What billers should know
Kaiser operates regionally (CA, CO, GA, HI, MD/VA/DC, NW, WA) and limits vary by regional contract. Out-of-plan emergency claims often have different windows.
Missed the Kaiser Permanente deadline?
- 1
Pull your proof of timely submission — clearinghouse acceptance reports (277CA), payer portal submission logs, or EDI acknowledgments. If the claim was submitted in time and lost or rejected downstream, most payers must reopen it.
- 2
The denial arrives as CO-29 — appeal with documentation, citing the original submission date and any payer-side errors (wrong member ID on file, retroactive eligibility, COB delays).
- 3
If the miss is genuinely yours, write it off correctly: timely filing denials are a contractual adjustment — billing the patient for them violates most network agreements.
- 4
Fix the root cause: charges should leave the door within 48–72 hours of the encounter, with a worklist for anything unbilled after 7 days.
