How Is Office-Based Cataract Surgery Reimbursed?

Start here, because this is the part surgeons most often get backwards. The surgeon's professional fee for cataract surgery is paid the same in an office-based surgery suite as it is in a hospital or an ambulatory surgery center. Moving a case into your own suite does not reduce what you are paid for performing it.

As a rough order of magnitude, a routine Medicare case means 66984 averaging around $462.60, or one of the complex codes if the documentation genuinely supports it. Treat that as an average rather than a quote, since the actual amount varies by locality and by payor.

What changes is the facility side. A claim from a physician office goes out with place of service 11, and Medicare pays no separate facility fee for that setting. An ASC bills a facility fee under the ASC payment system and a hospital outpatient department bills under OPPS, and neither pathway is open to a suite inside a physician office. That is the whole of the difference, and it is narrower than most surgeons expect.

For most procedures Medicare pays the physician more in the office than in a facility, because the non-facility practice expense RVUs are built to cover the room, the staff and the supplies the practice is providing. That gap is the site-of-service differential, and it is the reason so many procedures migrated into offices. Cataract surgery does not work that way. The cataract codes carry an NA non-facility practice expense indicator on the Physician Fee Schedule, meaning CMS has not priced them for the office setting at all. There is no higher office rate to capture. The surgeon is paid the same professional fee wherever the case is performed.

In an ASC or a hospital, the intraocular lens is packaged into the facility payment. The facility buys the lens, the facility is reimbursed for it, and the surgeon never sees that money.

In an office-based surgery suite there is no facility standing between the surgeon and the lens. The practice supplies the lens, V2632 goes to the A/B MAC on the same claim as the surgical code, and the practice is reimbursed for it. That reimbursement averages around $145.73. Treat it as an average rather than a quote, since it varies by locality and by payor.

So a routine office-based Medicare cataract case reimburses roughly $600 across the two codes, and the spread between the lens reimbursement and what the practice paid for the lens stays with the practice instead of going to a hospital or an ASC. Confirm current rates and any prior authorization requirements with each of your payors, since the lens is adjudicated separately from the surgical code.

The idea of a Medicare payment for office-based surgery is not new, and it has been raised with CMS during Physician Fee Schedule rulemaking, including comments asking the agency to price the cataract codes for the non-facility setting. CMS has not created a facility payment for physician offices and has not removed the NA indicator from the cataract codes. Anyone building a pro forma for an OBS suite should assume the current payment structure holds. A business case that depends on a future rule change is not a business case.

Four places, and the first two are the ones surgeons underestimate. The professional fee, paid in full and unchanged from any other setting. The intraocular lens, which the practice supplies and is reimbursed for rather than a facility. Premium and refractive conversion, which rises when the experience improves. And the procedures that carry a priced non-facility rate and pay materially better in the office than in a facility. Time and throughput sit on top of all four, because a surgeon operating in a room down the hall completes more cases in a day than one commuting to a hospital block and waiting on someone else's turnover. An OBS suite is not a billing strategy. It is an operating and ownership strategy.

The site-of-service differential is real for a great many ophthalmic procedures even though it is absent for cataract. Codes that carry priced non-facility practice expense RVUs pay the physician more when the case is done in the office, because the office is bearing the room, staff and supply cost. Building the case mix for an OBS suite starts with running your own procedure volumes against the current Physician Fee Schedule and separating the codes that carry an NA indicator from the codes that are priced for the non-facility setting. That single exercise will tell you more about whether a suite pencils than any published benchmark.

Most practices that open an office-based suite report that premium and refractive conversion rises on its own, without any change to the counseling script. The explanation practices give is straightforward. The experience is far more personal: the same small team every time, no hospital registration line, no shared waiting room, and a surgeon the patient has already met. A patient receiving a premium experience is more receptive to a premium lens. Conversion is not something Medicare pays for, but for most practices it is the single largest revenue effect of moving cases into the office.

Control of the schedule comes first. A surgeon who owns the room decides how many cases run and when, and never loses a block to a hospital's priorities or waits on someone else's turnover team. Second is throughput: a dedicated ophthalmic room with one flow and one instrument set turns over faster than a shared multi-specialty room. Third is the patient experience, which is what moves conversion. Fourth is staffing, because a fixed and predictable surgical day is far easier to staff than scattered hospital blocks. None of these appear on a fee schedule. All of them appear in the practice's income statement.

How many cases a year will actually move into the room, and are those cases yours to move? What is your premium conversion rate today, and what would a five-point increase be worth over a year? What does your current facility pay you, if anything, and what do you give up by leaving it? Do you have space that works under business occupancy without triggering a change of occupancy classification? And is your space and anesthesia plan within Joint Commission OBS standards, since that sets your air handling and your anesthesia limits? If the case volume is not there, a suite will not create it.
