Medicare Claims Processing Manual (Pub. 100-04), Ch. 17 § 30
A/B MAC (B) Distribution of Limit Amounts
30 - A/B MAC (B) Distribution of Limit Amounts
(Rev. 1, 10-01-03)
The A/B MACs (A) get drug prices from the A/B MAC (B) for drugs not listed on the SDP.
A/B MACs (B) prepare a list of the drug payment allowance limits updates (or new file depending upon
local requirements) to the claims system.
A/B MACs (B) distribute, free of charge, the updated limits in an agreed upon format directly to the
A/B MACs (A) in their jurisdiction.
A/B MACs (B) should contact each A/B MAC (A) to determine the preferred method of transmission.
A/B MACs (B) are to send this information to all A/B MACs (A) they routinely deal with. If this
method of obtaining payment allowance updates does not work for any A/B MAC (A), the A/B MAC
(B) must contact the appropriate RO office.
