On Oct. 25, a nurse at the ASC found a discrepancy in the number of fentanyl vials used by Dr. Christensen that day and reported the information to the Wyoming Professional Assistance Program.
Dr. Christensen later admitted he diverted a vial but did not use it, as well as that he had used fentanyl earlier in the year. He then failed to provide a nail sample for testing, the report said.
The Wyoming Board of Medicine suspended his license Dec. 5.
