HRRP Penalties: How Hospitals Are Reducing Readmission Rates
The Hospital Readmissions Reduction Program has penalized over 2,500 hospitals annually since its inception in 2012. CMS publishes excess readmission ratios in the IPPS Final Rule each year. This article examines the specific care transition strategies hospitals have implemented to bring their ratios below 1.0.
CMS calculates an excess readmission ratio (ERR) for each condition by comparing a hospital's 30-day readmission rate against expected rates adjusted for patient age, sex, comorbidities, and frailty. An ERR above 1.0 means the hospital readmits more than expected.
The penalty is applied as a percentage reduction to all Medicare base operating DRG payments for the fiscal year, not just payments for the six covered conditions. Maximum reduction is 3%.
CMS added a peer group adjustment in FY2019 to account for the proportion of dual-eligible (Medicare/Medicaid) patients, after research showed that hospitals serving more low-income patients had systematically higher readmission rates.
Care Transition Strategies That Reduce ERR
Medication reconciliation at discharge with pharmacist review: The Society of Hospital Medicine's Project BOOST found that pharmacist-led reconciliation reduced 30-day readmissions by 20% across 180 hospitals.
Structured post-discharge phone calls within 48 hours: The call must be interactive (not voicemail) and must review medications, warning signs, and follow-up appointments. TCM billing (99495/99496) requires this and provides reimbursement.
Written discharge instructions at a verified reading level: The Joint Commission recommends materials at or below 6th grade reading level. Tools like the Flesch-Kincaid formula (built into Microsoft Word under Review > Editor > Document Stats) can verify this.
Teach-back method: The patient or caregiver explains the care plan back in their own words. The Agency for Healthcare Research and Quality (AHRQ) lists teach-back as an evidence-based practice in its Re-Engineered Discharge (RED) toolkit.
Common Missteps in Readmission Reduction
Focusing only on the six HRRP conditions while ignoring general readmission patterns. High-readmission hospitals typically have systemic discharge process problems, not condition-specific ones.
Relying on post-discharge phone calls alone without verifying that the patient understood the information. A completed call is not the same as confirmed comprehension.
Using generic discharge instruction templates across all patients regardless of health literacy, language, or cognitive status.
Not tracking whether patients actually access or engage with their discharge instructions after leaving the hospital.
How much do HRRP penalties cost a typical hospital?
The average penalty is approximately 0.5% to 0.7% of Medicare base operating payments. For a hospital with $100 million in annual Medicare revenue, that translates to $500,000 to $700,000 per year. Hospitals at the maximum 3% penalty on similar revenue would lose $3 million annually.
Which conditions have the highest readmission rates?
Heart failure consistently has the highest 30-day readmission rate among HRRP conditions, typically around 20% to 22%. COPD follows at 18% to 20%. Hip and knee replacement has the lowest rate among the six conditions at approximately 4% to 5%, though it was added to HRRP specifically because the volume of these procedures makes even low rates costly.
Does HRRP adjust for patient socioeconomic status?
Since FY2019, CMS stratifies hospitals into peer groups based on the proportion of patients dually eligible for Medicare and Medicaid. Hospitals are compared against peers with similar dual-eligible percentages rather than the overall national average. This was added after research by the National Quality Forum found that safety-net hospitals were disproportionately penalized.
