This list was compiled using our general knowledge of workers’ compensation and the Maryland Worker’s Compensation Commission website at: http://www.wcc.state.md.us/. We often get asked question like “What does MMI mean?” or “What is AWW in workers’ comp” or how does “Nature and Extent relate to my injuries?” This list is designed to help answer those questions. For more information on anything workers’ comp related, please feel free to contact us.
