What does timely filing mean and why is it critical?

• A. The deadline by which a payer requires claims be submitted; late submissions are typically denied unless a valid exception applies.
• B. The date of service is always the claim submission date.
• C. Filing early guarantees approval.
• D. It only applies to Medicare.

Answer: (A)

Timely filing is the deadline set by a payer for submitting a claim after the date of service. This matters because most payers deny claims that arrive outside their allowed submission window, unless a valid exception is approved. Meeting the timely filing window protects reimbursement and cash flow and guides how you track submissions and manage denials. Remember that the date of service isn’t necessarily the submission date, and meeting the window doesn’t guarantee payment—other factors like coverage, medical necessity, and payer-specific rules still apply. Timely filing windows vary by payer and claim type, and some payers may offer extensions or exceptions in certain circumstances, which you must document and pursue.
