One way to reduce your MAGI would be to purchase a Bronze plan through the exchange (60% actuarial benefit). The Bronze plan qualifies you for an HSA deduction (line 25 on the 1040) which I believe reduces your MAGI.

FYI I called the nevada state insurance exchange and they told me the state will offer no hsa qualified plans over their exchange. They said hsa plans must be pop and the nevada plans are HMO.
