Kaiser Permanente Appeal Form for Providers in Northern and Southern California

What is a Provider Dispute Notice? It is Kaiser Foundation Health Plan's term for a contracted or non-contracted provider's written or online challenge to a claim denial, adjustment, contest or overpayment request, identified by Kaiser's original claim number and the member's medical record number (MRN).

Undeny's Take

Kaiser is the most data-literal payer on this list. It identifies members by medical record number, not subscriber ID, and a notice without the MRN, the Kaiser claim number or your billing TIN is rejected as incomplete rather than worked. So the winning habit is boring: copy the MRN and claim number straight from the EOP into every submission, file through Online Affiliate so you get the two-day acknowledgment, and save that acknowledgment as your proof of receipt. The other Kaiser habit to break is "just rebill it." Kaiser's claim FAQ for Southern California behavioral health providers warns that a second claim for the same date and code is viewed as a duplicate; fix errors with a replacement claim that points to the original claim number, and keep disputes for genuine disagreements.

PDRR, MRN and Online Affiliate: Kaiser's Vocabulary

Kaiser's California documents use a few terms you will see on every EOP and letter:

• Provider Dispute Notice: any payment dispute, whether filed online or on paper.
• PDRR: the Kaiser Provider Dispute Resolution Request form, the Kaiser appeal form most billers are looking for, which Kaiser recommends for disputes on emergency or referred services claims. A copy is printed inside Kaiser's Claims Settlement Practices notice effective November 1, 2025.
• MRN: the Kaiser medical record number that identifies each member on claims and disputes.
• Online Affiliate: Kaiser's secure provider portal for claim status, online disputes and supporting documents.
• National Claims Administration: the Kaiser office that receives and resolves provider disputes.

The Northern California manual notes that this process "applies to disputes subject to the Knox-Keene Act," and Kaiser's claims notice says it "will follow the Knox-Keene Act, Medicare, or Medi-Cal requirements for claim processing, as applicable." For members visiting from another Kaiser region, the manual sends you to the member's home region for dispute information.

Filing Through Online Affiliate or the Regional PO Box

Kaiser's manual encourages contracted providers to try resolving billing and payment issues with Kaiser staff first. If that fails, file a Provider Dispute Notice. "Subject to any longer period specifically permitted under your Agreement or required under applicable law," it must be received within 365 calendar days from Kaiser's action, or from the most recent action if there were several.

1. Pull the Kaiser claim number, member name and MRN, dates of service and billed TIN from the EOP or remittance.
2. Count 365 calendar days from the date of Kaiser's action on the claim and calendar the deadline.
3. Write a clear explanation of why the payment, denial, adjustment or overpayment request is wrong, and gather the supporting documents.
4. File online through KP Online Affiliate for your region, which Kaiser encourages for single disputes.
5. Or mail the PDRR or a complete letter: Northern California to National Claims Administration, Attention: Provider Dispute Services Unit, P.O. Box 8002, Pleasanton, CA 94588; Southern California to Claims Administration Department, P.O. Box 7006, Downey, CA 90242-7006.
6. Expect an acknowledgment within 2 working days for online filings or 15 working days for paper.
7. If Kaiser rejects the notice as incomplete, send the amended notice within 30 business days of the rejection letter, and never later than 365 calendar days after Kaiser's last action.
8. Watch for the resolution letter, due within 45 working days of Kaiser receiving the complete dispute.

Data Elements Kaiser Rejects Disputes Without

Kaiser's November 2025 claims notice lists the minimum: provider name, provider tax ID number, contact information, Kaiser claim number, member medical record number, dates of service and the reason for the dispute. The Northern California manual adds that the explanation must show why the payment amount, request for information, overpayment request, contest, denial or adjustment is incorrect. If you file for a group of members, include every member's name and MRN.

If a billing service, collection agency or attorney files for you, Kaiser requires "confirmation that an executed business associate agreement between you, as the provider of health care services, and such representative is in place." Without it, the dispute is returned to the representative.

