What This Code Means

CO-29 is applied when a claim exceeds the allowed time frame for submission. Filing limits are set by payer policy and contract terms. Once expired, claims are typically not eligible for payment. This is an administrative determination, not a coverage decision. Exceptions are uncommon and payer-specific.
