Understanding Hospital Readmission Rules and Medicare Coverage

Introduction

Returning to the hospital days or weeks after a recent discharge can raise financial and care coordination questions for Medicare beneficiaries and their families. Hospital readmission—an additional admission to the facility within a short span of time—is common, especially among older adults with complex or multiple medical conditions. Does going back to the hospital restart deductibles? Are there special coverage rules? Here’s a helpful look at Medicare’s approach to readmissions and practical steps you can take to make transitions safer, more affordable, and better coordinated.

What Counts as a Readmission Under Medicare

Under Medicare, a hospital readmission is any subsequent inpatient admission to a hospital—regardless of whether it’s for the same or a new problem—that happens soon after a recent discharge. Readmissions can be "planned" (for scheduled surgeries, therapies, or monitoring) or "unplanned" if symptoms worsen or complications develop after returning home.

Hospitals face specific penalties under Medicare if many former patients return within 30 days for certain diagnosis-related groups (such as heart failure, pneumonia, or surgical infections), based on quality-of-care benchmarks. However, for patients, insurance protection is somewhat more uniform and focuses on meeting your clinical needs and following billing period rules.

Coverage and Timing of Benefit Periods

When you’re admitted as an inpatient, your Medicare Part A hospital benefit period starts on the day you’re admitted and ends when you have not received inpatient hospital (or skilled nursing facility) care for 60 days in a row. A return to the hospital (within 0–60 days) is part of the same benefit period, meaning:

  • You don’t pay a new Part A deductible for the second admission within that ongoing benefit period.
  • All covered hospital days count toward the same benefit-period coinsurance limits.
  • If admitted after the 60-day no-admission gap, a new benefit period begins—and you owe a fresh deductible and get a new covered day count.

Will a Readmission Affect Out-of-Pocket Costs or Supplement Insurance

For most, if you return within 60 days, you are not hit with a repeat deductible, but re-admissions can cause you to burn through available covered days more quickly.:

  • The Part A deductible covers your initial spell of illness or multiple admissions tied closely together (60-days or less apart).
  • Beyond certain covered day amounts (60, then 90, then lifetime reserve days), out-of-pocket coinsurances and costs shift for longer or repetitious stays.
  • Medicare Supplements and Advantage Plans often add extra out-of-pocket maximum protections, and may handle daily charges, multiple admissions, or hospital penalties differently based on plan structure.

Best Steps for Hospital Re-entry Protection

  • Keep medication and symptom logs between admissions—accurate, up-to-date records can describe true urgency and support treatment for avoided complications at re-entry.
  • Contact your primary doctor ASAP upon new or recurring symptoms; they can triage correctly and—where possible—line up outpatient or community supports to head off unneeded admission.
  • If you or your loved one must be readmitted, bring the most recent discharge summary and current drug list. This helps care teams speed up new evaluation and avoid errors.
  • Collaborate with the discharge planner about follow-up: set up promptly scheduled nurse/post-acute visits and get transitional care planning upon exit. These close supports may be protective against premature or unnecessary readmits.
