Summary & Overview
CPT 83002: Luteinizing Hormone Assay, Serum
CPT code 83002 designates a laboratory assay that measures luteinizing hormone (LH) in serum, an endocrine marker central to reproductive and gonadal function. The test is commonly ordered to evaluate causes of ovulatory dysfunction in females and disorders of testosterone production or hypogonadism in males. As a standardized clinical laboratory procedure, CPT code 83002 is widely used across outpatient and hospital laboratory settings and factors into diagnostic pathways for infertility, amenorrhea, delayed or precocious puberty, and certain endocrine disorders.
Payors covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise summary of the clinical context for ordering the assay, the typical service setting, and how the code relates to related endocrine testing. The publication provides benchmarks and payment context where available, notes common clinical indications, and highlights coding relationships to other laboratory hormone assays. This material is intended for billing professionals, laboratory managers, and clinicians who need a clear reference to the clinical purpose and administrative handling of CPT code 83002.
Billing Code Overview
CPT code 83002 measures the concentration of luteinizing hormone (LH) in a serum specimen. LH is a pituitary-derived gonadotropic hormone that regulates ovulation in females and testosterone production in males. This assay is a clinical laboratory service performed by trained laboratory analysts.
Service type: Clinical laboratory test — endocrine hormone assay
Typical site of service: Clinical laboratory or hospital laboratory, with specimens collected in outpatient clinics or inpatient settings
Clinical & Coding Specifications
Clinical Context
A 34-year-old female presents to her primary care clinic with irregular menses and difficulty conceiving for 8 months. She reports intermittent fatigue and recent mood changes. The clinician orders a serum luteinizing hormone assay to evaluate pituitary-gonadal axis function and determine ovulatory status. A phlebotomy technician collects a serum specimen in the outpatient laboratory; the specimen is transported to the clinical medical laboratory where a lab analyst performs quantitative measurement of luteinizing hormone using an immunoassay. Results are reported to the ordering Family Medicine physician and documented in the electronic health record. The test guides further evaluation for causes of infertility or menstrual irregularity and may be repeated during a timed cycle or compared with follicle-stimulating hormone levels.
