If your doctor recommends a pain management procedure like a spinal cord stimulator implant, a pain pump placement, or a nerve block, one of the first decisions you will face is where to have it done. For decades, hospitals were the only option. Today, ambulatory surgery centers (ASCs) handle millions of outpatient procedures every year, and the results may surprise you: lower costs, fewer infections, and shorter wait times.
Schedule a consultation at Kentuckiana Pain Specialists to learn about our on-site ambulatory surgery center and your treatment options.
At Kentuckiana Pain Specialists, patients have access to a Joint Commission-accredited ambulatory surgery center right in the same building where they receive their consultations and follow-up care. Dr. Ajith Nair has performed hundreds of device implantation procedures in this setting over a career spanning more than 30 years.
What Is an Ambulatory Surgery Center?
An ambulatory surgery center is a licensed medical facility designed specifically for outpatient surgical procedures. Patients arrive, have their procedure, and go home the same day. Unlike hospitals, ASCs do not have overnight beds or emergency departments. They focus entirely on planned, same-day procedures.
According to the Ambulatory Surgery Center Association, there are more than 6,100 Medicare-certified ASCs across the United States, and they perform an estimated 28 million procedures annually. Pain management procedures are among the most common categories performed in ASCs.
ASCs must meet strict federal and state regulations. The Centers for Medicare and Medicaid Services (CMS) certify ASCs under 42 CFR Part 416, requiring compliance with standards covering patient safety, infection control, staffing, and equipment. Many ASCs also pursue voluntary accreditation from organizations like the Joint Commission, which is the gold standard for healthcare quality and safety in the United States.
How Do ASCs and Hospitals Compare for Pain Procedures?
When it comes to pain management procedures, ASCs and hospitals differ in several important ways. Here is how they stack up across the factors that matter most to patients.
| Factor | Ambulatory Surgery Center | Hospital Outpatient Department |
|---|---|---|
| Cost to patient | 45-60% lower on average | Higher due to facility fees |
| Infection rate | Roughly 50% lower | Higher exposure to hospital-acquired infections |
| Wait time to schedule | Days to weeks | Weeks to months |
| Procedure wait on day of | Minimal (dedicated surgical schedule) | Potential delays from ER cases |
| Environment | Smaller, quieter, patient-focused | Larger, busier, shared with ER and inpatient |
| Staff specialization | Focused on outpatient surgical care | General across many departments |
| Overnight capability | Same-day discharge only | Available if complications arise |
Why Are ASC Procedures Less Expensive?
The cost difference between ASCs and hospitals is significant, and it comes down to how the two facilities operate and bill for services.
Hospitals charge a facility fee on top of the surgeon’s fee and anesthesia charges. This facility fee covers the overhead of running a large institution with emergency rooms, intensive care units, and 24-hour staffing. According to a 2023 analysis by the Medicare Payment Advisory Commission (MedPAC), Medicare pays hospitals roughly 80% more than ASCs for the same outpatient procedures.
ASCs have lower overhead because they are designed for efficiency. Without emergency departments, inpatient beds, and the administrative layers of a hospital, ASCs can deliver the same procedure at a fraction of the cost. For patients with high-deductible insurance plans or significant copay obligations, this difference can save hundreds or even thousands of dollars per procedure.
At Kentuckiana Pain Specialists, the on-site ASC passes these savings on to patients. Procedures like spinal cord stimulation implants, intrathecal pain pump placements, and radiofrequency ablation can all be performed on-site, avoiding the higher hospital facility fees.
Are Ambulatory Surgery Centers Safe?
Safety is often the first concern patients raise when they learn about ASCs. The data is reassuring.
A study published in the journal Surgery found that ASCs have infection rates approximately 50% lower than hospital outpatient departments for comparable procedures. Several factors contribute to this difference:
- No exposure to hospital-acquired infections. Hospitals treat patients with serious infectious diseases, drug-resistant bacteria, and compromised immune systems. ASCs see only healthy outpatient surgical candidates, which reduces the overall infection risk in the facility.
- Focused cleaning protocols. ASCs handle a predictable volume of same-day procedures, allowing staff to maintain strict sterilization standards between each case.
- Shorter facility time. Patients spend less time in an ASC than they would in a hospital, which reduces exposure to potential pathogens.
The Joint Commission accreditation that Kentuckiana Pain Specialists’ ASC holds is an additional layer of safety assurance. Joint Commission surveys evaluate infection prevention, medication management, patient rights, emergency protocols, and dozens of other quality indicators. Accredited facilities undergo rigorous triennial reviews to maintain their standing.

What Pain Procedures Can Be Done in an ASC?
Most outpatient pain management procedures can be safely performed in an ambulatory surgery center. At Kentuckiana Pain Specialists, the on-site ASC handles a full range of interventional pain procedures, including:
- Spinal cord stimulator trials and implants for chronic back pain, failed back surgery syndrome, complex regional pain syndrome, and diabetic neuropathy
- Intrathecal pain pump implantation for patients who need targeted drug delivery directly to the spinal fluid
- Radiofrequency ablation for facet joint pain, sacroiliac joint pain, and other nerve-mediated conditions
- Epidural steroid injections for herniated discs, spinal stenosis, and radiculopathy
- Nerve blocks including sympathetic nerve blocks, facet joint blocks, and peripheral nerve blocks
The types of procedures that generally require a hospital setting are those involving significant blood loss risk, patients with serious medical conditions that may need overnight monitoring, or complex surgeries expected to last many hours. For the majority of interventional pain management procedures, an ASC is not only appropriate but often preferable.
