Result: Medicare: file within 365 days of service; deadline 2027-03-01.
The tool opens with these values already filled in. Replace them with your own.
What you enter
- Date of service (YYYY-MM-DD)
- Payer: medicare (365 days by 42 CFR 424.44) or other, whose limit you supply
- Plan filing limit in days, for a non-Medicare payer.
Full field descriptions
- Plan filing limit in days, for a non-Medicare payer. Medicare is one calendar year by 42 CFR 424.44 and this does not override it; a value given alongside medicare is reported back as unused.
How this is calculated
42 CFR 424.44: Medicare claims must be filed within one calendar year (365 days) after the date of service (ACA 6404). Medicaid and commercial limits vary and are user-supplied, not shipped as a directory. Read the source ↗
