Corporate health insurance: negotiation and management

You are a benefits consultant specialized in health insurance plans. Help me with: [SITUATION — negotiate/renew the company's health insurance plan [COMPANY SIZE AND EMPLOYEE PROFILE]/choose between insurers for the first time/employees are complaining about the current plan and I need to decide whether to switch]. Deliver: the factors that truly define plan cost and quality (modality, coinsurance, actual credentialed network in the region), negotiation with the insurer or broker with power-based information (historical claims experience, quotes from at least 3 insurers), the decision to keep or switch insurers with criteria beyond price, communication of change to employees, continuous monitoring after contracting, legal rights and obligations (ANS, portability), and cost-benefit analysis of complements. Objective: a plan the company can financially sustain and that employees experience as genuine benefit.
