Under the Medicare Modernization Act, which aspect of healthcare billings was significantly influenced?

The Medicare Modernization Act (MMA), enacted in 2003, was pivotal in shaping various aspects of healthcare, but one of its most significant impacts was on prescription drug coverage. The act led to the creation of Medicare Part D, a program designed to provide beneficiaries with access to prescription drug benefits. This was a landmark change, as it introduced a prescription drug plan to Medicare, which previously did not offer any coverage for outpatient prescription medications.

By offering a structured benefit for medications, the MMA greatly expanded access to pharmaceuticals for countless beneficiaries, helping to manage healthcare costs related to drug therapy. This influence on prescription drug coverage has had lasting effects on patient care and medication adherence, as well as on the financial burdens placed on seniors and individuals with disabilities.

The other options, while relevant concerns in healthcare billing, do not reflect the primary focus of the MMA, which was clearly centered on enhancing prescription drug coverage.
