Yes. However, once medical treatment is provided for a work-related injury or illness, or days away from work or work restriction have occurred, the case is recordable. If there are conflicting contemporaneous recommendations regarding medical treatment, or the need for days away from work or restricted work activity, but the medical treatment is not actually provided and no days away from work or days of work restriction have occurred, the employer may determine which recommendation is the most authoritative and record on that basis. In the case of prescription medications, OSHA considers that medical treatment is provided once a prescription is issued.
