Payer Timely Filing Cheat Sheet 2026: Aetna, Cigna, UHC, BCBS, and Humana Compared

How to build and maintain a reliable timely filing reference across major payers, and why a single static cheat sheet eventually becomes a liability.

Published September 2, 2026

Why a Static Cheat Sheet Eventually Backfires

Every billing team wants a single reference table listing each major payer's timely filing and appeal deadlines side by side — and that instinct is right. The risk is treating that table as permanent once it's built. Payer deadlines change periodically, vary by plan type within the same payer, and vary by affiliate for payers like BCBS. A cheat sheet built once and never revisited tends to quietly drift out of date, and nobody notices until a deadline is missed.

What a Reliable Version of This Looks Like

Rather than a single number per payer, a more durable structure breaks each payer down by plan type (commercial, Medicare Advantage, Medicaid managed care) and, where relevant, by affiliate or region — with each entry sourced from that specific plan's current provider manual, and a review date noted so staff know how fresh the information is. Rebuilding or re-verifying this quarterly is a reasonable cadence given how often plan terms shift.

The Comparison That Actually Matters Operationally

For day-to-day triage, what matters most isn't memorizing every payer's exact number of days — it's knowing, at a glance, which payers in your book of business have comparatively shorter windows and therefore need faster intake handling. Sorting your internal reference by shortest-to-longest deadline, rather than alphabetically by payer name, tends to be more operationally useful.

Building This Into Daily Workflow

The teams that get the most value from a payer deadline reference aren't the ones with the most detailed spreadsheet — they're the ones who've built a habit of checking it (or having it checked automatically) the moment a denial arrives, rather than relying on memory under time pressure.

ResolveRCM tracks deadlines by payer, plan type, and affiliate automatically and flags shorter-window claims for priority handling — no spreadsheet maintenance required. Learn more.
