Original Medicare (fee-for-service)
Initial claims
12 months
“the claim must be filed no later than the close of the period ending 1 calendar year after the date of service” (42 CFR § 424.44(a)(1)) — with narrow exceptions in (b) (administrative error, retroactive Medicare entitlement, Medicaid recoupment, retroactive MA/PACE disenrollment) and a non-workday rollover in (c)

No appeal level was extracted for this payer this pass — an extraction gap, not a statement that no appeal process exists.
Original Medicare states this window in months and the calculator counts calendar days, so there is no preset for it — pick another payer's window or enter the day count your contract uses.
Date of service plus the payer's filing window, in calendar days. Estimate only — the payer's contract wording controls.
Enter a date of service to compute the deadline.
Deadline = date of service + the filing window in calendar days; days left counts from your device's date today. This tool counts calendar days. Payer contracts may count differently — some windows run in months, from the end of the month of service, or from the date the payer received the claim — so treat the result as a planning estimate and confirm the payer's own contract wording. Windows outside 30–730 days are clamped, and a date of service more than a year ahead is rejected as a likely typo. Payer windows in the list carry the payer's published figure; the cited source appears on that payer's page.
