Summary & Overview
CPT 88230: Lymphocyte Tissue Culture for Nonneoplastic Disorders
CPT code 88230 identifies a laboratory tissue-culture procedure in which lymphocytes are grown to evaluate nonneoplastic (noncancerous) disorders, typically from blood specimens. This code is used nationally for diagnostic testing that informs evaluation of immune function and hematologic conditions where cultured lymphocytes are required for analysis. The procedure has implications for accurate diagnosis, laboratory workflow, and payer coverage policies across clinical laboratories and hospital labs.
Key payers discussed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for cultured lymphocyte testing, how CPT code 88230 is applied in practice, and what types of sites commonly perform the service. The publication covers benchmarks for utilization where available, relevant coding and billing considerations, and any notable policy updates affecting coverage and claims processing. The content is intended to help laboratory managers, billing professionals, and clinicians understand the code’s clinical purpose, typical sites of service, and the payer landscape for reimbursement and coding workflows.

Billing Code Overview
CPT code 88230 describes a laboratory procedure in which a lab analyst cultures lymphocytes to evaluate nonneoplastic disorders, typically using blood-derived tissue culture. The service involves growing lymphocyte cultures to assess immune cell characteristics and responses relevant to diagnosis or management of noncancerous hematologic and immunologic conditions.
Service Type: Tissue culture — lymphocyte (nonneoplastic) laboratory procedure
Typical Site of Service: Clinical laboratory or hospital laboratory
Clinical & Coding Specifications
Clinical Context
A 28-year-old patient presents to an outpatient hematology clinic with a history of recurrent unexplained lymphopenia and recurrent infections. The ordering physician requests lymphocyte culture and functional testing to evaluate for primary immunodeficiency or immune dysregulation. A phlebotomy technician collects peripheral blood; the specimen is sent to the clinical laboratory. A certified laboratory analyst performs a lymphocyte culture using peripheral blood lymphocytes to assess proliferative responses and to detect nonneoplastic lymphoid disorders. The laboratory documents specimen receipt, culture setup (including media, mitogens or antigens used), incubation conditions, monitoring for growth, and reporting of results. Results are routed to the ordering hematologist or immunologist who integrates culture findings with flow cytometry, serologies, and clinical history to guide diagnosis and management. Typical sites of service include hospital outpatient laboratories, independent clinical reference laboratories, and hospital inpatient laboratories when evaluation is performed during admission.
