CPT code 87910: CMV genotyping, nucleic acid analysis2026 Medicare lab fee · Clinical Laboratory Fee Schedule
Nucleic acid-based CMV genotype analysis characterizes viral genetic material and is reported for laboratory testing that determines the cytomegalovirus genotype.
Medicare pays $257.45 for 87910 under the 2026 Clinical Laboratory Fee Schedule: one national amount, the same in every state and setting.

What 87910 covers
87910 identifies nucleic acid-based genotype analysis of cytomegalovirus (CMV). A molecular laboratory examines CMV genetic material to characterize the virus’s genotype. This differs from testing that detects CMV or measures viral load: genotype analysis addresses genetic characteristics, not the amount of virus. The code identifies CMV as the infectious agent, so genotype codes for other agents are not substitutes for this service.
Report 87910 for the CMV genotype analysis performed. Medicare pays it through the CLFS at one national amount per code across all states and localities, without geographic adjustment or an office-versus-facility difference. The 2026 national CLFS amount is $257.45 and has remained unchanged since 2020. The test is excluded from the physician fee schedule and is paid only through the CLFS.

How Medicare pays 87910
Clinical lab tests aren’t priced like physician services. They’re paid from their own fee schedule, with its own rules. See the whole lab fee schedule.
One national amount
CMS sets a single Clinical Laboratory Fee Schedule amount for 87910. There’s no geographic (GPCI) adjustment, so it pays the same in every state and payment locality.
No office or facility rate
Lab tests aren’t built from relative value units, so there’s no office and facility split: the place of service doesn’t change the CLFS amount.
Updated every quarter
CMS republishes the CLFS each quarter. New tests, often proprietary laboratory analyses (PLA codes), join during the year; existing amounts are updated each January.
Excluded from the physician fee schedule
The physician fee schedule lists 87910 with status X (excluded by statute), so the test itself is paid only from the CLFS.

87910 billing questions
What does 87910 analyze?
It reports nucleic acid-based genotype analysis of cytomegalovirus. The analysis characterizes CMV genetic material rather than measuring the amount of virus.
How does 87910 differ from a CMV viral-load test?
87910 characterizes CMV genotype. A viral-load test measures the amount of CMV in a specimen.
How does 87910 differ from code 87900?
87910 is CMV genotype analysis by nucleic acid. Code 87900 describes infectious-agent drug phenotype analysis.
How does Medicare pay for 87910?
Medicare pays it through the CLFS at one national amount per code, with no geographic or office-versus-facility adjustment.
Should 87910 be used for genotype analysis of other infectious agents?
No. 87910 is specific to CMV; use the applicable code for another infectious agent’s genotype analysis.
Where this amount comes from
FeeBase reads lab amounts directly from the CMS Clinical Laboratory Fee Schedule file for the quarter: one row per code, with its payment indicator and national amount. Contractor-priced tests are labeled, never given a made-up amount. Amounts are Medicare payment limits, not a patient’s bill or a commercial rate.
