Medicare Claims Processing Manual (Pub. 100-04), Ch. 3 § 80.1
Medicare Summary Notice (MSN) for Services in Hospitals That Do
80.1 - Medicare Summary Notice (MSN) for Services in Hospitals That Do
Not Charge
(Rev. 1, 10-01-03)
A3-3660.5.A
Where the hospital does not charge for outpatient services, the A/B MAC (A) does not send
the individual an MSN. This avoids confusion and the appearance that the beneficiary is
liable for services received.
