About the Medicare star rating
CMS (the federal Medicare agency) gives many hospitals an overall rating from 1 to 5 stars, based on measures of mortality, safety, readmissions, patient experience and timely care. It is one piece of information: ask your doctor what matters for your care. See the full Medicare profile →
Medicare quality data
What Kaiser Foundation Hospital - Walnut Creek reported to Medicare (CMS), the federal agency that publishes these results for hospitals nationwide. These are averages for many patients, not a prediction for any one person: ask your doctor what matters for your care. In a medical emergency, call 911.
What patients said (patient survey)
What this means: Patients who stayed overnight answered a national survey (HCAHPS) about their stay. More stars mean patients reported a better experience than at other hospitals. The percentages show how often patients gave the best answer, next to the national average.
| Summary star rating (all survey topics) | 3 of 5 stars |
|---|---|
| Overall rating of the hospital | 3 of 5 stars |

Infections caught in the hospital
What this means: CMS compares the number of infections patients caught in this hospital with the number expected for a hospital like it. The number shown is that ratio: below 1 means fewer infections than expected, above 1 means more. “Better” or “worse” is shown only when the difference is clear in the data.
| Central line bloodstream infections (CLABSI) | 0.797No different from the national benchmark |
|---|---|
| Catheter-associated urinary tract infections (CAUTI) | 1.032No different from the national benchmark |
| Surgical site infections after colon surgery | 1.86No different from the national benchmark |
| Surgical site infections after abdominal hysterectomy | Not reported to Medicare |
| MRSA bloodstream infections | 0.298No different from the national benchmark |
| Clostridioides difficile (C. diff) intestinal infections | 0.2Better than the national benchmark |
Source: Healthcare Associated Infections - Hospital — CMS, released July 22, 2026; data from October 2024 to September 2025.
Complications and deaths
What this means: Death rates are the share of patients who died within 30 days of going into the hospital for that condition, adjusted for how sick they were. PSI-90 combines several serious complications (a lower number is better). “No different from the national rate” is the most common result and means the hospital is in line with hospitals nationwide.
| Deaths within 30 days: heart attack patients | Too few cases to report |
|---|---|
| Deaths within 30 days: heart failure patients | Too few cases to report |
| Deaths within 30 days: pneumonia patients | Too few cases to report |
| Deaths within 30 days: COPD patients | Too few cases to report |
| Deaths within 30 days: stroke patients | 9% |
| Deaths within 30 days: coronary bypass surgery (CABG) | Not reported to Medicare |
| Serious complications (patient safety indicator PSI-90) | 1.14No different from the national rate |
| Complications after hip or knee replacement | Not reported to Medicare |
Source: Complications and Deaths - Hospital — CMS, released September 10, 2026; data from July 2023 to June 2025.
Return visits to the hospital (readmissions)
What this means: The share of patients who had to be admitted to a hospital again within 30 days after going home, adjusted for how sick they were. A lower percentage is better.
| Returned to any hospital within 30 days (all patients) | Not reported to Medicare |
|---|---|
| Readmitted within 30 days: heart attack | 13.6% |
| Readmitted within 30 days: heart failure | 22.9% |
| Readmitted within 30 days: pneumonia | 20.3% |
| Readmitted within 30 days: COPD | 19.6% |
| Readmitted within 30 days: coronary bypass surgery | Not reported to Medicare |
| Readmitted within 30 days: hip or knee replacement | Not reported to Medicare |
Source: Unplanned Hospital Visits - Hospital — CMS, released September 10, 2026; data from July 2023 to June 2025.
Emergency room times and sepsis care
What this means: ER time is the middle (median) time from arriving at the emergency room to leaving it; busier ERs usually have longer times, so the ER volume is shown too. Leaving before being seen: a lower percentage is better. Sepsis is a life-threatening reaction to an infection; a higher percentage means more patients got every recommended early step.
| Average (median) time patients spent in the emergency room before leaving (OP-18b) | Not reported to Medicare |
|---|---|
| Patients who left the emergency room before being seen (OP-22) | Not reported to Medicare |
| Sepsis patients who got all the recommended early care (SEP-1) | 63%National average: 65% |

Prices
Every US hospital must publish its standard charges in a file that follows a federal (CMS) format. Below are 73 common services exactly as Kaiser Foundation Hospital - Walnut Creek lists them in its file. This is not a quote: what you pay depends on your insurance and plan, the doctors involved and the care you actually receive.

In a medical emergency, call 911.
What the prices mean
- Hospital charge
- The hospital’s list price (“gross charge”) before any discount or insurance. Few people pay this amount.
- Cash price

- Hospital and doctor fees
- A service can have a hospital (facility) fee and a separate doctor (professional) fee; the total for your care can include both, plus other services.
