Editor's Note: The following are questions received from viewers of "Mad Money," seen every day at 6 p.m. EDT on CNBC.

I own Disney (DIS) - Get Report, EnCana (ECA) - Get Report, Google (GOOG) - Get Report, Schering-Plough (SGP) and L-3 Communications (LLL) - Get Report. Am I diversified?-- George from Utah

James J. Cramer:

A media company, an energy stock, an Internet firm, a drugmaker and a defense contractor -- you are definitely diversified. This is also an enviable group of stocks, and I wish that I owned more than just EnCana for my charitable trust,

ActionAlertsPLUS.

I've heard there will be some changes to the Medicare program next year. What health insurance or other medical stocks are the best way to play this?-- Debbie from Philadelphia

James J. Cramer:

In my opinion, the single best way to play the new Medicare drug plan in 2006 is through

UnitedHealth Group

(UNH) - Get Report

, which I own in my charitable trust,

ActionAlertsPLUS. I believe the company is best-of-breed in the health insurance business, and already has contracts in place with

Walgreens

(WAG)

and AARP to handle their new Medicare prescription needs.
