Summary
HealthNet California has updated their preferred pharmacy network for Medicare Advantage Part D and Prescription Drug Plans. This affects which pharmacies patients can use for prescription medications with potentially different copays or coverage levels.
Action Required
Immediately: Front desk staff should inform patients about the updated preferred pharmacy network when scheduling appointments or discussing medications. Providers should advise patients to verify their pharmacy is still in-network or help them find a new preferred pharmacy to avoid higher out-of-pocket costs.
