Phillip M. Jensen, D.D.S. — Fentanyl Theft from Surgical Patients and Surgeries Without Anesthesia (2024)
Outcome: Dentist Phillip M. Jensen was sentenced to 15 years in federal prison and ordered to pay a $200,000 fine after pleading guilty to stealing fentanyl from at least 99 surgical patients, injecting them with saline-diluted vials, and performing oral and maxillofacial surgeries without proper pain management.
Phillip M. Jensen, 64, practiced as an oral and maxillofacial surgeon in Rochester, Illinois. His state dental license was suspended in 2022. Beginning as early as December 2019 and continuing until his suspension, Jensen engaged in a systematic scheme of controlled substance diversion from his own surgical patients.
Jensen's method was consistent and deliberate: he removed safety caps from single-use fentanyl vials, withdrew at least half the fentanyl from each vial for his personal use, refilled the vials with saline to restore their apparent volume, and glued the caps back in place to conceal the tampering. He then administered the diluted vials to patients undergoing oral surgery procedures — including tooth extractions and jaw bone reshaping — who received significantly less anesthesia than their records indicated. Jensen stole more than 40 grams of fentanyl through this scheme. He made false entries in surgical records claiming full-strength fentanyl had been administered and billed both public and private insurance programs for services supported by fraudulent documentation.
The scheme came to light when clinical staff noticed patients were moving, moaning, and showing signs of significant pain and distress during surgical procedures. In one documented instance, when Jensen realized a patient had regained consciousness during surgery, he struck the patient in the head with a surgical instrument and completed a procedure involving multiple tooth extractions and jaw bone reshaping while the patient was conscious and without effective pain management.
Jensen pleaded guilty in August 2024 to two counts of drug diversion, two counts of acquiring a controlled substance by fraud, one count of tampering with consumer products resulting in serious bodily injury, and two counts of making false statements relating to health care matters. On December 18, 2024, he was sentenced to 15 years in federal prison and ordered to pay a $200,000 fine. More than 99 identified victims testified at his sentencing. The case was investigated by the DEA Diversion Unit, the Sangamon County Sheriff's Office, the FDA Office of Criminal Investigations, and the Illinois Department of Financial and Professional Regulation.

How Crucible Prevents This
Crucible's controlled substance reconciliation controls enforce vial-level accounting of Schedule II narcotics, making tampering with fentanyl vials — including removal and saline substitution — detectable through pre/post-procedure inventory counts. Mandatory post-operative documentation workflows requiring patient vital sign and sedation records would have surfaced the pattern of inadequate anesthesia across 99+ cases far earlier. Secure chain-of-custody logging for controlled substance vials from receipt to administration prevents substitution events. Patient outcome documentation requirements would have flagged the abnormal intraoperative distress reports that ultimately alerted staff.
