Texas HMO Withdrawal Guidelines are a set of rules that allow HMO members to withdraw from the plan without penalty. These guidelines can vary depending on the type of plan and whether the member is currently enrolled in an HMO. Generally, Texas HMO Withdrawal Guidelines require members to submit a written request to the HMO in order to be officially withdrawn from the plan. The request must include the member's name, address, and date of withdrawal. There are two types of Texas HMO Withdrawal Guidelines: voluntary and involuntary. Voluntary withdrawal occurs when a member decides to voluntarily leave the plan. The HMO must accept the member's request for withdrawal within 30 days of the date of the written request. Involuntary withdrawal occurs when an HMO terminates a member's coverage due to non-payment of premiums or other factors. The HMO must provide notice to the member at least 60 days prior to the termination of coverage.
