What 83701 covers
83701 identifies high-resolution fractionation and quantitation of lipoproteins in blood, including subclasses when performed. A laboratory may separate lipoproteins by methods such as electrophoresis or ultracentrifugation and report the resulting fractions. The test provides detailed lipoprotein characterization beyond a single cholesterol assay and may be ordered when evaluating lipid abnormalities or cardiovascular risk. It is distinct from an assay that reports one HDL- or LDL-cholesterol result.
Subclasses measured as part of the analysis are included in the 83701 service, not separate 83701 services. Medicare pays this laboratory test through the CLFS only. The 2026 national CLFS amount is $33.86 and has remained unchanged since 2020. One amount applies in every state and locality, without geographic or office-versus-facility adjustment.
This summary was written with AI assistance from CMS Clinical Laboratory Fee Schedule data. Amounts on this page come directly from CMS files.
How Medicare pays 83701
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 83701. 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 83701 with status X (excluded by statute), so the test itself is paid only from the CLFS.

83701 compared with similar tests
- 83700Lipoprotein testElectrophoretic separation$11.26
- 83700 reports electrophoretic lipoprotein testing. Choose 83701 when the service performs high-resolution fractionation and quantitation, including subclasses when performed.
- 83704Lipoprotein particlesParticle-number quantitation$34.19
- 83704 quantifies lipoprotein particles; 83701 characterizes lipoprotein fractions and subclasses.
- 83718HDL cholesterolDirect measurement$8.19
- 83718 measures HDL cholesterol. It is a single-analyte assay, not high-resolution lipoprotein fractionation.
- 83721LDL cholesterolDirect LDL measurement$10.50
- 83721 directly measures LDL cholesterol. It is not the high-resolution lipoprotein fractionation reported with 83701.
83701 billing questions
When should 83701 be selected instead of 83700?
Select 83701 for high-resolution fractionation and quantitation, including subclasses when performed. Code 83700 describes electrophoretic lipoprotein testing.
How does 83701 differ from 83704?
83701 reports high-resolution lipoprotein fractions, including subclasses when performed. 83704 is used for lipoprotein particle quantitation.
Are measured subclasses billed as separate 83701 services?
No. Subclasses measured as part of the high-resolution fractionation are included in the 83701 service.
What specimen is tested?
83701 is a blood lipoprotein test.
How does Medicare pay 83701?
Medicare pays 83701 through the CLFS only. The national amount applies across localities and does not vary by office or facility setting.
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.
