Maryland Insurance Timely Filing


Maryland Insurance Code §15-1005 requires insurers to pay clean claims within 30 calendar days of receipt or issue a written denial. This statute establishes clear deadlines and imposes tiered interest penalties for late payments.

Maryland's 30-Day Payment Requirement

Insurers operating in Maryland must process clean claims on a standardized timeline. A clean claim is one that contains all necessary information for adjudication. Once submitted, the 30-day clock begins immediately. Electronic submissions are treated identically to paper claims.

Incomplete claims trigger a separate process: the insurer must identify deficiencies within 30 days of receipt. The 30-day payment clock then restarts upon submission of the corrected claim, not from the original submission date.

Tiered Interest Penalty Structure

Maryland's interest structure escalates based on payment delay:

Days Overdue Interest Rate
31-60 days 1.5% per month
61-120 days 2% per month
121+ days 2.5% per month

Interest accrues separately and must be itemized from the claim payment. Providers can demand interest as a separate line item on remittance.

Enforcement and Penalties

The Maryland Insurance Administration (MIA) enforces timely filing requirements. Insurers that violate the statute face regulatory sanctions. Maryland Insurance Code §4-113 permits fines up to $500 per violation for arbitrary or capricious denial. Pattern violations trigger market conduct examinations.

How to Claim Interest on Late Payments

Document the original submission date, calculate accrued interest at the applicable tier, and submit a written demand to the insurer. If the insurer does not respond within 15 days, escalate to the MIA with copies of all correspondence and proof of submission.
