    Key Findings

    KIMBERLY DRENSER is a retina specialist in ROYAL OAK, MI with an NPI enumerated 2006-06-29 (~20 years ago). Her lifetime Medicare revenue is $2.7M and there is no Medicaid billing on file, indicating an effectively single-payer Medicare practice for publicly billed services.

    Revenue is highly concentrated in intravitreal biologic injections: the top 3 Medicare codes by revenue — J2778 (32.5%), J2777 (25.9%), and J0178 (24.4%) — together account for 82.7% of this provider's total Medicare revenue, so changes in utilization or reimbursement for these agents would materially affect overall Medicare income.

    The code mix and volumes indicate an operation centered on chronic intravitreal therapy and retina follow-up care: high revenue claims for J2778, J2777, and J0178 (ranibizumab, faricimab, aflibercept) are supported by procedure and imaging codes such as 67028 (1.6K claims, $157.2K revenue, 5.7%) and 92134 (2K claims, $58.7K revenue, 2.1%), consistent with repeated injections plus diagnostic retinal imaging.

    Competitive standing on the highest-revenue injection is strong: J2778 generates $890.3K (32.5% of Medicare revenue) and the provider ranks #45 of 1208 providers nationally (96th percentile), described in the file as notably above typical national volume for this code, which signals a market-leading position on ranibizumab administration among Medicare peers.

    Other top biologic codes show more typical national positioning: J2777 (24.5K claims, $709.9K revenue, 25.9%) ranks #401 of 2039 providers nationally (80th percentile) and is labeled typical/unremarkable, while J0178 (986 claims, $667.5K revenue, 24.4%) ranks #1299 of 3204 providers nationally (59th percentile) and is likewise reported as typical; these ranks suggest strong revenue contributions but not outlier status for those specific products.

    Office visit billing is an outlier relative to national peers: 99214 appears as 1.6K claims and $150.2K revenue (5.5% of Medicare revenue) and ranks #3104 of 479517 providers nationally (99th percentile; extreme outlier), indicating this provider bills a far higher-than-typical volume of moderate-complexity established-patient E/M visits in Medicare.

    The absence of any Medicaid billing on file means payer mix is effectively concentrated in Medicare, which reduces exposure to Medicaid reimbursement dynamics but also limits diversification of public-payer revenue streams and could affect contracting or network strategy where Medicaid participation is relevant.

    Given the practice’s two-decade tenure (NPI since 2006-06-29) and the dominance of high-cost injectable agents in revenue, the provider appears to operate an established, procedure-oriented retina clinic; this creates both a defensible specialty niche and a sensitivity to drug-specific policy, coverage, or utilization shifts that would disproportionately impact total Medicare revenue.
