Anchorage Doctor Sentenced for Health Care, Tax Fraud
In a shocking turn of events, Dr. Claribel Tan, a 61-year-old Anchorage doctor, was sentenced to 6.5 years in prison for her role in a $12.5 million health care fraud scheme and evading over $4 million in taxes on the profits of her 15-year scheme.
Dr. Tan, along with her husband, Daniel Tan, 70, operated a rheumatology medical clinic in Anchorage since 2005. The Tans deceived their patients about the kinds and doses of medications Dr. Tan administered through injections in the office and fraudulently billed health insurance plans for reimbursement of medications that they did not purchase or administer to patients.
The Tans’ scheme involved underdosing patients, injecting them with free samples or a different medication than prescribed, injecting them with expired medication, and injecting them with medications purchased by other patients. They then knowingly billed insurance plans as if Dr. Tan had provided a proper injection to each patient.
The Tans’ health care fraud scheme created significant health risks to the patients and caused a loss of over $12.5 million to more than 10 insurance plans. In addition, the Tans created false tax records to conceal the health care fraud scheme, causing a loss of over $4.2 million to the IRS.
Dr. Tan and her husband were indicted by a federal grand jury in July 2024 and pleaded guilty to one count of health care fraud and one count of tax evasion in November 2025. In 2024 and 2025, the U.S. Attorney’s Office seized approximately $10.4 million in health care fraud proceeds from the Tans.
Dr. Tan’s husband, Daniel Tan, was sentenced to three years’ probation, with two years to be served in home confinement for his role in the fraudulent scheme. The Court ordered Dr. Tan to serve three years on supervised release after her prison sentence.
The case serves as a stark reminder of the importance of honesty and integrity in the medical profession. It also highlights the need for vigilance in detecting and preventing health care fraud schemes.
