This provider is an ophthalmology physician in Rapid City, SD with a long Medicare enrollment history (NPI enumerated ~2006-06-26), indicating roughly 20 years of active participation in Medicare; that tenure supports established clinical volume and continuity of care in the community. Total Medicare revenue across the provider’s lifetime is $753.6K, and there is no Medicaid billing on file, so the practice is effectively single-payer from the data available and Medicare represents the sole recorded public-payer revenue stream. Revenue concentration is high: the top three Medicare codes by revenue account for 63.6% of this provider’s total Medicare revenue, indicating dependence on a small set of services for the majority of Medicare income. The single largest revenue driver is J0178 (aflibercept injection) with $271.5K in revenue (36.0% of Medicare revenue) across 401 claims; this positions the practice strongly in intravitreal anti-VEGF therapy as a core service line rather than broad multispecialty procedural work. Cataract surgery coding (66984) is the second major revenue source at $128.7K (17.1% of Medicare revenue) across 523 claims, and related intraocular lens/ancillary cataract codes (e.g., 66821, 66991, 66982) also appear in the top 25, which together suggest a mixed medical-surgical ophthalmology practice with substantial cataract procedural volume alongside retinal injection services. Competitive standing by code shows mostly typical, unremarkable national volumes: J0178 ranks #2126/3204 (34th percentile) and 66984 ranks #2838/15965 (82nd percentile), indicating the provider runs above-typical cataract procedural volume nationally but only modest-to-typical volume for aflibercept injections relative to peers. One code is flagged as notably above typical national volume: 99204 (new patient E/M) is described as “notably above typical national volume” and ranks in the 96th percentile, suggesting this provider sees a higher-than-typical number of extended new-patient office evaluations compared with national peers, which may reflect referral intake or practice marketing to new patients. Several imaging and diagnostic codes (92134, 92136, 92133, 92014, 92012) appear among the top billed services, indicating routine use of retinal imaging and comprehensive ophthalmic exams as part of workflow; 92134 and 92136 both sit at high national percentiles (90th) which supports strong in-office diagnostic throughput. Absence of any Medicaid billing means competitive analysis and payer-mix assessment is limited to Medicare activity; there is no in-state Medicaid footprint to evaluate for market share or state-level dominance.
