Summary & Overview
CPT 0440U: PrecisionCHD Proprietary Molecular Diagnostic Assay for CHD
Headline: New PLA Code for PrecisionCHD™ Flags Proprietary Molecular Test for Coronary Heart Disease
Lead: CPT code 0440U designates a proprietary laboratory assay — PrecisionCHD™ from Cardio Diagnostics Inc. — that uses whole‑blood qPCR and digital PCR to evaluate 10 SNPs and six DNA methylation markers and reports an algorithmic result of detected or not detected for coronary heart disease. The code formalizes billing for this single‑manufacturer test and has implications for laboratory reimbursement, payer coverage policies, and clinical adoption.
Why it matters nationally: Proprietary laboratory analyses increasingly shape precision medicine pathways; a unique CPT code like 0440U allows clearer identification of utilization and reimbursement for a specific commercial CHD risk test across payers. Stakeholders will monitor coverage decisions and claims coding consistency as adoption evolves.
Key payers covered: Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: This publication provides benchmarks for payer coverage and reimbursement practices, summarizes clinical context for a genomic/epigenetic CHD assay, outlines coding and billing considerations associated with a PLA code, and highlights policy and utilization questions payers and providers may address. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 0440U is a Proprietary Laboratory Analyses (PLA) code that applies only to a single, manufacturer-specific test: PrecisionCHD™ from Cardio Diagnostics Inc. The test analyzes a whole‑blood sample using quantitative polymerase chain reaction (qPCR) and digital PCR to assess 10 single‑nucleotide polymorphisms (SNPs) and six DNA methylation markers in specified genes. An algorithmic analysis generates a result reported as detected or not detected for coronary heart disease (CHD).
Service type: Genetic/epigenetic molecular diagnostic test (proprietary laboratory assay)
Typical site of service: Clinical laboratory or reference laboratory using whole‑blood collection

Clinical & Coding Specifications
Clinical Context
A 55-year-old patient with intermediate clinical risk factors for coronary heart disease (CHD) presents to a primary care clinic concerned about future cardiovascular risk. The clinician performs a cardiovascular risk assessment and, after discussion of testing options, orders the PrecisionCHD™ test (0440U) to refine risk stratification. A whole-blood sample is collected in the outpatient clinic or a specimen collection center and sent to the performing laboratory. The lab performs quantitative polymerase chain reaction (qPCR) and digital PCR analysis of 10 single–nucleotide polymorphisms and six DNA methylation markers, then applies the proprietary algorithm to generate a detected/not detected result for CHD. The lab report is returned electronically to the ordering clinician, who documents the result in the medical record, incorporates it into the patient’s risk profile, and communicates findings and follow-up plans to the patient. Typical sites of service include outpatient physician offices, ambulatory collection centers, and clinical laboratories. Common payer interactions include prior authorization review and claims submission under the Proprietary Laboratory Analyses (PLA) code 0440U with applicable modifiers such as 00, 22, 52, or 53 when appropriate.
