Summary & Overview
CPT 0415U: Vascular Inflammation Biomarker Panel with 5-Year ACS Risk Score
CPT code 0415U is a Proprietary Laboratory Analyses (PLA) code assigned to SmartHealth Vascular Dx™ from Morningstar Laboratories LLC. The assay measures seven vascular inflammation biomarkers in a blood specimen and applies an algorithm that integrates biomarker levels with clinical factors to produce a five‑year acute coronary syndrome (ACS) risk score. As a PLA code, 0415U represents a single, manufacturer‑specific test and is relevant for labs, payers, and clinicians managing cardiovascular risk assessment.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides national context on clinical utility, coding and billing considerations for PLA tests, typical sites of service, and payer policies affecting access.
Readers will learn the clinical purpose of the test, service type and typical site of service, payer coverage landscape, and common billing modifiers associated with molecular and lab-based services. The summary highlights where data is available and notes when specific inputs are not provided. This information supports coding accuracy, claims submission, and stakeholder understanding of how a proprietary, algorithm‑driven vascular inflammation panel is represented in billing systems.
Billing Code Overview
CPT code 0415U is a Proprietary Laboratory Analyses (PLA) code specific to a single manufacturer's test. Report 0415U only for SmartHealth Vascular Dx™ from Morningstar Laboratories LLC. The test analyzes a blood specimen to measure seven biomarkers of vascular inflammation and combines those results with patient clinical factors using an algorithm to generate a five‑year risk score for acute coronary syndrome (ACS).
Service type: Proprietary laboratory molecular/biomarker panel with algorithmic risk scoring.
Typical site of service: Clinical laboratory or reference laboratory setting where blood specimens are collected in outpatient or ambulatory settings and processed by Morningstar Laboratories LLC.
Clinical & Coding Specifications
Clinical Context
A 58-year-old male with multiple cardiovascular risk factors (hypertension, hyperlipidemia, and a family history of premature coronary artery disease) presents to his primary care physician for cardiovascular risk stratification. The clinician orders the SmartHealth Vascular Dx™ test (0415U) to assess vascular inflammation markers from a venous blood specimen. The patient has blood drawn in an outpatient phlebotomy suite; the specimen is processed and sent to Morningstar Laboratories LLC. The laboratory performs biomarker assays for seven inflammatory proteins, runs the proprietary algorithm combining biomarker levels with documented clinical factors (age, sex, known risk conditions), and returns a five-year acute coronary syndrome (ACS) risk score to the ordering provider. The provider reviews the report during a follow-up visit or via the electronic health record, integrates the risk score into the broader clinical assessment, and documents the test order, specimen collection, laboratory result, and clinical interpretation in the medical record.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when reporting only the professional interpretation portion if separate from the laboratory technical component and permitted by the payor. |
TC | Technical component | Use when reporting only the laboratory technical component (assay processing) if separated from professional component. |
QK | CLIA waived test performed by a non-laboratory practitioner | Use if qualifying conditions apply and the performer meets the CLIA requirements for the waived test (rare for PLA tests). |
QX | CLIA moderate complexity testing performed by a non-laboratory practitioner | Use if a moderate complexity portion is performed and meets CLIA rules for personnel. |
QY | CLIA high complexity testing performed by a non-laboratory practitioner | Use only if high-complexity testing personnel rules apply (generally not applicable to proprietary reference lab testing). |
62 | Two surgeons | Use if two physicians of different specialties share performance responsibilities when applicable to specimen collection procedures requiring separate surgical services. |
78 | Unplanned return to the operating/procedure room for a related procedure during the postoperative period | Use only when a related procedural re-entry occurs; rarely applicable for diagnostic lab testing but included for completeness. |
80 | Assistant surgeon | Use when an assistant surgeon is documented for an associated procedure requiring assistance (rare for blood specimen collection). |
82 | Assistant surgeon (when qualified resident not available) | Use as above when a qualified resident is not available. |
52 | Reduced services | Use when the laboratory or provider documents that services were reduced or partially performed. |
53 | Discontinued procedure | Use when specimen collection or test processing was discontinued and properly documented. |
22 | Increased procedural services | Use when substantially greater work is documented for the service (uncommon for standardized lab assays). |
23 | Unusual anesthesia | Use when unusual anesthesia is required for a related procedure; not typical for routine blood draws. |
55 | Separation of physician/surgeon services | Use when another physician assumes postoperative management for a related procedure. |