Shorter Wait Times and a Better Patient Experience
Hospitals juggle surgical schedules alongside emergency cases, trauma patients, and inpatient procedures. This means your scheduled outpatient procedure can be delayed or bumped if more urgent cases come in. ASCs do not have this problem because they only handle planned, same-day cases.
The scheduling advantages extend beyond the day of the procedure. Hospital surgical slots for non-emergency cases often have wait times measured in weeks or months. ASCs can typically schedule procedures within days to a few weeks, which matters when you are living with chronic pain and ready for treatment.
Patients at Kentuckiana Pain Specialists also benefit from continuity of care. The same physician who manages your consultations and treatment plan also performs your procedure in the same building. There is no need to travel to a separate hospital, register with a new system, or coordinate between multiple facilities.
How to Prepare for a Procedure at an ASC
Preparing for a pain procedure at an ambulatory surgery center is straightforward. Here is a general overview of what to expect before, during, and after your visit:
Before your procedure:
- Your care team will provide specific pre-operative instructions, which typically include fasting guidelines (no food or drink for 8 to 12 hours before the procedure), medication adjustments, and what to wear
- Insurance pre-authorization is handled by the practice. At Kentuckiana Pain Specialists, dedicated authorization specialists verify your benefits and obtain approval before your scheduled date
- You will need to arrange transportation home, since sedation is used for most pain procedures
On the day of your procedure:
- Arrive at the scheduled time. Check-in at an ASC is typically faster than at a hospital because the facility is focused exclusively on surgical patients
- A nurse will review your medical history, confirm your medications, and start an IV if needed
- Your physician performs the procedure, which may take 30 minutes to 2 hours depending on the type
- After the procedure, you will rest in a recovery area while the staff monitors your vital signs and manages any immediate post-procedure discomfort
After going home:
- You will receive written discharge instructions covering activity restrictions, wound care (if applicable), and when to call the office
- Most patients can return to light activities within 24 to 48 hours, though recovery timelines vary by procedure
- A follow-up appointment is typically scheduled within 1 to 2 weeks
What About Insurance Coverage for ASC Procedures?
Medicare, Medicaid, and the vast majority of commercial insurance plans cover procedures performed in accredited ambulatory surgery centers. In fact, many insurance companies prefer ASC settings because the lower facility costs reduce their expenses as well.
Kentuckiana Pain Specialists accepts 17 major commercial insurance carriers, Medicare, Medicaid, and workers’ compensation cases. The practice has insurance authorization specialists on staff who handle pre-approval before your procedure, so you know your coverage situation upfront.
For patients with high-deductible plans, the ASC cost advantage is especially meaningful. When you are responsible for a percentage of the procedure cost, having that total be 45 to 60 percent lower than the hospital alternative can make a real financial difference.
Why Kentuckiana Pain Specialists’ On-Site ASC Stands Out
Not all ASCs are the same. Kentuckiana Pain Specialists’ ambulatory surgery center stands apart for several reasons:
- Joint Commission accreditation certifies that the facility meets the highest national standards for patient safety and quality
- Single-provider continuity means Dr. Nair and his team handle everything from your initial evaluation through your procedure and follow-up care, all under one roof
- Specialized focus on interventional pain procedures means the entire facility, staff, and equipment are optimized for the types of cases they handle daily
- Two locations in Louisville and Radcliff (serving Elizabethtown) give patients in the Kentuckiana region convenient access to ASC-based care
- 30+ years of experience in advanced pain management, with Dr. Nair recognized as one of the region’s leaders in device implantation procedures

Frequently Asked Questions
How long do you stay at an ambulatory surgery center?
Most patients spend 2 to 4 hours at an ASC, including check-in, the procedure itself, and a recovery observation period. You go home the same day. For pain management procedures like spinal cord stimulator implants or pain pump placements, the surgical portion typically takes 1 to 2 hours, with about 30 to 60 minutes of post-procedure monitoring.
Is an ambulatory surgery center safer than a hospital?
For outpatient procedures, ASCs have infection rates roughly 50% lower than hospital outpatient departments. ASCs also have highly focused staff and standardized protocols for the types of procedures they perform. However, hospitals are the better choice for patients with complex medical conditions that may require overnight monitoring or emergency support.
Do I need a referral to have a procedure at an ASC?
At Kentuckiana Pain Specialists, the process starts with a consultation with Dr. Nair. If a procedure is recommended and your insurance is verified, the team schedules it at the on-site ASC. Some insurance plans may require a referral from your primary care physician, and the authorization team can guide you through that process.
What happens if there is a complication during an ASC procedure?
Accredited ASCs are required to have emergency protocols, trained staff, and transfer agreements with nearby hospitals. Serious complications during outpatient pain procedures are rare, but if one occurs, the team can stabilize the patient and transfer to a hospital if needed. The rigorous patient selection process at ASCs helps ensure that only appropriate candidates undergo procedures in this setting.
Can I get the same pain procedures at an ASC that I would at a hospital?
Yes, for the majority of interventional pain management procedures. Spinal cord stimulator implants, pain pump placements, radiofrequency ablation, nerve blocks, and many other pain management treatments are routinely performed in ASCs. The main exceptions are procedures requiring extended anesthesia, patients with high-risk medical conditions, or surgeries with significant bleeding risk.
