LIMITATION OF SERVICES AND BENEFITS ON CONTRACT RENEGOTIATION.

(a) In this section, "health benefit contract" means a contract providing group health care coverage for employees that is delivered, issued for delivery, or renewed in this state by:

(1) an insurance company;

(2) a group hospital service corporation operating under Chapter 842; or

(3) a health maintenance organization operating under Chapter 843.

(b) Subject to Subsection (c), if an employer in this state agrees to renegotiate a health benefit contract, a change in the renegotiated contract may not operate solely to terminate eligibility with respect to any member of the group who, before the contract was renegotiated:

(1) was covered under the contract; and

(2) had a sickness or injury for which a service was being provided or a benefit was being paid under the contract.

(c) A renegotiated health benefit contract may include a different durational or dollar limit or a different deductible amount or amount of coinsurance applicable to a sickness or injury for which a service was being provided or benefit was being paid before the contract was renegotiated if that same or a similar limit or amount applies to a service provided or benefit paid for a similar sickness or a related condition or injury covered by the contract.
