Billing code 76145: Dose evaluationMedicare rate & RVUs in Texas
A medical physicist evaluates radiation exposure from diagnostic imaging or radiation therapy, typically when an event requires a focused dose assessment.
Medicare pays $945.91–$1,096.44 for 76145 in the office in Texas, from Beaumont to Austin. Which amount applies depends on the service address.
Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 76145 covers
A medical physicist reconstructs or evaluates the radiation dose associated with a specific exposure, using relevant imaging or treatment details and patient information. The service may follow a concern about an unusual or unintended exposure from a CT examination, another diagnostic imaging procedure, or radiation therapy. It is a focused physics evaluation, not the routine dose calculation performed as part of ordinary imaging or treatment planning.
Report this code for the technical dose-evaluation work, supported by documentation identifying the exposure and the data reviewed or used in the assessment. The CMS physician fee schedule classifies it as technical-component-only: a separate code covers interpretation. Keep the technical evaluation distinct from the clinical interpretation and document the resulting dose assessment or report. The supplied CMS rules identify no add-on, global-period, or multiple-procedure payment instruction for this code.

How to choose
- 76140X-ray consultation
- 76140 is for consultation and interpretation of an x-ray examination made elsewhere. Use 76145 for a physicist’s technical evaluation of radiation dose from an exposure.
- 77370Radiation physics consult
- 77370 describes a special medical radiation physics consultation in radiation therapy. It is distinct from a focused evaluation of dose associated with a radiation exposure.
- 77300Dosimetry calculation
- 77300 is a basic radiation dosimetry calculation for treatment planning. 76145 evaluates dose associated with an exposure, such as an unusual or unintended one.
76145 billing questions
How is this different from an x-ray consultation?
This code represents a medical physicist’s evaluation of radiation dose from an exposure. An x-ray consultation concerns interpretation of an imaging examination made elsewhere.
Is the interpretation included in this code?
No. CMS classifies this as technical-component-only; a separate code covers interpretation.
Is routine imaging dose monitoring reported with this code?
The service is a focused evaluation of a specific exposure, rather than routine dose calculation or monitoring performed as part of ordinary imaging.
What documentation supports reporting it?
Document the exposure being evaluated, the relevant imaging or treatment information reviewed, and the physicist’s dose assessment.
How does this differ from a radiation therapy physics consultation?
This code addresses evaluation of radiation exposure. A special medical radiation physics consultation concerns a physics problem associated with radiation therapy care.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
