The Advocate Physician Partners appeal form is a one-page document that providers and members use to ask APP to reconsider a denied or underpaid claim. You complete it with the patient’s and provider’s identifying information, the claim number from the Explanation of Benefits (EOB), and a short written explanation of why the denial was wrong, then submit it with supporting documentation to the APP appeals department in Mount Prospect, Illinois.
What to Gather Before You Fill Anything Out
The EOB or denial notice is the anchor document. It carries the claim number, the date of service, the amount billed, the amount allowed, and a reason code explaining the denial. That reason code decides what evidence you need to attach.
Pull the member’s full legal name, date of birth, and member ID exactly as they appear on the insurance card. On the provider side, have the treating physician’s National Provider Identifier (NPI) and tax identification number ready. APP uses these to match the appeal to the correct office and route any resulting payment.
Then match your supporting documents to the reason for denial. If the claim was denied for medical necessity, gather office notes, lab results, imaging reports, or citations to peer-reviewed literature showing the service meets accepted standards of care. If the problem was a billing error, you may only need a corrected procedure code or updated eligibility dates.
Filling Out the Form
The form is available through the Advocate Health website and the provider portal. It has three working sections: member information, provider information, and a narrative.
In the member section, enter the patient’s full legal name, date of birth, and member ID exactly as printed on the card. A small discrepancy can get the appeal returned without review. Add the claim or reference number from the EOB so the appeals team can pull the original determination quickly.
In the provider section, enter the treating physician’s name, NPI, and tax ID number. An incorrect NPI can misdirect payment on a successful appeal, so verify it rather than guessing.
The narrative is where appeals are won or lost. State the specific reason the claim was denied, then explain why that reason is wrong. For a medical-necessity denial, summarize the clinical evidence showing the treatment was appropriate for this patient’s condition. For an administrative denial, point to the specific error and give the corrected information. Keep it factual.
Where to Send the Completed Form
Attach a copy of the original EOB or denial notice to every submission, whichever method you use. Keep proof of delivery; a dispute over whether the form arrived on time is a fight you do not want.
- By mail: send the form and attachments to the APP appeals department at PO Box 0357, Mount Prospect, IL 60056. Certified mail with a return receipt gives you signed confirmation and handles large record packages that may not transmit cleanly by fax.
- By fax: APP accepts appeals by fax. The fax number is printed on the denial notice or EOB. Keep the confirmation page. Fax is usually the fastest option.
- Through the provider portal: registered users can upload a PDF of the form and attachments in the claims and appeals section. The portal issues a digital receipt or tracking number immediately.
How Long You Have to File
Federal regulations require group health plans to give claimants at least 180 days from receipt of a denial notice to file an internal appeal.1eCFR. 29 CFR 2560.503-1 – Claims Procedure Your plan documents may allow more time, but they cannot allow less. Check the denial letter for the exact deadline; the clock starts when you receive the notice, not when the plan mails it.
Even with 180 days on the calendar, file as soon as the paperwork is ready. Records get harder to pull as time passes, and additional coding issues sometimes surface mid-review.
What Happens After You Submit
Once APP receives the appeal, the deadline for its decision depends on the type of claim.
- Post-service claims, where the service has already been performed: a written decision within 60 days of receiving the appeal.1eCFR. 29 CFR 2560.503-1 – Claims Procedure
- Pre-service claims, such as prior authorization disputes: a decision within 30 days.1eCFR. 29 CFR 2560.503-1 – Claims Procedure
- Urgent care claims, where delay could seriously jeopardize the patient’s life or ability to regain maximum function: a response within 72 hours.1eCFR. 29 CFR 2560.503-1 – Claims Procedure
The written result goes to both the member and the provider. If the plan overturns its decision, the claim is reprocessed for payment. If the denial is upheld, the letter must explain why and inform you of your right to further review, including external appeal. Plans must also continue coverage for an ongoing course of treatment while the appeal is pending, so a patient should not lose access to care mid-treatment because the appeal has not yet been decided.2U.S. Department of Health and Human Services. Internal Claims and Appeals and the External Review Process
If the Internal Appeal Is Denied
Under the Affordable Care Act, once the plan’s internal appeals are exhausted, you can request an external review by an independent organization with no connection to the plan.3Centers for Medicare & Medicaid Services. HHS-Administered Federal External Review Process for Health Insurance Coverage External review is available for denials involving medical judgment, including medical necessity, appropriateness, and experimental or investigational treatment determinations.
You have four months from the date you receive the final internal adverse benefit determination to file a written request for external review.4HealthCare.gov. External Review Standard external reviews must produce a written decision within 45 days.3Centers for Medicare & Medicaid Services. HHS-Administered Federal External Review Process for Health Insurance Coverage Expedited review for urgent situations requires a decision within 72 hours. The reviewer’s decision is final and binding on both sides; if the denial is overturned, the plan must cover the service.
Letting Someone Else File for the Patient
If a patient wants a physician, family member, or advocate to handle the appeal, the patient can authorize that person using CMS Form 1696, Appointment of Representative. Both the patient and the representative sign, and the form is valid for one year from the date both signatures are in place.5Centers for Medicare & Medicaid Services. Appointment of Representative The representative then becomes the main point of contact and can submit evidence, receive communications, and access medical information related to the appeal.
Submit the completed CMS-1696 with the appeal itself, to the same address or fax number. Without it on file, the appeals team cannot share claim details or decision letters with anyone other than the member.
