Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Guam for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Guam only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Guam (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

This provider’s billing profile is effectively single-payer: Total Medicare revenue is $645.2K while Total Medicaid revenue is none, and the practice appears to rely almost entirely on Medicare beneficiaries for its revenue base. The precomputed top-3 Medicare codes account for 63.7% of this provider's total Medicare revenue, indicating concentration in a small set of services.

The top revenue-driving codes and their descriptions suggest a dermatology practice that combines high-volume office-based medical management with procedural therapies. High counts for 99214 (1.9K claims, $96 avg paid/claim) and 99204 (220 claims, $107 avg paid/claim) indicate frequent moderate-complexity E/M encounters, while 96910 (1.6K claims, $105 avg paid/claim) and procedure codes like 17110 (639 claims, $94 avg paid/claim) show extensive use of phototherapy and lesion-destruction services.

Revenue concentration is pronounced: the three highest-revenue Medicare codes (99214 at $178.7K, 96910 at $172.3K, and 17110 at $60.1K) together produce a majority of Medicare receipts and are explicitly reported to represent 63.7% of total Medicare revenue. This concentration creates operational exposure if demand or reimbursement for these specific E/M, phototherapy, or lesion-destruction services changes.

On competitive standing, this provider is a high-volume outlier for core office visits and phototherapy: 99214 ranks #1731 of 479517 nationally (100th percentile; extreme outlier, far above typical national volume for this code) and 96910 ranks #10 of 560 providers (98th percentile; notably above typical national volume for this code). 17110 also ranks highly at #408 of 19650 (98th percentile; notably above typical national volume), which together suggest the provider is a major national outlier for several dermatology service lines rather than a modest regional participant.

The mix of surgical and reconstructive procedure codes (for example, 15002 $19.5K revenue, 15004 $18.9K revenue, 14020 $17.7K revenue) alongside malignant lesion excision codes (11642, 11603 and related codes) demonstrates capability in more advanced procedural dermatology and skin surgery. These procedure-level revenues, while smaller than the top E/M and phototherapy codes, indicate the practice offers a range of operative services beyond basic office treatments.

Ancillary topical and photodynamic therapy services are a meaningful adjunct to the practice’s offerings: J7308 (71 claims, $307 avg paid/claim, $21.8K revenue) and 96573 (73 claims, $206 avg paid/claim, $15K revenue) reflect use of aminolevulinic acid and light-based procedures, supporting a bundled medical and procedural dermatology model rather than purely consultative care. These codes align with the high 96910 phototherapy volume and reinforce a clinical focus on light- and drug-facilitated skin therapies.

The provider reports a broad E/M code spread but with skew toward mid-level complexity: in addition to very high 99214 volume, 99204 (new patient moderate complexity) is also an outlier (220 claims, $23.5K revenue; ranks #3641 of 227068, 98th percentile; extreme outlier), while lower-level codes such as 99213 and 99211 appear with much smaller volumes. This suggests the practice sees many established Medicare patients for moderate-complexity follow-ups and also a nontrivial number of higher-intensity new-patient visits.

The NPI tenure (enumerated 2010-04-07, ~16 years ago) indicates an established provider presence in TAMUNING, GU; combined with the Medicare-only billing pattern and the high national ranks on several dermatology codes, this suggests a stable, Medicare-focused dermatology practice with regional continuity and national-scale intensity in specific service lines. The absence of any Medicaid billing on file signals little to no involvement in Medicaid patient care within the dataset provided.
