Health inspection rating: ★★★☆☆3/5 · CMS overall rating: 5/5 · how star ratings work →
The health inspection star above is graded on a curve within each state — a set share of each state's facilities gets each star level — so a facility can have few citations and still rate 2–3 stars if others in its state did even better. The overall rating combines that inspection score with staffing and quality measures from resident assessments and claims.

CMS publishes roughly the last three inspection cycles plus recent complaint investigations. Older surveys drop out of the record as new ones are completed — that window is CMS's, not ours. Within it, every citation CMS publishes for this facility is listed here: none excluded.

Hours are per resident per day for the most recent quarter of payroll data in this CMS release (2026-08-01) — the same quarter for every facility — case-mix adjusted by CMS so facilities caring for sicker residents can be compared fairly (same basis as the CMS staffing star). "Top X%" means better than most facilities: more staffing hours, or lower turnover. Raw (unadjusted) reported hours: total 7.99, RN 4.81, weekend 7.14.Comparing with Medicare Care Compare? Care Compare shows the raw figure (7.99 here, displayed there as hours and minutes), not the adjusted one above. Both are correct; they answer different questions. Staffing rating: 5/5.
Quality measures: assessments & claims
Note: CMS combines facility-reported resident assessments (MDS) with claims-based measures. These are different sources from on-site inspection findings. Read the measures alongside inspection and staffing records; a high QM rating does not establish that a home is safe.
Quality measures rating: 5/5 · long-stay residents: —/5 · short-stay residents: 5/5
Costs & payment
Price evidence · separate from quality
No verified facility-specific private-pay price is available in our data for John T Mather Memorial Hosp T C U. CMS inspection and staffing records do not tell us what this home will charge you.
Calculate a stay from a quote you receive
Use a written private-pay quote. This worksheet adds only the amounts you enter; it does not calculate Medicare, Medicaid or insurance benefits.
Formula: (room rate + daily extras) × days + one-time charges. A 30-day scenario is not a calendar-month quote. Refundable deposits, rate changes and charges you omit are not automatically included. Entries are not saved or sent to our server.
Before you compare prices
- Request the room type, effective date and itemized daily rate in writing.
- Ask about therapy, medicines, supplies, care-level charges, deposits, refunds and annual increases.
- Confirm insurance or Medicaid eligibility and bed availability directly; certification alone does not guarantee either.
