Medicare Claims Processing Manual (Pub. 100-04), Ch. 13 § 110.3
Payment for Radiopharmaceuticals
110.3 - Payment for Radiopharmaceuticals
(Rev. 1, 10-01-03)
Radiopharmaceuticals are not subject to the fee schedule, but are paid based on
reasonable cost when given in a SNF. SNFs report HCPCS codes 79900, A4641, A4642,
A9500, A9503, and A9505, as appropriate, with revenue codes 0333, 034X, or 0636.
NOTE: The correct code to report is A4641. It replaced HCPCS code 78990. HCPCS
code 78990 should not be reported because this code is not valid for Medicare purposes.
EXCEPTION: HCPCS codes 77781, 77782, 77783, and 77784 include payment for the
radiopharmaceutical in the technical component. When these procedures are performed,
SNFs do not report radiopharmaceutical codes 79900, A4641, A4642, A9500, A9503,
and A9505. The A/B MAC (A) will reject codes 79900, A4641, A4642, A9500, A9503,
and A9505 when they are billed for supplies used in conjunction with procedure codes
77781, 77782, 77783, and 77784.
