The complete 2026 reference for U.S. medical billing teams: every state’s Medicare Administrative Contractor (MAC), timely filing limits, no-fault PIP rules, and key compliance gotchas — on a single 2-page printable PDF. Built by AMS Solutions’ AAPC-certified RCM team.
Compliance Cheat Sheet
What’s inside
- All 51 jurisdictions (50 states + DC) on a single quick-reference table
- Each state’s Medicare Administrative Contractor (MAC) — Novitas, NGS, Palmetto GBA, First Coast, WPS, Noridian, CGS
- Timely filing windows for Medicare claims (most states 365 days, but Illinois is just 180)
- No-fault / PIP rules for every state — including the strict 30-day filing window in New York, Florida’s $10K PIP cap, and Michigan’s tiered post-2019 reform
- The key compliance gotcha for each state — what trips up billing teams most
- Summary of the 8 MACs and which states each covers
Why we built this
If your practice serves patients in multiple states, you interact with multiple MACs, multiple state Medicaid programs, and a different set of no-fault rules each time. The same CPT code that gets paid in Texas (Novitas) can be denied in Florida (First Coast) based on differing Local Coverage Determinations. New York requires PIP claims within 30 days. Illinois Medicare gives you 180 days to file vs. the 365-day standard elsewhere. Every state has gotchas — and your team needs them at a glance.
This cheat sheet condenses 33 years of AMS Solutions experience working with all 8 MACs into one printable reference. Hang it next to your billing workstation. Reference it before every multi-state claim.
