Apportionment: Understanding the Drivers of Pre-Existing Conditions

Dr. John Alchemy discusses one of the most difficult parts of workers’ compensation impairment ratings: Apportionment. When a workers’ compensation injury involves a pre-existing condition on the injured body system, the physician must calculate apportionment to determine how much functional loss was due to the workplace injury, and how much of it is owed to the pre-existing condition. Dr. Alchemy will outline how to navigate through this particularly tough topic for the best outcome for impairment rating.
