The responsibility of reviewing claims (other than SSI) and making initial determinations is divided among six program service centers, the Office of Disability Operations (ODO) and the Office of Earnings and International Operations (OEIO). As used in the POMS, the term “PSC” refers to the 6 PSC offices and OEIO. The term “processing center” refers to the 7 PSC's plus ODO. These offices review, adjudicate, and service all claims as appropriate within their jurisdiction.

The State Disability Determination Services (DDS) makes most disability determinations. For a full discussion of jurisdiction and routing procedures in disability cases, see DI 11010.255 and DI 11025.000. Instructions for railroad claims are located in RS 01602.000.

These addresses for normal forwarding of claims related material are shown below. There are special addresses for reports of nonreceipt of checks, for SMI premiums and for critical case referral.
