results are reported to the hospital infection prevention team, the ordering clinician, and, when required, public health authorities for cluster assessment or surveillance.
