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 Alaska for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Alaska 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. Alaska (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 is a Mohs-micrographic surgery specialist: the top revenue code is 17311 (Mohs surgery) which alone generates $359.1K and, together with the precomputed top-3 grouping, accounts for 68.7% of the provider's total Medicare revenue. The dominance of 17311 and other procedure codes for lesion excision and repair indicates the practice is procedural and surgically focused rather than primary-care oriented, with Mohs surgery as the central service line.

Revenue concentration is high on Medicare: the precomputed top-3 Medicare codes account for 68.7% of the provider’s total Medicare revenue of $642.7K, indicating a narrow dependence on a few high-revenue procedural codes rather than a broad mix of office E/M services. This level of concentration suggests that changes in reimbursement or referral patterns for Mohs and related procedures would have an outsized impact on overall revenue.

Payer mix is effectively single-payer at the state level: lifetime Medicare revenue is $642.7K while there is no Medicaid billing on file. The absence of Medicaid activity implies the provider’s operations and revenue exposure are concentrated in the Medicare market and commercial/self-pay channels rather than Medicaid.

Competitive standing on key Mohs code 17311 is typical nationally in volume: the provider’s rank for 17311 is #393 of 2969 (87th percentile) which the source characterizes as a typical, unremarkable volume for this code. By contrast, the provider is an extreme outlier on some repair and low-complexity visit codes — for instance, 12052 ranks #13 of 1767 (99th percentile) and 99212 ranks #732 of 99011 (99th percentile) — indicating unusually high national volume for these specific wound-repair and low-level E/M services relative to peers.

Tenure is long-standing: the NPI was enumerated on 2006-06-23 (~20 years ago), signaling two decades of Medicare enrollment and likely sustained practice presence in Anchorage, AK. This extended tenure supports credibility of observed billing patterns as established practice behavior rather than short-term fluctuations.

Procedure mix shows a broad procedural scope beyond Mohs alone: in addition to the primary Mohs codes (17311, 17312, 17313), the top codes list includes a range of wound repair (12052, 13152, 13132, 12032, 12042, 13151, 12053) and destruction/biopsy services (17000, 17003, , ), which together portray a practice performing both complex facial repairs and high-volume lesion destruction/biopsy work. This mix implies the provider manages both definitive oncologic excisions and reconstructive closures, consistent with Mohs surgical practice.

There are notable statistical outliers in specific non-Mohs codes: 12052 (intermediate repair to face/ears/eyelids/nose/lips) and 99212 (low-level established office visit) are flagged as extreme outliers (99th percentile), and 13152 is flagged as notably above typical national volume (95th percentile). These outlier designations suggest above-typical productivity or focused specialization in facial repair work and frequent brief follow-up or procedure-related visits compared with national peers.

Clinical revenue mix skews toward procedural payments rather than E/M: while E/M codes such as 99213 and 99212 appear in the top codes, their combined revenue shares are modest relative to the Mohs and repair codes (e.g., 99213 contributes $29.9K and 99212 contributes $27.6K). This supports an operational model where reimbursement is driven mainly by surgical/procedural activity rather than by office-based evaluation management volumes.
