C. For the purposes of this section:

(1) “ H ” or “ heavy ” means the ability to lift over fifty pounds occasionally or up to fifty pounds frequently;

(2) “ M ” or “ medium ” means the ability to lift up to fifty pounds occasionally or up to twenty-five pounds frequently;

(3) “ L ” or “ light ” means the ability to lift up to twenty pounds occasionally or up to ten pounds frequently. Even though the weight lifted may be only a negligible amount, a job is in this category when it requires walking or standing to a significant degree or when it involves sitting most of the time with a degree of pushing and pulling of arm or leg controls or both; and

(4) “ S ” or “ sedentary ” means the ability to lift up to ten pounds occasionally or up to five pounds frequently. Although a sedentary job is defined as one that involves sitting, a certain amount of walking and standing is often necessary in carrying out job duties. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

D. The determination of a worker's residual physical capacity shall be made by a health care provider defined in Subsection C , E or G of Section 52-4-1 NMSA 1978 . If the worker or employer disagrees on who shall make this determination, the dispute shall be resolved in accordance with the provisions set forth in Section 52-1-51 NMSA 1978 .
