(a) There is a worsening of a compensable injury that results in the inability of the worker to work and requires hospitalization or inpatient or outpatient surgery, or other curative treatment prescribed in lieu of hospitalization that is necessary to enable the injured worker to return to work. In such cases, the payment of temporary disability compensation in accordance with ORS 656.210, 656.212 (2) and 656.262 (4) may be provided from the time the attending physician authorizes temporary disability compensation for the hospitalization, surgery or other curative treatment until the worker’s condition becomes medically stationary;

(b) The worker submits and obtains acceptance of a claim for a compensable new medical condition or an omitted medical condition pursuant to ORS 656.267 and the claim is initiated after the rights under ORS 656.273 have expired. In such cases, the payment of temporary disability compensation in accordance with the provisions of ORS 656.210, 656.212 (2) and 656.262 (4) may be provided from the time the attending physician authorizes temporary disability compensation for the hospitalization, surgery or other curative treatment until the worker’s condition becomes medically stationary, and the payment of permanent disability benefits may be provided after application of the standards for the evaluation and determination of disability as may be adopted by the Director of the Department of Consumer and Business Services pursuant to ORS 656.726; or

(c) The date of injury is earlier than January 1, 1966. In such cases, in addition to the payment of temporary disability compensation, the payment of medical benefits may be provided.

(c) Do not include medical services provided pursuant to ORS 656.245 except as provided under subsection (1)(c) of this section; and

(3) An order or award made by the board during the time within which the claimant has the right to request a hearing on aggravation under ORS 656.273 is not an order or award, as the case may be, made by the board on its own motion.

(4) Pursuant to ORS 656.298, any party may appeal an order or award made by the board on its own motion.

(5) The insurer or self-insured employer may voluntarily reopen any claim to provide benefits allowable under this section or to grant additional medical or hospital care to the claimant. The board shall establish procedures for the resolution of disputes arising out of a voluntary reopening of a claim under this section.

(6) Any claim reopened under this section shall be closed by the insurer or self-insured employer in a manner prescribed by the board, including, when appropriate, an award of permanent disability benefits as determined under subsections (1)(b) and (2)(d) of this section. The board shall also prescribe a process to be followed if the worker objects to the claim closure.

(7) The provisions of this section do not authorize the board, on its own motion, to modify, change or terminate former findings or orders:
