What 87507 covers
This laboratory test uses multiplex nucleic acid methods to detect a broad range of gastrointestinal pathogens, such as C. difficile, pathogenic E. coli, Salmonella, Shigella, norovirus, and Giardia. It is commonly performed on stool from patients being evaluated for infectious diarrhea. Clinical laboratories and hospital laboratories typically perform and report the test; the panel is useful when the clinical question calls for testing across multiple possible infectious causes rather than a single-organism assay.
Report one unit for the panel performed on a specimen, not separate units for each target detected. Select this code for a panel covering 12–25 targets; panels with fewer targets have separate codes. Medicare pays the test only through the CLFS. The 2026 national CLFS amount is $416.78, unchanged since 2020, and the same amount applies across localities and office or facility settings. The test is excluded from the physician fee schedule.

How Medicare pays 87507
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 87507. 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 87507 with status X (excluded by statute), so the test itself is paid only from the CLFS.

87507 billing questions
When should this code be selected instead of 87506?
Use 87507 when the gastrointestinal panel covers 12–25 targets. Code 87506 is the related panel code for a smaller target range.
Are individual pathogens reported separately from the panel?
This code represents the multiplex panel, not a separate charge for each organism target. Report the panel test performed.
How many units should be reported?
Report one unit for each panel test performed on a specimen, rather than one unit per target.
How does Medicare pay for this test?
Medicare pays it through the CLFS only, at one national amount that applies across localities and office or facility settings.
How does this differ from a C. difficile-only molecular test?
This code represents a broad gastrointestinal panel with 12–25 targets. A C. difficile-specific molecular test, such as 87493, addresses that organism rather than a broad panel.
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.
