CPT code 87910 represents a molecular diagnostic laboratory test: the technical laboratory analysis of cytomegalovirus (CMV) genotype using nucleic acid methods. This code is used when laboratory personnel perform the technical component of CMV genotyping to characterize viral genetic variants. CMV genotype testing supports clinical care in immunocompromised patients, transplant recipients, and neonates, and informs infection management, resistance surveillance, and public health tracking.

Key payers considered in national coverage and reimbursement contexts include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage policies and payment rates for CMV genotyping can vary by payer and setting; readers should expect differences in lab reimbursement, prior authorization requirements, and medical necessity criteria among commercial plans and Medicare.

This publication provides an overview of CPT code 87910, including clinical context for CMV genotyping, typical sites of service, payer coverage landscape, and the kinds of benchmarks and policy details readers will find in the full report. The full content addresses reimbursement benchmarks, common modifier use and billing considerations, and clinical scenarios where CMV genotyping is applied. Data not available in the input is noted where specific payer policy details, associated taxonomies, and related codes would otherwise be listed.
