The Minus 30 Calculator
Every state has a workers' comp filing deadline. The Minus 30 Rule means your internal deadline is 30 days before the real one. This buffer absorbs rework, missing documentation, and payer routing corrections.
Calculate Your Internal Filing Deadline
Select a state and enter the date of service to calculate your internal filing deadline.
Search by state name, abbreviation (e.g., "TX"), deadline (e.g., "90 days"), or risk level (e.g., "CRITICAL").
Why the Minus 30 Rule Matters
Carriers issue immediate "missing documentation" denials to force resubmission — which resets the clock. Even when the original submission was complete, the resubmission cycle consumes 30-60 days of your filing window. The Minus 30 Rule builds in the buffer you need to survive the first denial and still file on time.
