Although an injured worker can receive services from more than one provider (i.e., treating providers), a physician of record is responsible for assuring that timely, appropriate care is being requested and delivered. A claim may only have one physician of record. A physician of record must be a medical doctor, a doctor of osteopathic medicine, a doctor of mechanotherapy, a doctor of chiropractic, a doctor of podiatry, a doctor of dental surgery or licensed psychologist. A physician of record is commonly referred to as a “POR.”
