Health Net Rehab Centers Along Central Valley Rivers, by the Beach and in the Imperial Desert

Health Net’s California map is uneven: its Medi-Cal plan reaches deep into the Central Valley and the Sierra, while its Ambetter individual plans concentrate in Southern California and the Sacramento area. That split decides which Health Net rule applies along the Central Valley rivers, on the Southern California beaches and in the Imperial Valley desert.

San Diego employers can also choose Salud con Health Net or, for large groups, Salud Mexico, which add SIMNSA providers in Tijuana and Mexicali to San Diego rehab programs.

Can I use Health Net for rehab in a different county or state?

Yes, depending on plan. Medi-Cal coverage follows the county responsible for the member.

How much does rehab cost with Health Net?

Health Net Medi-Cal members pay no copays for covered managed care services. On the 2026 Silver 70 Ambetter plans, inpatient substance use treatment carries 30 percent coinsurance; the PPO version charges 50 percent out of network, while the HMO version does not cover out-of-network care.

Health Net has served California for more than 45 years, and its mix of Medi-Cal, Ambetter, Medicare and employer plans means two members with Health Net cards can follow very different routes into rehab. Southern California treatment programs and sliding scale rehab also appear in the listings.
