Here's a list of what has been done in the state of Massachusetts (where I live) with regards to medical liability reform:

Medical Liability Reform: Collateral Source Reform: Mass. Gen. Laws Ann. Ch. 231 § 60-G.  Provides for awards to be offset by collateral sources, less any premiums paid by the claimant to secure those benefits.

Medical Liability Reform: Contingent Fee Reform: Mass. Gen. Laws Ann. Ch. 231 § 60-I.  Limits contingent fees in medical liability cases to 40% of the first $150,000 recovered, 33.3% of the next $150,000 recovered, 30% of the next $200,000 recovered, and 25% of any amount over $500,000 recovered.

Medical Liability Reform: Noneconomic Damages Reform: Mass. Gen. Laws Ann. Ch. 231 § 60-H.  Limits noneconomic damages in medical liability cases to $500,000, unless the claimant can show “a substantial or permanent loss or impairment of a bodily function or substantial disfigurement.”

Medical Liability Reform:  Periodic Payment of Future Damages: Mass. Gen. Laws Ann. Ch. 231 § 60-F.  Requires juries to state in the verdict what portion of the award is for future damages, but does not provide for periodic payments.
