ISURGERY, LLC is operating as an ophthalmic ambulatory surgical clinic/center, with its Medicare billing dominated by cataract and intraocular procedures; the largest single code by revenue is 66984 (cataract with intraocular lens insertion) which generated $447.4K and accounts for 43.2% of the provider’s Medicare revenue, and complementary codes for intraocular lens work (66991) and ophthalmic irrigation/medication (J1097) together form the primary clinical footprint. Revenue concentration is high: the precomputed top three Medicare codes account for 86.2% of total Medicare revenue, indicating a focused service line heavily weighted toward cataract surgery and associated intraoperative medications and devices. The provider’s Medicare footprint is material in scale with total Medicare revenue of $998.3K and no Medicaid billing on file; this makes ISURGERY, LLC effectively a single-payer (Medicare-focused) billing entity in the available data. Competitive standing by code is mixed: for 66991 the provider ranks #74 of 1445 (95th percentile), described as notably above typical national volume, suggesting strength in combined cataract plus anterior segment drainage device procedures, while for 66984 it ranks #2667 of 15965 (83rd percentile), indicating typical but unremarkable national volume for routine cataract extraction. The pharmacy/irrigation supply code J1097 shows a substantial contribution ($213.1K, 20.6% of Medicare revenue) with a rank of #108 of 443 (76th percentile), reflecting routine but significant use of intraoperative ophthalmic irrigation/medication that supports the surgical service line. Several secondary ophthalmic and periocular procedures appear in the top codes but at much lower revenue shares (e.g., 67041 $28.9K, 2.8% and 66982 $14.7K, 1.4%), indicating the center performs a limited mix of retina and complex cataract cases in addition to high-volume routine cataract surgery. Tenure is long enough to establish a stable billing history: the NPI was enumerated on 2008-12-11 (~18 years ago), consistent with an established ambulatory surgical practice rather than a new entrant. There are no Medicaid claims on file (none below), so analyses of payer mix, state Medicaid competitiveness, or cross-payer referral patterns cannot be supported from the available billing records and any assessment should treat Medicaid activity as absent in this dataset.
