6th Cir.2012Background
- Tasis and co-conspirators operated a sham Dearborn Medical Rehabilitation Center to bill Medicare for infusion therapies not provided.
- They recruited homeless Medicare recipients with HIV, hepatitis, or asthma to obtain insurance IDs and paid them for participation.
- From four months in 2006, the Center billed Medicare about $2.856 million and received roughly $827,000.
- Over 15 months, the scheme caused about $9.122 million in Medicare claims filed.
- Daisy Martinez testified about a Florida scheme; trial court limited her testimony to intent, plan, and knowledge related to the Michigan scheme.
- Tasis was convicted on fraud/conspiracy counts and sentenced to 78 months with restitution totaling about $6.079 million.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Doyle claim preservation and curative instruction | Tasis argues Doyle error warrants new trial | Tasis asserts improper cross-examination without cure | No error; curative instruction cured defect |
| Admission of Florida conspiracy under Rule 404(b) | Evidence relevant to knowledge/intent, not character | Prejudicial spillover; not properly admitted | Affirmed admission for noncharacter purposes (knowledge/intent) |
| Multiple conspiracies jury instruction | Pattern instruction should have been given | Requested instruction unnecessary; district court gave adequate guidance | Court's instruction adequately confined to Michigan conspiracy; no abuse |
| Rule 403 balancing obligation | Court should balance probative value vs. prejudice | District court failed to balance | Not reversible; no objection and implicit balancing occurred |
