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.

Key Findings

PEI-CHANG LIU is enumerated as an NPI since 2009-10-05 (~17 years ago) and is listed as a Hospitalist Physician in DEDEDO, GU. Lifetime Medicare revenue for this provider is $40.9K and there is no Medicaid billing on file, making the provider effectively single-payer (Medicare) in the available data set.

Revenue is highly concentrated in a small set of critical and inpatient E/M services: the precomputed top three Medicare codes account for 92.1% of this provider's Medicare revenue. Specifically, 99291 accounts for $31.8K (77.7% of Medicare revenue), 99233 accounts for $3.6K (8.8%), and 99213 accounts for $2.3K (5.6%).

The procedure mix indicates a hospital-centered practice with heavy emphasis on high-intensity critical care and inpatient follow-up. The dominant code 99291 describes critical care services (first 30–74 minutes), supported by 99233 (subsequent hospital inpatient care) and supplemented by lower-intensity office/outpatient visits like 99213; this pattern is consistent with hospitalist activity delivering acute inpatient and critical care management.

Despite the large share of revenue coming from 99291, the dataset characterizes volumes for the top codes as typical and not exceptional: 99291 is listed as #5519 of 71290 providers nationally (92th percentile; typical, unremarkable volume for this code), while 99233 and 99213 rank in lower national percentiles (#95530 of 128818, 25th percentile; #343618 of 457151, 24th percentile) and are also described as typical, unremarkable volume. These labels suggest the provider’s 99291 activity is notable within its own small revenue base but overall volumes remain within routine ranges when compared to national peers.

The absolute scale of billing is modest: total Medicare revenue is $40.9K and the single dominant code 99291 generated $31.8K across 188 claims, indicating most Medicare dollars derive from a limited set of higher-intensity encounters. For payers and network managers, this profile signals a small-billing inpatient/critical-care contributor rather than a high-revenue multi-service facility.

Although mostly inpatient-focused, the provider shows some outpatient and preventive activity: 99203 generated $1.8K (4.3% of Medicare revenue) over 21 claims, 99214 generated $1.1K (2.6%) over 11 claims, and G0008 (influenza vaccine) contributed $396 (1.0%). These smaller line items indicate occasional new/established outpatient visits and preventive care are part of the mix but are minor contributors to total revenue.

The lack of any Medicaid billing on file (none below) means this provider’s exposure and negotiating leverage are concentrated entirely in the Medicare channel. Payers should treat this entity as a Medicare-centric hospitalist with concentrated critical-care billing and limited breadth in Medicaid or other public payer activity.
