The Part A intermediary is a national, State, or other public or private agency or
organization which has entered into an agreement with CMS to process Medicare claims
received from providers of services. (Providers may choose to deal directly with CMS
rather than an intermediary.)
These agencies or organizations perform such administrative duties as:
Determining the reasonable cost for provider services under both Part A and Part B;
Making payments directly to providers (in certain instances Part A intermediaries
also make payments to beneficiaries);
Providing consultative services to assist hospitals, SNFs and HHA’s to maintain necessary
fiscal records and otherwise qualify as providers;
Serving as a center for, and communicating to providers, any information or instruction
furnished by CMS;
Making audits of provider records;
Helping providers with utilization review procedures;
Providing the Bureau of Quality Control and the Office of Investigations (OI) with
needed information and assistance in the investigation of claims of fraud or abuse
against the Medicare program, and, establish controls developed in conjunction with
BQC, to minimize the possibility of incorrect Medicare payments;
Making payment directly to nonprovider renal dialysis facilities under Part B.
CMS makes payment for the intermediary’s cost of administration and advances funds
such as the Government determines to be necessary and proper for carrying out the
functions covered by the contract.
The agreement to serve as an intermediary may be terminated by either the intermediary
or CMS under certain conditions specified in the Act and in regulations.
