The Department of Health Care Services (DHCS) gives health plan guidelines on how far and how long it should take for members to access health care services. Time and distance standards are:
| Provider Type | Time and Distance Standard |
| Primary Care (Adult and Pediatric) | 10 miles or 30 minutes from a member’s residence |
| Specialty Care (Adult and Pediatric) *including OB/GYN | 15 miles or 30 minutes from a member’s residence |
| Hospital | 15 miles or 30 minutes from a member’s residence |
Some ZIP codes do not have providers within the standard Time and Distance guidelines. CHOC Health Alliance has received approval from CalOptima Health to use alternative standards in these areas.

If you live in one of the listed ZIP codes and need care from the specialty provider listed, call Member Services at (800) 424-2462. We can help you find a nearby provider, arrange free transportation if a local provider is unavailable, and provider free language assistance. We may also connect you with a closer provider outside our network when needed.
