IEHP's main customer service line is 1-888-275-4347, available Monday through Friday, 8 a.m. to 6 p.m. Pacific Time

IEHP (Inland Empire Health Plan) is a health insurance provider that serves Riverside and San Bernardino counties in California. If you need to speak with someone about your coverage, claims, or account, the phone number above is the primary way to reach them. Wait times vary depending on call volume, and you may be asked to provide your member ID number when you call.

IEHP also operates separate phone lines for specific needs — for example, behavioral health services, pharmacy questions, and provider network inquiries. Knowing which number to call can reduce your wait time and get you to the right department faster.

Key Takeaways

  • The main IEHP customer service number is 1-888-275-4347, open Monday through Friday from 8 a.m. to 6 p.m. Pacific Time.
  • IEHP has separate phone lines for behavioral health, pharmacy services, and provider network questions, which you can find on your member ID card or the IEHP website.
  • Having your member ID number ready before you call will speed up the process.
  • If you cannot reach IEHP by phone during business hours, you can submit questions through your online member portal or by mail.

Separate phone lines for specific services

IEHP routes calls to different departments depending on what you need. If you are calling about mental health or substance abuse services, there is a dedicated behavioral health line. Pharmacy questions go to the pharmacy department. Provider network questions — such as whether a doctor is in-network or how to find a specialist — have their own line as well.

These numbers are printed on the back of your IEHP member ID card. If you have lost your card or cannot find the number you need, call the main line above and ask to be transferred. The representative can also tell you which line handles your specific question.

What to have ready before you call

IEHP will ask for your member ID number to pull up your account. This number is on your member ID card and in any welcome materials IEHP sent you. If you do not have your member ID handy, you can still call, but the representative may ask for your date of birth or Social Security number to locate your account instead.

If you are calling about a specific claim or medical bill, have that document in front of you. The representative will need the date of service, the provider's name, and the amount in question. Having these details ready means the call will move faster and you are more likely to get an answer on the first call rather than being told someone will call you back.

Hours and wait times

The main line is open Monday through Friday, 8 a.m. to 6 p.m. Pacific Time. IEHP is closed on weekends and most federal holidays. Call volume is typically highest in the morning and on Mondays, so if you have flexibility, calling mid-afternoon on a Wednesday or Thursday may mean a shorter wait.

If you reach IEHP and the wait is very long, you have the option to stay on the line, request a callback, or hang up and try again later. Some representatives will offer to take your number and have someone call you back within a certain timeframe.

Other ways to reach IEHP

If you cannot call during business hours or prefer not to wait on the phone, IEHP offers other contact methods. You can log into your member portal on the IEHP website to send a find message to customer service. Responses typically come within one to two business days. You can also mail a letter to IEHP's main office, though this is the slowest option and may take two to three weeks for a response.

For urgent matters — such as a medical emergency or a claim that needs when ready attention — calling the main line is still your fastest option, even if the wait is longer than you would like.

What IEHP customer service can and cannot help with

IEHP customer service can answer questions about your coverage, explain what services are covered under your plan, help you find an in-network provider, and look into the status of a claim. They can also help you understand a medical bill or explanation of benefits (EOB) that you received.

IEHP customer service cannot diagnose medical conditions, recommend specific treatments, or override a coverage decision that was made by a medical reviewer. If your claim was denied and you want to challenge that decision, customer service can explain the appeals process and direct you to the right department, but they cannot reverse the denial themselves.

Frequently Asked Questions

Does IEHP have a phone line for after-hours emergencies?

IEHP's main line does not operate after 6 p.m. Pacific Time on weekdays or on weekends. For a medical emergency, call 911 or go to the nearest emergency room. For urgent but non-emergency questions, you can use the member portal to send a message that will be answered the next business day.

What if I am calling from outside California?

The 1-888 number is toll-free and works from anywhere in the United States. If you are calling from outside the U.S., you may incur international long-distance charges. Check with your phone provider before calling.

Can I reach IEHP by email instead of phone?

IEHP does not publish a general email address for customer service. The member portal is the primary way to send written messages. You can also mail a letter to IEHP's main office address, which is listed on your member ID card and on the IEHP website.

What should I do if I cannot understand the automated menu?

When you call, you can say "representative" or "agent" to skip the automated menu and speak to a person. If English is not your first language, you can request an interpreter at any point during the call, and IEHP will provide one at no cost to you.

How long does it usually take to get a callback if I request one?

IEHP typically calls back within one to two business days if you request a callback. The representative will give you a specific timeframe when you ask. If you do not hear back within that window, call the main line again and reference your previous call.
