If you are scheduling outpatient surgery in Georgia, a Medicare-certified ambulatory surgical center is often the less expensive place to have it. What it costs you is worth pinning down exactly, though, because the ceiling most guides quote does not apply here. Under Medicare Part B, you pay 20% of the Medicare-approved amount to both the surgery center and the doctors who treat you, after the annual Part B deductible of $283 in 2026. One thing to know going in: the well-known rule that a single outpatient copayment can never exceed the $1,736 inpatient hospital deductible is a hospital outpatient payment rule, and it does not govern what you pay at an ASC. This guide explains what you pay at a Georgia ambulatory surgical center, how to compare that cost against a hospital outpatient department before you schedule, the screening-colonoscopy rule most people get wrong, and what changes if you also have Georgia Medicaid.

What Georgia Medicare Covers at an Ambulatory Surgical Center

An ambulatory surgical center is a distinct outpatient facility for same-day surgery that, in most cases, releases patients within 24 hours and does not require a hospital admission. Medicare certifies an ASC separately from a hospital and, under Part B, pays the facility a fee for procedures on Medicare's approved list. The facility fee covers the operating room, nursing, surgical supplies, and equipment used for the procedure.

The single most useful thing to understand before surgery is that one operation produces more than one bill. Medicare's rule is that you pay 20% of the approved amount to both the ambulatory surgical center and the doctor or doctors who treat you, so you receive separate statements and owe cost-sharing on each. For cataract surgery, for example, Medicare's own guidance states you pay 20% to both the facility and the doctor who performs the surgery. Families often read these multiple statements as being charged several times for one surgery; they are not. They are the normal, separate pieces of a single surgical episode.

This is a national Medicare rule, so the coverage itself does not change because you live in Georgia. What the Georgia lens adds is access (finding a Medicare-certified surgery center near you) and, for the many Georgians who also have Medicaid, how the two programs split the cost. Both are covered below.

What You Pay at a Georgia Ambulatory Surgical Center

For most surgery at a Medicare-certified ASC, you pay 20% of the Medicare-approved amount after you meet the annual Part B deductible, which is $283 in 2026., The 20% is your coinsurance on the facility fee, and you owe a separate 20% to the doctors who treat you.

Here is the point most guides get wrong, and it matters most on an expensive surgery. Medicare's familiar ceiling, that the copayment for any one service cannot exceed the inpatient hospital deductible of $1,736 in 2026, comes from the Hospital Outpatient Prospective Payment System at 42 CFR 419.41(c)(4)(i) and section 1833(t)(8)(C)(i) of the Social Security Act. It is a hospital outpatient department rule, and it does not itself govern ASC cost-sharing. At an ambulatory surgical center, plan on 20% of the approved amount with no equivalent per-service ceiling. If the approved facility amount for your procedure came to $12,000, for instance, your 20% would be $2,400, not $1,736. If the exact dollar figure matters to your decision, look the procedure up before you schedule, using the tool in the next section, and ask the surgery center's billing office to confirm your estimated share in writing.

The Part B premium is the entry cost of having the coverage that pays for ASC care at all. The standard premium is $202.90 a month in 2026, and signing up late adds 10% for each full 12-month period you delayed, a penalty generally charged for as long as you have Part B. A Medicare Supplement (Medigap) policy is the usual way to absorb Part B coinsurance, and Georgia offers the federally standardized plans A, B, C, D, F, G, K, L, M, and N, with Plans C and F closed to anyone first eligible for Medicare on or after January 1, 2020. How much of the 20% a plan picks up varies by plan letter, so compare the letters before you buy. Timing matters more in Georgia than in some states: your guaranteed-issue window is the six months beginning the month you are both 65 or older and enrolled in Part B, and Georgia has no annual "birthday rule" or other yearly guaranteed-issue window to switch later, so after those six months an insurer may use medical underwriting and can decline you or charge more.

Cost element Ambulatory surgical center Hospital outpatient department
Coinsurance 20% of the approved amount to the facility and 20% to the doctors, after the $283 Part B deductible 20% to the doctor or other provider, plus a separate hospital copayment for each service; 20% is the baseline, not a ceiling, and a service's rate can run higher
Per-service cap No hospital outpatient copayment cap applies Copayment for any one service capped at the $1,736 inpatient deductible, except at a critical access hospital, where it can be higher
Payment system Separate ASC payment system Hospital Outpatient Prospective Payment System (APC groups)
How to price your procedure Medicare's Procedure Price Lookup shows both settings side by side for the same procedure code Same tool, same procedure code

The two settings are not simply the same percentage on a different base. At an ASC you pay a straight 20% to the facility and to the doctors. In a hospital outpatient department you pay 20% for the provider's services plus a separate hospital copayment per service; that copayment is capped at the $1,736 inpatient deductible (higher at a critical access hospital), and because 20% is the statutory baseline rather than a ceiling, an individual service's coinsurance rate can exceed 20% (federal rules cap an APC's national unadjusted rate at 40%).

