Sickle cell disease resources in California
California appropriated $15 million in 2021 for the Networking California for Sickle Cell Care initiative, which built adult SCD clinics at UCSF, UCLA, UCSD, UC Davis and Cedars-Sinai — directly addressing the adolescent-to-adult care gap. Medi-Cal published a written policy covering Casgevy and Lyfgenia in 2024.
Roughly 8,300 people in California are estimated to live with sickle cell disease; the figure comes from the CDC's Sickle Cell Data Collection program in participating states and from NHLBI modeling elsewhere. California began universal newborn screening for sickle cell disease in 1990 — every baby born in the state is now screened at birth, which lets families start twice-daily penicillin prophylaxis by two months old and dramatically reduces childhood SCD mortality. For confirmatory testing and hematology follow-up after a positive screen, ask your pediatrician for a referral to the closest comprehensive sickle cell center listed on this page.
California Medicaid covers hydroxyurea — the cornerstone disease-modifying therapy for SCD. California Medicaid published written coverage policy for Casgevy (exa-cel) and Lyfgenia (lovo-cel) in 2024. As of 2026, only roughly 45 comprehensive centers nationally are authorized to administer Casgevy (exa-cel), and fewer still are authorized for Lyfgenia (lovo-cel). Coverage status alone doesn't guarantee access — patients must be at least 12 years old with recurrent vaso-occlusive crises, enrolled at an authorized center, and cleared through the center's multi-step stem-cell-collection and conditioning protocol.
Community support in California runs through Cayenne Wellness Center (SCDAA of California). SCDAA chapters coordinate annual Sickle Cell Awareness events, patient education, and advocacy — most keep a current list of pediatric and adult comprehensive clinics in the state and can help patients navigate insurance pre-authorization for disease-modifying therapies.

For Black families
Roughly 1 in every 365 Black infants born in the United States inherits sickle cell disease, and roughly 1 in 13 carries the sickle cell trait — the highest carrier frequency of any population group in the country. Because newborn screening is universal, nearly every Black family in California whose baby has SCD receives the diagnosis before they leave the hospital — which is exactly why timely follow-up with a comprehensive center matters more than the diagnosis itself.
The hardest periods in the SCD lifespan are the transition from pediatric to adult care (roughly ages 18-25, when preventable mortality peaks) and emergency-department visits for vaso-occlusive crises, where published research has consistently documented longer time-to-analgesia and higher suspicion of drug-seeking behavior for Black SCD patients than for white patients with comparable pain. Transition programs, pain plans, and hematologist letters addressed to ED staff reduce both. Every comprehensive center listed on this page supplies those materials on request.
