(g) Except as provided in subdivision (1), an issuer shall continue to make available for purchase any policy form or certificate form issued after the effective date of this article that has been approved by the commissioner of the department of insurance. A policy form or certificate form shall not be considered to be available for purchase unless the issuer has actively offered it for sale in the previous twelve (12) months and as follows:

1. (1) An issuer may discontinue the availability of a policy form or certificate form if the issuer provides to the commissioner of the department of insurance in writing its decision at least thirty (30) days before discontinuing the availability of the form of the policy or certificate. After receipt of the notice by the commissioner of the department of insurance, the issuer shall no longer offer for sale the policy form or certificate form in this state.
2. (2) An issuer that discontinues the availability of a policy form or certificate form under subdivision (1) shall not file for approval a new policy form or certificate form of the same type for the same standard Medicare supplement benefit plan as the discontinued form for a period of five (5) years after the issuer provides notice to the commissioner of the department of insurance of the discontinuance.

2. (2) does not subsequently put into effect a change of rates or rating factors that would cause the percentage differential between the discontinued and subsequent rates as described in the actuarial memorandum to change. The commissioner of the department of insurance may approve a change to the differential that is in the public interest.

(j) Except as provided in subsection (k), the experience of all policy forms or certificate forms of the same type in a standard Medicare supplement benefit plan shall be combined for purposes of the refund or credit calculation prescribed in 760 IAC 3-11.

(k) Forms assumed under an assumption reinsurance agreement shall not be combined with the experience of other forms for purposes of the refund or credit calculation.
