85130 Chromogenic substrate assay
Also known as: chromogenic assay, chromogenic substrate test
Coagulation assay using chromogenic substrate methodology where peptide substrate linked to chromophore is cleaved by coagulation enzymes, producing color change proportional to enzyme activity.
In Plain Language
color-change clotting test; enzyme activity test
Clinical Context
Measures specific coagulation factors or inhibitors with superior specificity to traditional methods; useful for heparin monitoring, factor assays, and inhibitor detection.
RVU Information
CPT 85130 does not have a physician work RVU assigned by CMS. Reimbursement for this code is determined by payer-specific fee schedules.
Billing & Documentation
Lab and pathology codes require an order from the treating provider with clinical indication. For molecular pathology and genetic testing, document the specific analytes tested and clinical rationale.
How This Code Compares
This code has a work RVU of 0.00, meaning it does not have a physician work component assigned by CMS. In the Pathology & Lab category, 94% of codes share this characteristic.
