Pharmacy benefit caps in retiree drug coverage lead to increased medication discontinuation. Few patients restart therapy after caps, highlighting potential access issues for Medicare Part D reforms.

Area of Science:

  • Health Economics
  • Pharmaceutical Policy
  • Retiree Health Benefits

Background:

  • Employer-sponsored drug coverage is crucial for retirees.
  • Annual benefit limits on pharmacy benefits can impact medication access.
  • Understanding medication use patterns under different coverage designs is essential.

Purpose of the Study:

  • To examine medication use among retirees with employer-sponsored drug coverage.
  • To compare medication use with and without annual pharmacy benefit limits.
  • To infer potential impacts on Medicare Part D based on retiree plan similarities.

Main Methods:

  • Analysis of medication use data for retirees.
  • Comparison of discontinuation and reinitiation rates.
  • Assessment of plan switching and generic drug utilization.

Main Results:

  • Pharmacy benefit caps significantly increase medication discontinuation across major therapeutic classes.
  • A small proportion of retirees resume medication after their benefit cap is reached.
  • Plan members reaching their cap are more likely to switch plans and temporarily increase generic use.

Conclusions:

  • Annual pharmacy benefit limits negatively affect medication adherence among retirees.
  • The findings suggest potential challenges for Medicare Part D beneficiaries facing benefit limits.
  • Policy considerations for Medicare Part D may need to address benefit cap impacts on continuous medication therapy.
