b. "Maximum medical improvement" means the injured employee's recovery has progressed to the point where substantial further improvement is unlikely, based on reasonable medical probability and clinical findings indicate the medical condition is stable.

c. "Medical dispute" means an employee has reached maximum medical improvement in connection with a work injury and has been evaluated for permanent impairment, and there is a disagreement between health care providers arising from the physical evaluation that affects the amount of the award. The dispute to be reviewed must clearly summarize the underlying medical condition. It does not include disputes regarding proper interpretation or application of the American medical association guides to the evaluation of permanent impairment, sixth edition. It does not include disputes arising from an impairment percentage rating or an impairment opinion given by a health care provider when the health care provider is not trained in the American medical association guides to the evaluation of permanent impairment, sixth edition, and when the health care provider's impairment percentage rating or impairment opinion do not meet the requirements of subsection 5 of North Dakota Century Code section 65-05-12.2.

2. Permanent impairment evaluations must be performed in accordance with the American medical association guides to the evaluation of permanent impairment, sixth edition, and modified by this section. All permanent impairment reports must include the opinion of the health care provider on the cause of the impairment and must contain an apportionment if the impairment is caused by both work-related and non-work-related injuries or conditions.

3. The organization shall schedule an evaluation with a health care provider who has the training and experience necessary to conduct an evaluation of permanent impairment and apply the American medical association guides to the evaluation of permanent impairment, sixth edition. The organization may not use nor consider a permanent impairment evaluation conducted by the employee's treating health care provider or any health care provider who has treated the injured employee for the work-related injury. In the event of a medical dispute, the organization will identify qualified specialists and submit all objective medical documentation regarding the dispute to specialists who have the knowledge, training, and experience in the application of the American medical association guides to the evaluation of permanent impairment, sixth edition.

4. Upon receiving a permanent impairment rating report from the health care provider, the organization shall audit the report and shall issue a decision awarding or denying permanent impairment benefits.

a. Pain impairment ratings. A permanent impairment award may not be made upon a rating solely under chapter 3 of the sixth edition.

b. Mental and behavioral disorders are not independently compensable and are encompassed within the rating for physical impairment.

c. In chapters that include assessment of the functional history as one of the nonkey factors to adjust the final impairment rating within a class by using a self-report tool, the examining health care provider is to score the self-report tool and assess results for consistency and credibility before adjusting the impairment rating higher or lower than the default value. The evaluating health care provider must provide rationale for deciding that functional test results are clinically consistent and credible.

d. A functional history grade modifier may be applied only to the single, highest diagnosis-based impairment.

e. All permanent impairment reports must include an apportionment if the impairment is caused by both work and non-work injuries or conditions.

5. Pollicization procedures will be rated as an impairment under subsection 11 of North Dakota Century Code section 65-05-12.2, relating to scheduled injury, and may not be rated as a whole body impairment, unless otherwise specified under subsection 11 of North Dakota Century Code section 65-05-12.2.