Comparing Costs at a Georgia Ambulatory Surgical Center and a Hospital

Your share in either setting is a percentage of whatever Medicare's approved amount is there, and the two settings are paid under separate systems: hospital outpatient departments under the Hospital Outpatient Prospective Payment System, ambulatory surgical centers under the separate ASC payment system, both updated in the same annual rule (for 2026, the OPPS/ASC final rule CMS-1834-FC, issued November 21, 2025). So the answer to "which is cheaper for me" is procedure-specific, not a rule you can apply in advance.

Check it before you schedule rather than assume it. Medicare's Procedure Price Lookup tool shows the national average Medicare payment and your estimated out-of-pocket for the same procedure code at an ambulatory surgical center and at a hospital outpatient department, side by side. Your local Georgia rate will vary somewhat from the national average, so treat the tool's figure as an estimate and ask the facility's billing office to confirm.

The Screening Colonoscopy Rule Most People Get Wrong

A screening colonoscopy is one of the most common procedures done at a Georgia surgery center, and the cost rule trips up almost everyone. When the test is a screening and the provider accepts assignment, you pay nothing, and Medicare sets no minimum age for a screening colonoscopy. But if the doctor finds and removes a polyp or other tissue during that same screening, the visit becomes diagnostic, and you pay 15% of the Medicare-approved amount for the doctor's services in 2026, plus a separate 15% facility coinsurance because the procedure was done at an ambulatory surgical center. The Part B deductible is waived either way. That 15% is a temporary figure on a statutory phase-down at 42 U.S.C. 1395l(dd): Medicare pays 85% for 2023 through 2026 (leaving you 15%) and 90% for 2027 through 2029 (leaving you 10%), and the phase-down applies only to tests furnished before January 1, 2030, so from 2030 these follow-up services go back to $0.

Many guides flatten this to "screening colonoscopies are free," which is true right up until a polyp is removed. Knowing the rule in advance lets you ask the surgery center's billing office how a polyp removal would be coded before the procedure, so a bill does not surprise you afterward. You can confirm the current rule on Medicare's colonoscopy coverage page.

Which Procedures Medicare Covers at a Georgia ASC

Not every procedure is approved for the ASC setting. Covered surgical procedures are limited to those that may be safely performed in an ambulatory surgical center, and CMS publishes and updates that list. If your procedure is not on it, you pay all the facility fees yourself for having it done at an ASC. That is the single question worth asking the surgery center's scheduler: is this procedure on Medicare's ASC covered list.

Separately, Original Medicare does not cover cosmetic surgery in any setting, with a bounded exception: cosmetic surgery is covered when it is required for the prompt repair of accidental injury, or to improve the functioning of a malformed body member. A related trap is the upgraded device: in cataract surgery, Medicare covers a conventional lens implant, but if you choose a premium presbyopia- or astigmatism-correcting lens, you pay the portion of the facility's or physician's charge that exceeds the charge for a conventional lens. Note also how Medicare states the base rule: Part B "may cover cataract surgery that implants conventional intraocular lenses, depending on where you live," which points at local coverage decisions rather than an automatic national yes, so confirm your own procedure with your Medicare Administrative Contractor before you schedule.

Cataract surgery carries a second benefit that is easy to lose at the last step. After surgery that implants an intraocular lens, Part B covers one pair of eyeglasses with standard frames, or one set of contact lenses, which is one of the few times Original Medicare pays for corrective lenses. But Medicare "will only pay for contact lenses or eyeglasses from a supplier that participates in Medicare, whether you or your provider submits the claim." Fill that post-operative prescription at an optical shop that is not enrolled in Medicare and you pay the entire cost, and the one pair you had coming for that surgery is gone. Ask the optical shop whether it participates in Medicare before you order, not after the glasses are made.

If you are in a Medicare Advantage plan instead of Original Medicare, the plan must cover all medically necessary Part A and Part B services that Original Medicare covers, which includes approved ASC surgery. What changes is the access rules: most plans, especially HMOs, generally require you to use in-network providers, except for emergency care, out-of-area urgent care, and temporary out-of-area dialysis, which are covered whether you get them in the plan's network or outside it. A plan may also require prior authorization before it covers a service, which Original Medicare generally does not. Verify the surgery center is in your plan's network, ask whether the procedure needs prior authorization, and ask the plan what your cost-sharing will be, before you schedule.

