Does this replace our group health insurer?

“No. Anvera Health is a clinical care layer that sits alongside your existing group health policy and benefits-administration stack (Plum, Onsurity, Loop, Pazcare). The insurer continues to cover hospitalisation; Anvera Health delivers the everyday-care relationship that group plans skip — OPD, mental health, women's health, parents care, NCD management, hard-case Consilium access.”
