CPC - Radiology, Pathology and Laboratory, and Medicine - Section 2.3

Assign CPT medicine section codes for non-surgical services such as immunisations, dialysis, cardiovascular, and physical medicine procedures.

Code medicine-section services including vaccine products paired with their separate administration codes, dialysis, cardiovascular diagnostics such as ECG and echocardiography, ophthalmology, and physical medicine and rehabilitation. Recognise the timed-code rules for therapy services and the distinction between a diagnostic test and its interpretation.

In the CPT Medicine section, immunisation administration codes (90460 to 90474) and vaccine or toxoid product codes (90476 to 90749) form two separate ranges. When a clinician administers a single influenza vaccine to an established patient, how are the services reported?

90460-90474  immunisation administration
90476-90749  vaccine/toxoid products
  • AReport only the vaccine product code, because the administration work is already bundled into that product code.
  • BReport only the immunisation administration code, because it already accounts for the vaccine that was supplied.
  • CReport the vaccine product code together with an office visit code used in place of the administration code.
  • DReport both a vaccine product code and a separate immunisation administration code for the same encounter. Correct
A vaccine encounter requires both the product code and a separate immunisation administration code. CPT deliberately splits immunisations into two ranges so that the substance supplied and the work of administering it are each captured; neither code alone reports the full service, and payers expect one from each range.

Why A is wrong: Tempting because the product code seems to describe the whole encounter, but CPT lists administration separately, so reporting the product alone omits the billable administration service.

Why B is wrong: Tempting because the administration code captures the clinical act, but it does not identify or pay for the vaccine product itself, so the supply would go unreported.

Why C is wrong: Tempting because a visit is often present, but an evaluation and management code does not substitute for the specific immunisation administration code CPT assigns.

Why D is correct: Correct: CPT requires the product (what was given) and the administration (the act of giving it) to be reported together, one code from each range.