What Changes If You Also Have Georgia Medicaid

Many older Georgians have both Medicare and Georgia Medicaid. When you are "dually eligible," Medicare pays first and Medicaid is the secondary payer that can cover Medicare premiums and cost-sharing and pay for costs Medicare does not cover or covers only partially, including nursing home care, personal care, and home- and community-based services. For ASC surgery, that means Medicaid is positioned to absorb the 20% coinsurance you would otherwise owe. Note the split: full-benefit duals have Medicare plus full Medicaid, while partial-benefit duals have Medicare plus help only through a Medicare Savings Program, not full Medicaid.

If you are in the Qualified Medicare Beneficiary (QMB) group, federal law prohibits Medicare providers, suppliers, and pharmacies from billing you for Part A and Part B deductibles, coinsurance, or copays at all: you have no legal obligation to pay it, and the prohibition binds all Original Medicare and Medicare Advantage providers, not only those that accept Medicaid. CMS reports that QMBs are still wrongly billed in practice, and a provider who improperly bills a QMB is subject to sanctions and must recall the bill and refund any cost-sharing collected, so if a surgery center bills you, say you are a QMB and ask them to recall it. Georgia administers QMB and the other Medicare Savings Programs through the Division of Family and Children Services, and you can apply through DFCS or online at Georgia Gateway.

Georgians with both programs can also look at a Dual Eligible Special Needs Plan (D-SNP), a Medicare Advantage plan that covers the same Part A and Part B benefits as any other MA plan, adds care coordination, and must include Part D drug coverage; you can stay enrolled only as long as you keep meeting the plan's conditions. Two Georgia-specific caveats: the Georgia Department of Community Health announced a moratorium on contracting with any new D-SNPs starting August 1, 2025, to comply with the federal integration requirements at 42 CFR 422.514(h), with further updates to come; and which SNPs are offered differs from place to place because insurers decide where they do business, so a D-SNP available in one Georgia county may not be offered in the next.

Frequently Asked Questions

Does Medicare cover an ambulatory surgical center, and what does it cost?

Yes. Medicare Part B covers the facility fee for approved procedures at a Medicare-certified ambulatory surgical center. After you meet the $283 Part B deductible in 2026, you generally pay 20% of the Medicare-approved amount to the ASC and 20% to the doctors who treat you.

Is my ASC bill capped at the $1,736 inpatient deductible?

No, and this is a common and expensive misreading. The rule that a copayment for any one service cannot exceed the inpatient hospital deductible ($1,736 in 2026) belongs to the Hospital Outpatient Prospective Payment System, and it does not itself govern ambulatory surgical center cost-sharing. Budget for 20% of the approved amount at an ASC, and price the procedure in advance if it is a large one.

Does the same surgery cost less at an ASC than at a hospital?

Often, but it is procedure-specific: ASCs and hospital outpatient departments are paid under separate Medicare payment systems, so the answer depends on the procedure code rather than on a general rule. Use Medicare's Procedure Price Lookup tool to compare both settings for your specific procedure before you schedule.

Is a screening colonoscopy at a surgery center really free?

The screening itself is $0 when the provider accepts assignment, but if a polyp is found and removed during it, the visit becomes diagnostic and you pay 15% of the Medicare-approved amount for the doctor's services in 2026, plus a separate 15% facility coinsurance at an ASC, with the Part B deductible waived. That share falls to 10% for 2027 through 2029, and the phase-down applies only to tests furnished before January 1, 2030, so from 2030 it returns to $0.

Why did I get separate bills for one surgery?

Medicare pays the ambulatory surgical center and the doctors who treat you separately, and you owe 20% on each. For cataract surgery Medicare states this plainly: you pay 20% to both the facility and the doctor who performs the surgery. They are the normal pieces of a single surgical episode, not duplicate charges.

What if I have both Medicare and Georgia Medicaid?

Medicare pays first and Georgia Medicaid is the secondary payer that can cover your Medicare cost-sharing, including the 20% ASC coinsurance. If you are in the Qualified Medicare Beneficiary group, providers, suppliers, and pharmacies are prohibited by federal law from billing you for Medicare Part A and Part B deductibles, coinsurance, or copays, and that prohibition binds Original Medicare and Medicare Advantage providers alike, not only those that accept Medicaid.
