What is the DD2642 form?
DD Form 2642 is the TRICARE claim form — the document TFL beneficiaries file with Wisconsin Physicians Service to get reimbursed after paying out of pocket, attaching the itemized bill and any other payer's explanation of benefits, within one year of the date of service.
When it enters your life
With Original Medicare, almost never — claims cross over to TFL automatically. The form appears when the chain breaks: a provider who can't bill TFL (most often under a Medicare Advantage pairing), overseas care where you paid up front, or an unusual billing setup. You pay at the point of service, then claim it back.
Filing it right the first time
Download the current form from esd.whs.mil or tricare.mil, attach the itemized bill (provider, dates, codes, charges) and the other payer's EOB, and send it to WPS — then track status at tricare4u.com or 866-773-0404. The clock is the unforgiving part: one year from the service date, not the bill date. Photograph receipts the day you pay and the form takes ten minutes; the claims guide has the full directory.
