Kaiser Permanente Corporate Office, Headquarters, Member Services, and Complaint Information 

🗨  Comments 

Kaiser Permanente is one of the largest not-for-profit health plans and integrated health care organizations in the United States. This page provides updated Kaiser Permanente corporate office and headquarters information, including the Oakland headquarters address, corporate phone number, member support routes, complaint and grievance guidance, privacy reminders, and escalation tips.

Kaiser Permanente Corporate Office and Headquarters Information

Kaiser Permanente is headquartered in Oakland, California. Because Kaiser operates through regional health plans, hospitals, medical offices, and Permanente Medical Groups, member complaints are usually handled through the member’s region, health plan, medical center, pharmacy, or grievance process rather than only through the national headquarters office.

Emergency warning: If you believe you or someone else is experiencing a medical or mental health emergency, call 911 or go to the nearest emergency room. Do not use this page, a public comment, or a corporate office contact form for emergency care.

About Kaiser Permanente

Kaiser Permanente was founded in 1945 and is known for combining health coverage, hospitals, physicians, pharmacies, medical offices, digital tools, and care coordination within an integrated health care model. Kaiser Permanente operates in multiple regions, including California, Colorado, Georgia, Hawaii, the Mid-Atlantic States, Nevada, the Northwest, and Washington.

Kaiser Permanente’s national organization includes Kaiser Foundation Health Plan, Inc., Kaiser Foundation Hospitals and its subsidiaries, and regional Permanente Medical Groups. Because the organization is regional, the best contact route often depends on where the member lives, where the care was provided, and which Kaiser Permanente plan or medical office is involved.

How to Contact Kaiser Permanente About a Complaint

For most complaints, start with Kaiser Permanente Member Services for your region or use the official complaint form and select the region where the issue occurred. Complaints involving care, billing, prescriptions, appointments, claims, medical records, pharmacy service, or access to specialists may require different departments.

  • Care complaints: Include the medical center, department, provider name if known, visit date, and a clear summary of the issue.
  • Billing complaints: Save the bill, explanation of benefits, account number, payment records, claim details, and written communications.
  • Pharmacy complaints: Include the pharmacy location, prescription name, refill date, medication issue, and any pharmacist or case notes.
  • Appointment or access complaints: Document appointment dates, wait times, cancellations, referral delays, and screenshots from kp.org or the app.
  • Grievances and appeals: Use Kaiser’s official grievance or appeal process and keep the case number for follow-up.
  • Medical records: Use Kaiser’s official medical information request route rather than posting personal health information publicly.

Kaiser Permanente Grievances, Appeals, and Escalation Tips

If your issue is not resolved through normal Member Services, ask whether it should be handled as a grievance, appeal, claim review, quality-of-care complaint, or billing dispute. Kaiser Permanente provides region-based complaint and grievance routes through its official Support Center.

When escalating a Kaiser Permanente complaint, keep copies of:

  • Case numbers, grievance numbers, or appeal numbers
  • Dates and times of phone calls, chats, emails, and appointments
  • Provider names, facility names, pharmacy locations, or department names
  • Bills, receipts, payment confirmations, and claim notices
  • Prescription records, refill requests, and pharmacy communications
  • Referral requests, appointment confirmations, and cancellation notices

Reader comments on this page have included concerns about parking and access at a Kaiser facility, pharmacy service, prescription handling, testing access, billing disputes, and difficulty reaching a higher-level contact. If you share a comment below, keep it factual and avoid posting private medical information.

Privacy and Medical Information Warning

Do not post your medical record number, Social Security number, full date of birth, diagnosis, prescription details, test results, insurance ID, address, phone number, or other private health information in a public comment.

CorporateOfficeHeadquarters.com cannot access Kaiser Permanente accounts, medical records, bills, claims, prescriptions, grievances, appointments, test results, or provider notes. For medical advice, prescription questions, lab results, or urgent symptoms, contact Kaiser Permanente directly or speak with your medical care team.

Fraud and Scam Warning for Kaiser Permanente Members

Be careful with fake Kaiser Permanente calls, emails, text messages, bills, refund notices, pharmacy alerts, appointment links, job offers, or insurance-payment messages. Scammers may impersonate health care companies to collect personal, medical, login, insurance, or payment information.

Use only official Kaiser Permanente websites and apps when signing in, paying a bill, reviewing records, or sending private health information. If you receive a suspicious message, do not click unexpected links or share verification codes. Contact Kaiser Permanente directly through the official website, the number on your member ID card, or the Support Center.

