Sec. 9.01. DISABILITY PENSIONS. (a) A member is eligible for a disability pension if the member's employment is terminated by reason of a disability before the member's 65th birthday.

(b) Payment of a disability pension begins following a 12-month waiting period following the member's termination of service based on disability, except that if disability is presumed to be permanent before the completion of the 12-month period, disability payments begin following the certification of the disability.

(c) Payment of a disability pension may not begin until the disability is certified to be continuous for a period of 90 days.

(d) Payment of a disability pension ends on the member's death or the end of the member's disability. If the disability ends on or after the member's 65th birthday, the member's disability pension shall be continued in the same manner as if the disability had continued.
