CPT code 80047: Basic metabolic panel, ionized calcium2026 Medicare lab fee · Clinical Laboratory Fee Schedule
This blood chemistry panel combines ionized calcium with seven other specified measurements and is reported when all eight panel tests are performed.
Medicare pays $13.73 for 80047 under the 2026 Clinical Laboratory Fee Schedule: one national amount, the same in every state and setting.

What 80047 covers
80047 represents a blood chemistry panel combining ionized calcium with carbon dioxide (bicarbonate), chloride, creatinine, glucose, potassium, sodium, and urea nitrogen. A laboratory reports the panel when all eight tests are performed. The ionized-calcium version distinguishes it from 80048, which uses total calcium. A site holding a CLIA certificate of waiver may perform the CLIA-waived version and report modifier QW.
Report one unit for the complete panel on a specimen; do not separately report the component tests when reporting the panel. Medicare pays 80047 under the CLFS at one national amount that applies across localities, without geographic or office/facility adjustment. The 2026 national amount is $13.73, unchanged from 2020 through 2026. The test is paid only through the CLFS.

How Medicare pays 80047
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 80047. 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 80047 with status X (excluded by statute), so the test itself is paid only from the CLFS.
CLIA-waived version (QW)
CMS also lists 80047 with modifier QW, the version labs holding a CLIA certificate of waiver bill. It pays $13.73.

80047 billing questions
Which tests must be included to report 80047?
The panel includes ionized calcium, carbon dioxide (bicarbonate), chloride, creatinine, glucose, potassium, sodium, and urea nitrogen. Use the panel code when all eight are performed.
How does 80047 differ from 80048?
Both are basic metabolic panels, but 80047 includes ionized calcium, while 80048 uses total calcium. Select the code that matches the calcium test performed.
When is modifier QW appropriate?
Use QW for the CLIA-waived version when the testing site holds a CLIA certificate of waiver and performs the waived test.
Can the panel components also be reported separately?
When all eight defined tests are performed as a panel, report 80047 for the panel rather than separately reporting those same components. If only some tests are performed, 80047 does not describe that subset.
How does Medicare pay 80047?
Medicare pays it through the CLFS at one national rate per code. The rate is the same across localities and does not vary between office and facility settings.
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.
