CPT code 82947: Blood glucose, quantitative, not reagent strip2026 Medicare lab fee · Clinical Laboratory Fee Schedule
A quantitative blood-glucose assay used for laboratory measurement, distinct from reagent-strip testing and glucose-tolerance testing.

What 82947 covers
This assay measures the glucose concentration in blood using a quantitative laboratory method rather than a reagent strip. It is commonly ordered to evaluate or monitor hyperglycemia, hypoglycemia, and diabetes, and may be performed by a clinical laboratory or in a physician’s office. When glucose is included in a chemistry panel, use the panel code for that panel service rather than separately reporting the same determination.
Report the assay for the quantitative blood-glucose test performed; glucose tolerance testing and additional tolerance-test samples have separate codes. CMS lists a QW version for performance by a site holding a CLIA certificate of waiver. Medicare pays this test only through the CLFS, at one national amount that is the same across states and localities, with no office-versus-facility difference. The 2026 national CLFS amount is $3.93, unchanged each year since 2020.

How Medicare pays 82947
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 82947. 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 82947 with status X (excluded by statute), so the test itself is paid only from the CLFS.
CLIA-waived version (QW)
CMS also lists 82947 with modifier QW, the version labs holding a CLIA certificate of waiver bill. It pays $3.93.

- 82962 identifies glucose testing with a qualifying blood-glucose monitoring device. 82947 describes the quantitative assay rather than that device-based service.
- 82950Post-dose glucoseAfter glucose challenge$4.75
- 82950 is used for glucose testing after a glucose dose. Use 82947 for a standalone quantitative blood-glucose determination.

82947 billing questions
When should 82947 be used instead of a reagent-strip glucose code?
Use 82947 for a quantitative blood-glucose assay performed by a laboratory method. A reagent-strip determination is reported with 82948.
Can 82947 be reported for glucose included in a chemistry panel?
When the glucose determination is performed as part of a separately coded chemistry panel, report the panel rather than separately reporting that same determination.
When may modifier QW be used?
CMS lists a QW version for the CLIA-waived test. Use QW when the qualifying waived test is performed at a site holding a CLIA certificate of waiver.
Does 82947 describe a glucose tolerance test series?
No. Use the glucose tolerance test code for the series; 82952 is used for additional blood-glucose determinations in that testing context.
How does Medicare pay for 82947?
Medicare pays the test through the CLFS at one national amount, with the same payment across localities and no office-versus-facility difference.
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.
