The Medicare Prescription Drug, Improvement, and Modernization Act, also called the Medicare Modernization Act or MMA, is a federal law of the United States, enacted in 2003. It produced the largest overhaul of Medicare in the public health program's 38 year history. The MMA was signed by President George W. Bush on December 8, 2003, after passing in Congress by a close margin.

Beginning in 2006, a prescription drug benefit called Medicare Part D was made available. Coverage is available only through insurance companies and HMOs, and is voluntary. Enrollees paid the following initial costs for the initial benefits: a minimum monthly premium of $24.80 (premiums may vary), a $180 to $265 annual deductible, 25% (or approximate flat copay) of full drug costs up to $2,400. After the initial coverage limit is met, a period commonly referred to as the "Donut Hole" begins when an enrollee may be responsible for the insurance company's negotiated price of the drug, less than the retail price without insurance. The Affordable Care Act, also commonly known as "Obamacare", modified this measure.

With the passage of the Balanced Budget Act of 1997, Medicare beneficiaries were given the option to receive their Medicare benefits through private health insurance plans, instead of through the Original Medicare plan (Parts A and B). These programs were known as "Medicare+Choice" or "Part C" plans. Pursuant to the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, the compensation and business practices for insurers that offer these plans changed, and "Medicare+Choice" plans became known as "Medicare Advantage" (MA) plans. In addition to offering comparable coverage to Part A and Part B, Medicare Advantage plans may also offer Part D coverage.

The MMA created a new Health Savings Account statute that replaced and expanded the previous Medical Savings Account law by expanding allowable contributions and employer participation. After the first 10 years over 12 million Americans were enrolled in HSAs (AHIP;EBRI).

Initially, the net cost of the program was projected at $400 billion for the ten year period between 2004 and 2013. Administration official Thomas Scully instructed analyst Richard Foster not to tell Congress of Foster's finding that the cost would actually be over $500 billion. One month after passage, the administration estimated that the net cost of the program over the period between 2006 (the first year the program started paying benefits) and 2015 would be $534 billion. As of February 2009, the projected net cost of the program over the 2006 to 2015 period was $549.2 billion.

After the enactment of Medicare Prescription Drug, Improvement, and Modernization Act in 2003, only insurance companies administering Medicare prescription drug program, not Medicare, had the legal right to negotiate drug prices directly with drug manufacturers. The Medicare Prescription Drug Act expressly prohibited Medicare from negotiating bulk prescription drug prices. The "donut hole" provision of the Patient Protection and Affordable Care Act of 2010 was an attempt to correct the issue. In 2022, the Inflation Reduction Act removed this ban and allowed Medicare to begin negotiating drug prices starting in 2026.