90 Days Contracted, 180 Days Non-Contracted

The Kaiser timely filing limit depends on contract status and claim type:

Claim situation (California)	Filing limit	Kaiser source
Contracted provider, original claim	90 calendar days after the date of service or discharge, unless your Agreement or law says otherwise	Claims notice (11/1/25) and 2026 Northern California manual
Non-contracted provider, commercial member	180 calendar days	Kaiser Change Healthcare FAQ (April 2024)
Corrected claim after a missing-information denial	Same limit as the original claim, counted from the original Remittance Advice date	2026 Northern California manual
Kaiser secondary to another plan	COB information within 90 calendar days from the primary carrier's EOB	2026 Northern California manual

A late claim is not automatically dead. Kaiser's claims notice says claims "denied for being filed beyond the deadline may be accepted and adjudicated" through the provider dispute process. Kaiser's 2021 claim FAQ for Southern California behavioral health providers says it accepts system-generated reports showing the original submission and acceptance date, and that "handwritten or typed documentation is not acceptable proof of timely filing." Our CO-29 guide covers building that proof.

Replacement Claims Versus Disputes

Use a replacement claim when your claim data was wrong and a dispute when Kaiser's decision was wrong. Kaiser accepts corrections for an incorrect diagnosis, procedure, member, date of service or rate, or when an authorization was obtained, and says "replacement claims should only be submitted after the original claim has been processed." Electronically, enter frequency code 7 in CLM05-3 and the original claim number in REF F8; claims without a valid original claim number are rejected. On paper, use box 22 for the resubmission code and original reference number. Sending a fresh claim instead invites a duplicate denial such as CO-18. Kaiser also does not accept claims that are handwritten, faxed or photocopied.

Batches of Similar Claims

If you have more than 20 substantially similar disputes, the Northern California manual asks you to contact Kaiser first so it can look for a root cause. Online Affiliate cannot take batches, so batches go by mail, with each claim individually numbered and carrying the provider name, TIN, contact information, Kaiser claim number, MRN, dates of service and the basis for the dispute. A batch missing any element is rejected as incomplete.

Senior Advantage and Medicare Members

For Kaiser Medicare members, Medicare Advantage rules also apply. Under CMS guidance, a non-contracted provider whose claim is denied has 65 calendar days from the remittance notification to request reconsideration and must include a Waiver of Liability holding the member harmless. CMS requires the plan's remittance or denial notice to explain these appeal rights, so follow the instructions printed on Kaiser's notice for that claim. Contracted providers follow their Agreement and Kaiser's dispute process.

Common Errors on Kaiser Submissions

• Using the subscriber's ID or name instead of the patient's MRN.
• Disputing a claim that should have been a replacement claim, or rebilling a claim that should have been disputed.
• Assuming the 365-day dispute window also extends the 90-day filing limit for original claims.
• Letting a billing company file without a business associate agreement confirmation.
• Uploading a batch through Online Affiliate, which does not support batches.
• Billing a member during a non-contracted dispute, which Kaiser's form strongly urges providers not to do.
• Treating a referral or authorization denial like CO-197 as a coding problem instead of attaching the referral.

Frequently Asked Questions

Where is the Kaiser Permanente provider appeal form?

The Provider Dispute Resolution Request (PDRR) is printed inside Kaiser's Claims Settlement Practices and Provider Dispute Resolution Mechanisms notice, and Northern California providers can also request it from the Provider Dispute Resolution Unit. You may instead file online through Online Affiliate or send a letter with all required information.

What is the Kaiser Permanente timely filing limit?

In California, contracted providers must submit claims within 90 calendar days after the date of service or discharge unless their Agreement says otherwise. Kaiser's 2024 Change Healthcare FAQ describes the standard limit for non-contracted commercial claims as 180 calendar days.

How long does Kaiser take to resolve a provider dispute?

Kaiser acknowledges online disputes within 2 working days and paper disputes within 15 working days. It issues a resolution letter within 45 working days after receiving a complete dispute, so the clock does not start on an incomplete one.

Can a billing company file a Kaiser dispute for my practice?

Yes, a billing service, collection agency or attorney you authorize can file. The representative must confirm that a HIPAA business associate agreement with you is in place, or Kaiser returns the dispute until the confirmation is included.

Should I send a corrected claim or a dispute to Kaiser?

Send a replacement claim with frequency code 7 and the original claim number when your claim data was wrong. File a Provider Dispute Notice when you disagree with how Kaiser paid, denied or adjusted a correct claim. A second original claim for the same service is treated as a duplicate.

Do these deadlines apply to Kaiser Medicare members?

Partly. Kaiser says its dispute process applies to disputes subject to California's Knox-Keene Act and that it follows Medicare requirements where they apply. For a non-contracted Medicare Advantage denial, follow the instructions on Kaiser's notice; CMS guidance allows 65 calendar days and requires a signed Waiver of Liability.

Informational only, not legal, medical, or billing advice. Verify against Kaiser's current California provider manual, claims notice and your Agreement before filing.
