What A9512 covers
Technetium-99m pertechnetate is a diagnostic radiopharmaceutical used in nuclear medicine imaging. It is taken up by the thyroid, salivary glands, and gastric mucosa; typical studies include thyroid or salivary gland imaging and evaluation for ectopic gastric mucosa, such as a Meckel diverticulum. Nuclear medicine teams administer the agent, commonly by intravenous injection. The radiopharmaceutical line identifies the drug and dose, while the imaging procedure is reported under its applicable procedure code.
A9512 is reported per millicurie: one unit represents 1 mCi of technetium-99m pertechnetate. Medicare assigns it Physician Fee Schedule status C, or carrier priced. The Medicare Administrative Contractor sets payment for each claim; HCPCS pricing also assigns payment to other contractor pricing. Coverage is left to the Medicare contractor’s judgment.

A9512 billing questions
What does one unit of A9512 represent?
One unit represents 1 mCi of technetium-99m pertechnetate. Report units based on the administered dose documented in millicuries.
When is A9512 used instead of an iodine-123 sodium iodide code?
A9512 identifies technetium-99m pertechnetate. A9509 and A9516 identify iodine-123 sodium iodide, billed per millicurie and per microcurie, respectively; select the code matching the agent and unit amount.
Does A9512 represent the imaging procedure?
No. A9512 identifies the radiopharmaceutical and its dose. Thyroid imaging services may be reported with the applicable procedure code, such as 78013 or 78014.
How does Medicare price A9512?
Its Physician Fee Schedule status is C, or carrier priced. The Medicare contractor sets payment for each claim, and coverage is left to that contractor’s judgment.
What dose documentation supports the units?
Document the radiopharmaceutical’s identity and the administered dose in millicuries so the A9512 units reflect the dose given.
