You asked for a 150 mile radius of Nashville, so this page counts the hospitals and surgery centers inside it. Kinamed's own site lists orthopedic, cardiothoracic and neurosurgical products, so the page also shows which hospitals had Medicare volume in joint replacement, open heart surgery and cranial surgery. Distances are straight-line miles from downtown Nashville. It counts facilities, not people, and it says nothing about which of them you already sell to.
Hospitals within 150 miles
General acute care, critical access, VA and military hospitals. Psychiatric and rural emergency hospitals are left out, and there are no separate children's hospitals inside the radius.
With Medicare joint replacement volume
Hip, knee and shoulder replacement and revision, 4,300 Medicare discharges in 2024.
Joint replacement, open heart and cranial surgery, all in the same hospital.
Surgery centers within 150 miles
Of those, 39 had enough Medicare orthopedic cases for CMS to publish a result.
Where they are
Hospitals and surgery centers inside the radius, by state.
All hospitals counted adds the VA and military hospitals to the first two columns. Surgery centers are those in CMS's surgery center quality file, 2024 release.
| State | General acute care | Critical access | All hospitals counted | Surgery centers |
|---|
| Tennessee | 53 | 12 | 67 | 81 |
| Kentucky | 21 | 16 | 38 | 9 |
| Alabama | 12 | 2 | 14 | 10 |
| Indiana | 3 | 3 | 6 | 11 |
| Illinois | 1 | 3 | 4 | 1 |
| Georgia | 3 | 0 | 3 | 7 |
| Mississippi | 3 | 0 | 3 | 2 |
| Total | 96 | 36 | 135 | 121 |
Which hospitals do the surgery
Hospitals inside the radius with Medicare inpatient volume in each group, 2024.
Medicare fee-for-service inpatient stays only. Many hip and knee replacements are now done as outpatient cases, and critical access, VA and military hospitals are not in this file at all, so total case volume is higher. CMS publishes a hospital's number for a procedure only when it had 11 or more Medicare discharges, so these counts are a floor.
| Procedure group | Hospitals | Medicare discharges | Hospitals in Tennessee | Hospitals in other states |
|---|
| Hip, knee and shoulder replacement and revision | 50 | 4,300 | 24 | 26 |
| Open heart, valve and bypass surgery | 15 | 1,900 | 9 | 6 |
| Craniotomy and other brain procedures | 12 | 826 | 9 | 3 |
Where the openings sit
50 hospitals with joint replacement volume
Between them, 4,300 Medicare joint replacement and revision discharges in 2024. The people who usually decide here are the orthopedic surgeons, the OR or perioperative director, and the value analysis committee with supply chain.
9 hospitals with all three programs
These hospitals had volume in joint replacement, open heart and cranial surgery. One supplier agreement there can carry orthopedic, cardiothoracic and neurosurgical lines together, though each product usually still goes through value analysis on its own. Add the cardiothoracic surgeons and neurosurgeons to the people above.
39 surgery centers with published orthopedic volume
Surgery centers buy on a shorter path than a hospital, usually through the administrator, the medical director and the surgeon owners.
Ownership
Of the 135 hospitals, 60 are nonprofit, 36 are for-profit and 39 are government owned. These counts do not say which health system or purchasing group each one belongs to.
Denominators, definitions and sources
- Hospitals come from CMS's Hospital General Information file, updated Jul 22, 2026. Each one is placed at the center of its ZIP code area from the Census Bureau's 2024 files. Where the ZIP is a post office box, it is placed at the center of its city. Distances are straight-line, not driving, miles from downtown Nashville.
- Procedure groups are Medicare inpatient discharges for 2024 by hospital and diagnosis related group. Joint covers hip and knee replacement and revision, bilateral joint procedures, shoulder and other upper limb joint replacement, and hip replacement after a fracture. Open heart covers valve and other major cardiothoracic surgery and bypass surgery. Cranial covers craniotomy and the endovascular brain procedures CMS groups with it.
- Surgery centers come from CMS's surgery center quality file (2024 release). A center is counted as doing orthopedic cases when CMS published its measure on hospital visits after orthopedic procedures, which CMS builds from Medicare claims for patients 65 and over. CMS holds back that result for centers with too few such cases, and 26 more centers in the radius fall in that group, so 39 is a floor.
- Each hospital is one CMS provider number, and a few of them cover more than one campus. One hospital listed twice at the same address is counted once. Hospitals near the 150 mile line were placed by street address.
- Discharge figures of 1,000 or more are rounded on purpose.
