CPT 83722: Direct Measurement of Small Dense LDL Cholesterol
CPT code 83722 designates a laboratory test that directly measures small dense low–density lipoprotein (LDL) cholesterol in a patient specimen. The measure provides a more specific assessment of atherogenic LDL subfractions than standard LDL-C and can be used in clinical risk stratification and management of patients with dyslipidemia. Nationally, advanced lipid testing like this contributes to targeted preventive cardiology and precision risk assessment, with implications for laboratory service utilization and coverage policy.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for 83722, typical sites where the service is performed, and the relevance of direct small dense LDL measurement to patient management. The publication outlines billing and coding considerations, common modifiers, and what information is available for payers and coverage practices. Where input data is incomplete, the summary notes that specific taxonomy, diagnosis linkage, and related-code details are not available in the input.
