What 84153 covers

This laboratory assay measures total prostate-specific antigen (PSA) in a blood specimen, typically serum. Primary care clinicians and urologists may order it when evaluating prostate-related symptoms or findings and when monitoring a patient with prostate cancer. The result measures total PSA rather than separating the free and protein-bound fractions. A laboratory reports the assay result to the ordering clinician for interpretation alongside the patient’s clinical context and other findings.

Report 84153 for the total PSA assay, generally as one unit for one specimen tested. When a separate free PSA assay is performed, it is reported separately with 84154. Medicare pays 84153 from the Clinical Laboratory Fee Schedule (CLFS), not the physician fee schedule. The 2026 national CLFS amount is $18.39 and has remained unchanged from 2020 through 2026. The same amount applies across states and localities, without a geographic adjustment or office-versus-facility difference.

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 84153

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 84153. 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 84153 with status X (excluded by statute), so the test itself is paid only from the CLFS.

84153 billing questions

When should 84153 be reported instead of 84154?

Report 84153 for measurement of total PSA. Report 84154 when the laboratory performs a separate free PSA assay.

How does 84153 differ from 84152?

84153 measures total PSA, while 84152 measures complexed PSA. Select the code that matches the fraction measured by the assay.

How many units are typically reported?

Typically, report one unit for one total PSA assay on a specimen. The code represents the total PSA measurement, not separate units for PSA fractions.

Is a physician interpretation separately paid with 84153?

Medicare pays 84153 through the CLFS. The code is excluded from the physician fee schedule, so it does not carry a separately payable physician interpretation component under that schedule.

Does Medicare use a different 84153 amount by locality or setting?

No. Medicare uses one national CLFS amount for the code across localities, without an office-versus-facility difference.