Kaiser Permanente Colorado Springs CO Disappointing

February 13, 2025

Kaiser Permanente, To The CEO of Kaiser Permanente, I have been humiliated and mistreated by the pharmacy staff at Kaiser Premiere, Colorado Springs, for the last time. The manager, Ryan, has been unable to take care of the needs of more than a dozen Kaiser customers that I know of over the last five years. I have filed numerous complaints, including receiving the wrong medication, receiving the wrong quantity, being provided warm medication that is supposed to be kept cold, and not having medication ready for pick up when promised. Ryan also allows staff like Creed to be rude on a regular basis with apologies or promises it will no longer happen. In fact, Creed made a completely inappropriate comment to me about the number of meds I take. He said, “No wonder you are sick with all this medicine you’re taking”. I filed a complaint with the office and Kaiser customer service, so Creed and Ryan have continued to be rude and disrespectful to me and others. Most recently, a few weeks ago on a Friday night (January 24th), Ryan, the pharmacy manager, had a line going all the way to the lobby, and only one person waiting on customers–Creed. Instead of jumping in to help, Ryan closed all the merchandise doors and helped a customer who skipped to the front of the line. I had waited in line for 20+ minutes when another clerk started helping customers. Unfortunately, I was called to Creed’s window, and once again, he treated me horribly from the start. He started by stating that my medication wasn’t ready. I told him I called the refills in the night before, but the new meds were sent in by my doctor that day. He told me that they had until Monday to fill the prescriptions and tried to call the next person. I told him to wait a minute and that I needed them before I went out of town. He repeated that they wouldn’t fill them that night and the next customer again. Meanwhile, the extremely sweet lady with blond hair had waited on and was getting several customer’s meds filled while they waited. Creed said (which I wrote down), “If you want your meds, you can go north or go south, but you’re not getting them filled here!” I told him I couldn’t since I just had bloodwork done down the hall and I felt dizzy. He responded by saying, “I don’t believe that happened”. Then, he added, “You don’t have a choice about which pharmacy you go to; we’re not filling this prescription tonight or ever at this location”, and he said again, “You can go north or go south, but you’re not staying here!” Ryan yelled my name so the entire waiting area could hear, and he said, “I’m not doing this with you. I’m calling security.” I responded by saying, “Good, I’ll go with you!” I told the security guard what happened, and he told me, “Sorry for the trouble, Mam.” At that point, I thanked the security guard and left. I drove 25 minutes to the Briargate pharmacy and asked if she could fill my meds, and she did so on the spot! Today, Ryan told the customer service rep that security had to escort me out that night! What a liar!

I have filed two complaints and tried repeatedly to get ahold of someone at the corporate offices, but to no avail. So, I am posting this review instead! My wonderful doctors are at Kaiser Premier, but that pharmacy refuses to fill my prescriptions. That is just wrong!!!

Kaiser Permanente Frustrating Testing Issue

February 12, 2025

Kaiser Permanente, Difficulty Accessing Needed Medical Test. I am extremely frustrated with Kaiser Permanente’s policy requiring a companion for certain medical tests. I need a test to check for cancer, but since I don’t have anyone to accompany me, I’m unable to get it done. I have reached out to social workers, volunteer organizations, and medical services, but none have been able to help. Despite calling multiple numbers in Seattle, I haven’t made any progress. As members, we should have direct access to corporate headquarters to address the policies that impact our healthcare.

Kaiser Permanente Question

January 13, 2024

I have been trying to work for Kaiser Permanente since 1999. I do admit I stopped when my Mom took ill. Now I was offered a job, but it was in San Francisco. I couldn’t take it at the time, due to the fact my Father had taken ill. I know the first time the person in charge of hiring was Ms. Lawson. She was married to my Friend’s husband and she let it be known she wasn’t going to hire me. the rest, I have been trying since 2015.

Kaiser - No Charge For Light Therapy Then Suddenly They Made A Mistake Now I Owe $450.00

January 8, 2024

I was told no charge for light therapy then suddenly they made a mistake and wanted to charge but waited to let me know this after I owed for 9 visits. So, I then owed $450.00 I went for almost two years being told at the window and office no charge then suddenly they did this. I understand they want to start charging me but tell me, so I have the decision to stop going. If I went 3 times a week, I would have to pay them $7020.00 a year. It would be cheaper to take a pill or do light therapy at home. They say I can use one of their light machines at home for free I don’t know If they may change their minds and charge me. I don’t know If I can trust what they say to me. They say in my claim they made a mistake but making me pay the $450.00 is like them saying I owe for two years which would be $14000.00. all I ask is to not charge me up until you let me know you made the mistake. at that time, I stop going to therapy…….I’m retired on a fixed income don’t charge me for your mistake. Is anyone listening? I didn’t make the mistake and they admit they did in my dispute claim in Gwinnett Georgia.
