Summary & Overview
CPT 82085: Aldolase Quantitative Assay, Serum
CPT code 82085 denotes a quantitative laboratory assay for the enzyme aldolase, commonly performed on serum to measure enzyme concentration. This test has clinical relevance in the evaluation of muscle injury, myopathies, and certain systemic conditions where aldolase levels may assist diagnosis or monitoring. Nationally, accurate coding ensures appropriate laboratory billing, clinical documentation, and aggregation of utilization data for surveillance of muscle-related disorders.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides readers with a concise view of coding context, payer coverage considerations, typical sites of service, and the clinical role of the assay.
Readers will learn what CPT code 82085 represents, common clinical indications for aldolase quantitation, how the service is typically delivered (laboratory/hospital laboratory with serum specimens), and which major payers are relevant for coverage discussions. The report also outlines typical operational and billing contexts for the assay and notes where input data are not available. Data not available in the input: associated taxonomies, ICD-10 diagnoses, related codes, and payer-specific reimbursement benchmarks.
Billing Code Overview
CPT code 82085 describes a laboratory quantitation of the enzyme aldolase, measuring the amount of the analyte present in a patient specimen. The procedure is typically performed by a clinical laboratory analyst using serum as the usual specimen source.
Service type: Laboratory test — quantitative enzymatic assay
Typical site of service: Clinical laboratory or hospital laboratory (serum specimen collection)
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting with progressive proximal muscle weakness, myalgias, and elevated serum muscle enzymes. The clinician orders a serum aldolase quantitation to help evaluate muscle injury or inflammatory myopathy. A phlebotomy technician draws a serum sample in an outpatient clinic or hospital laboratory; the specimen is transported to the clinical laboratory where a medical laboratory scientist or technologist performs the quantitative aldolase assay using enzymatic or automated analyzer methods. Results are reviewed by the laboratory director and reported to the ordering clinician to assist in diagnosis and monitoring of conditions such as polymyositis, dermatomyositis, muscular dystrophy, or other causes of myonecrosis. Typical sites of service include hospital outpatient laboratory, independent clinical laboratory, and hospital inpatient laboratory. Turnaround time may vary from stat (urgent) to routine depending on clinical urgency and lab workflow.
