Worker’s compensation and OSHA operate entirely independent from each other. The determination of what makes an injury compensable may be defined differently from state to state, but OSHA is very specific in Part 1904 in what is and is not recordable.
Worker’s compensation can deny claims for a number of reasons such as not going to doctor’s appointments or failing a post accident screen. OSHA’s definitions of recordables have no clauses for extenuating circumstances or compliance in the investigation. A work-related amputation is a recordable no matter which way the wind blows and is not up for discussion.
