What 83012 covers
This laboratory assay characterizes haptoglobin phenotypes in serum rather than measuring the protein's concentration. Clinical laboratories and reference laboratories perform and report the analysis when a clinician orders phenotype information. The result distinguishes phenotype characterization from quantitative haptoglobin testing, which reports a measured level.
Report 83012 for haptoglobin phenotype analysis. Medicare pays the test through the Clinical Laboratory Fee Schedule (CLFS), which sets one national amount across states and localities, with no geographic adjustment or office-versus-facility difference. The 2026 national CLFS amount is $26.89, unchanged since 2020. The physician fee schedule classifies this test as paid only through the CLFS. Use 83010 when the ordered assay quantifies haptoglobin rather than characterizing its phenotype.

How Medicare pays 83012
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 83012. 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 83012 with status X (excluded by statute), so the test itself is paid only from the CLFS.

Medicare pays it through the CLFS at one national amount across localities, without an 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.
