Lifetime revenue by payer source (source: CMS Medicare & Medicaid claims data)
| Payer Source | Total Paid |
|---|---|
| Medicare | $305.6K |
| Medicaid | $25.4K |
This provider is effectively Medicare‑dominant: total Medicare revenue is $305.6K versus Medicaid revenue of $25.4K, indicating Medicare accounts for the overwhelming share of billed services and revenue. The disparity suggests practice economics and patient mix are driven principally by Medicare beneficiaries rather than Medicaid.
Medicare revenue is highly concentrated: the precomputed top 3 Medicare codes account for 62.5% of Medicare revenue, driven primarily by 66984 ($112.1K, 36.7%), 92014 ($50K, 16.4%), and 99213 ($28.5K, 9.4%). This concentration points to a small number of high‑revenue cataract and office evaluation codes underpinning most Medicare receipts.
Clinical mix and service line implications: the prominence of 66984 alongside supporting codes such as 66821, 66991, and 92136 indicates a procedural emphasis on cataract surgery and intraocular lens services, while substantial volume in 92014/92004 shows ongoing medical ophthalmology follow‑up and comprehensive exams. Together these patterns are consistent with a cataract surgery practice that also maintains routine ophthalmic diagnostic and medical care.
Diagnostic and imaging intensity is above typical national peer levels for several modalities: 92083 (visual field testing) and 92250 (fundus photography) both rank in the top percentiles nationally (92083 listed as 96th percentile and 92250 as 97th percentile, labeled “notably above typical national volume”), and 92133/92134 are also frequent. This suggests the provider performs a higher-than-typical share of visual field and retinal imaging relative to national peers, supporting surgical and medical management workflows.
Competitive standing on surgical codes is modest to typical: 66984 ranks #3001 of 15965 providers nationally (81th percentile; typical, unremarkable volume) and 66821 ranks #2768 of 10087 (72th percentile; typical, unremarkable volume), indicating the provider is not a dominant national cataract surgery outlier but operates at a steady, conventional volume for these procedures. At the same time, select diagnostics (92250, 92083, 92004) are flagged as notably above typical national volume, producing a mixed competitive profile of routine surgical volume paired with stronger-than-typical diagnostic throughput.
Medicaid activity is small and highly concentrated: the precomputed top 3 Medicaid codes account for 78.6% of Medicaid revenue, with 99213 alone representing $13.6K or 53.5% of Medicaid revenue. The Medicaid footprint appears clinic‑visit centric rather than procedural; 99213 ranks #1044 of 2046 in-state (49th percentile; typical, unremarkable volume), indicating middling participation in the state Medicaid market for office visits.
Statewide specialty standing contains niche outcomes: 92145 is listed as #1 of 6 providers in-state (100th percentile; typical, unremarkable volume) but contributes only $186 (0.7% of the provider’s Medicaid revenue), so while the provider appears unique among a small group statewide for that specific service, it is not a material revenue driver. Other Medicaid codes such as 92015 and 92014 produce modest in-state ranks (92015 at #146 of 195, 25th percentile; 92014 at #134 of 194, 31th percentile), reinforcing a modest Medicaid role concentrated in basic ophthalmic examination and refraction services.
Practice tenure and stability: the NPI was enumerated 2006-01-09 (~20 years ago), indicating the provider has an established presence and likely long-term referral and patient relationships in the local market. Combined with the revenue and code mix, the tenure supports interpretation of the patterns as steady operational focus rather than a transient billing profile.
