An Anchorage rheumatologist’s 15-year scheme to defraud vulnerable patients with chronic diseases while evading millions in taxes exposes the devastating consequences when medical professionals prioritize profit over care, betraying those who trusted them most.
Story Snapshot
- Dr. Claribel Tan sentenced to 6.5 years in federal prison for $12.5 million healthcare fraud and $4.2 million tax evasion spanning 2009-2024
- Patients with rheumatoid arthritis and autoimmune diseases received expired medications, free samples, or underdosed treatments while insurers were billed for full-price expensive injectables
- Federal authorities seized over $10.4 million in fraudulent proceeds, with Dr. Tan surrendering her medical license and paying $6.3 million in restitution
- The scheme billed insurers for 4,829 medication units while purchasing only 369, exploiting patients’ irreversible conditions for financial gain over 15 years
Systematic Betrayal of Trust Spanning 15 Years
Dr. Claribel Tan operated a rheumatology clinic in Anchorage alongside her husband Daniel Tan from 2009 through 2024, treating patients suffering from debilitating autoimmune and musculoskeletal diseases requiring expensive injectable medications. The couple systematically defrauded over 10 insurance plans by administering expired medications, free samples, or drugs purchased by other patients while billing for full-price treatments. Federal prosecutors documented an extreme discrepancy where the clinic billed insurers for 4,829 units of medication despite purchasing only 369 units legitimately. This calculated deception placed vulnerable patients at serious health risk while the Tans enriched themselves through fraudulent reimbursements totaling $12.5 million.
Tax Evasion Compounded Financial Crimes
Beyond exploiting their patients, the Tans engaged in deliberate tax fraud from 2014 through 2021, evading $4.2 million owed to the federal government. Court documents reveal they filed false tax returns for 2014, 2015, and 2017 by overstating business expenses to conceal income generated from their fraudulent billing practices. The couple then escalated their tax crimes by completely failing to file returns for their clinic from 2018 through 2021. Federal authorities executed a search warrant around 2020, prompting brief compliance before the Tans brazenly resumed their illegal activities. This dual criminal enterprise demonstrates a pattern of contempt for both patient welfare and civic obligation, funneling ill-gotten gains into what prosecutors termed their “fraudulent retirement plan.”

Justice Delivered Under Federal Prosecution
Following a federal grand jury indictment in 2024, both defendants pleaded guilty on November 18, 2025, to one count each of healthcare fraud and tax evasion. In early 2026, a federal judge sentenced Dr. Tan to 78 months imprisonment for healthcare fraud with a concurrent 60-month sentence for tax evasion, totaling 6.5 years, plus three years supervised release. Daniel Tan received three years probation including two years home confinement for his role managing clinic billing and operations. The government seized $10.4 million in proceeds from the scheme, and Dr. Tan paid $6.3 million in restitution along with a separate $1.8 million False Claims Act settlement while surrendering her medical license permanently.
Patient Harm Prioritized Over Systemic Theft
U.S. Attorney Michael Heyman emphasized the human cost of the Tans’ crimes, stating their “dangerous deceit is over” after authorities seized their fraudulent retirement plan built on patient suffering. IRS Special Agent Carrie Nordyke highlighted how the couple “let patients suffer for financial gain,” underscoring that tax evasion compounds fraud’s impact on honest taxpayers and vulnerable communities. Patients with conditions like rheumatoid arthritis faced genuine health risks from substandard treatments, potentially allowing irreversible disease progression while believing they received proper care. Anchorage’s limited rheumatology specialists amplified this betrayal, as patients had few alternatives and trusted Dr. Tan with managing debilitating chronic illnesses requiring consistent, properly dosed medications for disease control.
Deterrence for Healthcare Provider Fraud
This case reflects growing federal emphasis on prosecuting medical professionals who exploit reimbursement systems while endangering patients, particularly when combined with tax crimes demonstrating systematic dishonesty. The 15-year duration and brazen resumption after a search warrant reveal an arrogance toward law enforcement that federal authorities clearly sought to punish severely through asset forfeiture and imprisonment. The scheme’s targeting of expensive biologic injectables highlights vulnerabilities in insurer oversight of high-cost treatments, likely prompting stricter auditing protocols in rheumatology and similar specialties. For conservative Americans who value personal responsibility and constitutional limits on government overreach, this case represents legitimate federal prosecution protecting citizens from genuine fraud rather than regulatory harassment, as the Tans’ actions directly harmed individuals and violated basic trust inherent in the doctor-patient relationship through deliberate, prolonged deception for profit.
