This provider’s Medicare billing mix is focused on breast imaging and image‑guided procedures plus bone density testing: the top Medicare codes include 76641 (breast ultrasound, $30.4K, 13.8%), 20611 (ultrasound‑guided arthrocentesis, $29.2K, 13.2%), and 77067 (screening mammography, $27.1K, 12.3%). Additional Medicare activity includes high DXA volume under 77080 ($26.7K, 12.1%), and breast biopsy codes such as 19083 ($16.1K), which together indicate an operation that combines diagnostic breast imaging, image‑guided interventions, and musculoskeletal injection services rather than a single narrow niche.
Revenue concentration on Medicare is moderate: the precomputed top‑3 Medicare codes by revenue account for 39.3% of this provider's total Medicare revenue, indicating significant but not extreme dependence on a small set of imaging and procedure codes. The remaining ~60% of Medicare revenue is distributed across a long tail of radiology, procedural, and occasional E/M codes, so the practice shows both concentration in core services and diversification across multiple modalities.
Medicaid billing is effectively concentrated in three exam types: the precomputed top‑3 Medicaid codes by revenue account for 100.0% of this provider's total Medicaid revenue, driven by 76856 (pelvic ultrasound, $84, 42.6%), 76830 (transvaginal ultrasound, $81, 41.1%), and 71046 (chest X‑ray, $32, 16.2%). In absolute dollars that Medicaid footprint is very small ($184 total Medicaid revenue), so the provider is functionally Medicare‑dominated despite having a full set of listed Medicaid codes.
Payer mix is heavily skewed to Medicare: total Medicare revenue is $223.2K versus total Medicaid revenue of $184, so Medicare represents the overwhelming share of billed and paid activity. The Medicaid data point set is minimal in scale and concentrated in a few low‑dollar ultrasound and radiograph services, which suggests limited engagement with the Medicaid population or low Medicaid reimbursement levels for the services billed.
Competitive standing by code is mixed: on Medicare the provider ranks at or above high national percentiles for several core services — for example, 77080 ranks #702 of 17308 providers nationally (96th percentile; notably above typical national volume) and 20611 ranks #510 of 8465 (94th percentile; typical, unremarkable volume). At the same time, routine screening mammography 77067 is near the national median (ranks #7841 of 15198, 48th percentile; typical, unremarkable volume), so the provider looks like a regional high‑volume performer for specific modalities (DXA, breast ultrasound and ultrasound‑guided procedures) rather than a broadly dominant national mammography center.
State‑level Medicaid comparisons are limited or unavailable for many codes: several Medicaid codes (76856, 76830, 76376) show rank #1 of 1 providers in‑state with no peer comparison available, while 71046 ranks #6 of 8 in‑state (29th percentile; typical, unremarkable volume). These entries plus the tiny Medicaid revenue suggest the provider is not a significant Medicaid competitor in Guam by dollar volume, and many Medicaid observations may reflect sparse state reporting rather than market leadership.
Tenure and operational stability are evident: the NPI was enumerated on 2011-06-22 (~15 years ago), indicating the provider has been active long enough to establish recurring Medicare relationships and develop a stable mix of breast imaging, DXA, and image‑guided musculoskeletal services. That duration aligns with the observed consistent volumes across multiple CPT/HCPCS codes rather than a short‑term fluctuation.
A few statistical and billing patterns merit attention for analysts: J3301 shows a high claim count (826 claims) but very low total revenue ($826, $1 avg paid/claim) and ranks #5276 of 38702 (86th percentile; typical, unremarkable volume), reflecting frequent low‑dollar drug administrations. On the Medicaid side, some codes report claims with $0 average paid/claim (e.g., 76700 and 76376 show $0 avg paid/claim), which may reflect state payment policies, claim adjustments, or reporting artifacts rather than substantive clinical volume; these zero‑dollar Medicaid entries should be interpreted cautiously given the overall $184 Medicaid total.
