Anchorage Doctor Sentenced To Prison In Multi-Million-Dollar Health Care, Tax Fraud Schemes

ANCHORAGE, Alaska - An Anchorage doctor was sentenced today to six and a half years in prison for executing a $12.5 million health care fraud scheme and evading over $4 million in taxes on the profits of their 15-year scheme. Her husband and co-defendant was sentenced to three years' probation, with two years to be served in home confinement for his role in the fraudulent scheme. According to court documents, since 2005, Dr. Claribel Tan, 61, and her husband, Daniel Tan, 70, operated a rheumatology medical clinic in Anchorage. Dr. Tan specialized in the treatment of autoimmune and musculoskeletal diseases, such as rheumatoid arthritis, osteoarthritis and psoriatic arthritis, and prescribed injectable medications to treat those conditions. These conditions are often chronic, degenerative and irreversible, but certain medicines can slow or arrest the progression of such diseases. Mr. Tan performed office and management work for the clinic. As part of their scheme, 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 the Tans did not purchase or administer to patients.
