What 83002 covers
This laboratory assay measures luteinizing hormone (LH), a pituitary hormone involved in reproductive function. It is generally performed on a blood sample, usually serum. Clinicians order it when evaluating infertility, irregular or absent menstruation, suspected ovulatory disorders, delayed or early puberty, hypogonadism, or possible pituitary or gonadal dysfunction. Results are interpreted with the patient’s clinical findings and may be considered alongside follicle-stimulating hormone (FSH), estradiol, or testosterone measurements.
Report 83002 for the LH assay performed; use the separate FSH code when that hormone is also tested. CMS lists modifier QW for the CLIA-waived version performed by a site holding a CLIA certificate of waiver. Medicare pays this test only through the CLFS. The 2026 national amount is $18.52, unchanged since 2020, and applies nationwide without locality or office/facility variation.

How Medicare pays 83002
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 83002. 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 83002 with status X (excluded by statute), so the test itself is paid only from the CLFS.
CLIA-waived version (QW)
CMS also lists 83002 with modifier QW, the version labs holding a CLIA certificate of waiver bill. It pays $18.52.

- 83001FSH testFollicle-stimulating hormone$18.58
- Choose 83002 for LH and 83001 for FSH. The hormones may be ordered together, but each assay has its own code.
- 82670EstradiolTotal estradiol$27.94
- 82670 measures estradiol, not a pituitary gonadotropin. Use 83002 when the test performed measures LH.
- 84403TestosteroneTotal hormone level$25.81
- 84403 measures testosterone. It is not a substitute for an LH assay, although both may be used in a gonadal evaluation.
83002 billing questions
How is 83002 different from the FSH assay?
83002 measures luteinizing hormone. Use 83001 for follicle-stimulating hormone; both may be ordered during a reproductive or gonadal evaluation.
What specimen is used for an LH assay?
The assay is generally performed on a blood sample, usually serum.
When is modifier QW appropriate?
CMS lists QW for the CLIA-waived version of this test. Use it when the waived test is performed by a site holding a CLIA certificate of waiver.
Can LH and FSH assays be reported together?
Yes. Report 83002 for LH and 83001 for FSH when both assays are performed.
How does Medicare price 83002?
Medicare pays one national CLFS amount for the code, with the same amount across localities and office and facility settings.
