How to File a Complaint Against Allegheny Health Network

Before filing a complaint, gather the patient’s name, date of birth where appropriate, facility or office name, dates of service, provider names, billing statements, photographs where relevant, and records of earlier conversations. Do not include unnecessary sensitive health information when communicating through unsecured channels.

Step 1: Speak With the Immediate Care Team

If the patient is still receiving care, raise the concern with the nurse, physician, department manager, or other responsible staff member as soon as possible. Many communication, comfort, scheduling, and service concerns can be addressed while the patient is still at the facility, making early discussion one of the fastest routes to resolution.

Step 2: Contact the Facility Manager or Patient Relations Team

If the problem is not resolved by frontline staff, ask for the hospital or facility’s patient-relations, patient-experience, or administrative representative. Provide a clear description of what happened, the dates involved, previous staff contacts, and the outcome you want. Keep the name of each person contacted and any case or reference number provided.

Step 3: Submit AHN’s Official Feedback Form

AHN’s Contact Us page invites patients to submit praise as well as concerns about patient safety and quality of care. Use the official feedback process and provide enough information for AHN to identify the facility and service involved without sending unnecessary sensitive material through unsecured channels.

Step 4: Contact Billing Support for Financial Complaints

For bills, charges, financial assistance, or payment disputes, call 844-801-8400 and select option 1. Explain which charge is disputed, identify the date of service, provide any insurance explanation of benefits, and request that the account be reviewed before sending unrelated clinical complaints through the billing department.

Step 5: Resolve Medical Records or MyChart Issues Separately

For record-access concerns, use AHN’s Medical Records process. MyChart technical issues should be directed to 833-246-2478, option 4, or MyChart@ahn.org. Keeping technical-account complaints separate from clinical grievances makes it easier for each department to resolve the correct issue.

Step 6: Request Further Administrative Review

If the complaint remains unresolved after Patient Relations or the relevant department responds, request additional administrative review. Provide previous case numbers, names of employees already contacted, a concise timeline, and any written response you believe did not address the concern.

Step 7: Send Formal Written Correspondence to AHN Headquarters

A serious unresolved complaint can be sent to Allegheny Health Network Headquarters, 120 Fifth Avenue, Suite 2900, Pittsburgh, PA 15222. Include contact information, the hospital or facility, dates, previous complaint numbers, and the requested resolution. Send copies rather than original medical or financial documents and keep proof of delivery.

Step 8: Contact the Appropriate Healthcare Regulator

If the complaint concerns professional conduct, hospital quality, licensing, or patient safety and remains unresolved, the appropriate external route can include the Pennsylvania Department of Health, a professional licensing board, or an accreditation body depending on the issue. Use the regulator that actually oversees the type of care or professional involved.

Step 9: Use External Privacy, Insurance, or Civil Rights Channels When Appropriate

Privacy complaints may involve the U.S. Department of Health and Human Services Office for Civil Rights, while insurance disputes may need to go through the applicable health plan or state insurance regulator. Civil-rights concerns should be routed through the appropriate nondiscrimination process. Keep AHN correspondence and all supporting documents before filing externally.
