Family practices, internal medicine groups, hospitalist teams and multispecialty physician groups all watch the same dashboard: denial rate, clean-claim rate, days in A/R. Those numbers can look excellent while serious money leaves the practice every month. The reason is structural. Denials generate a work queue, so denials get worked. The five losses below never generate one.
1. Split/Shared Inpatient Visits Paying at 85%
In hospitalist and inpatient medicine groups, a physician and an advanced practice provider often see the same patient on the same day. Under the split/shared visit rules, the encounter bills under whoever performed the substantive portion of the visit. When the documentation does not clearly support the physician as the substantive provider, the visit goes out under the APP NPI at 85% of the physician fee schedule.
The claim pays. Nothing denies. Nobody appeals, because there is nothing to appeal. It is a 15% haircut applied encounter by encounter across a daily census. The check: trend the percentage of E/M encounters billed under APP NPIs versus physician NPIs, monthly, by site. If that ratio moved when your staffing model or documentation workflow changed, the ratio is the money.
2. HCC Recapture: Conditions That Fall Out of the Risk Score
For groups with Medicare Advantage or ACO revenue, chronic conditions do not carry forward. A diabetic with complications, a patient with CHF, a patient with COPD – each condition must be assessed, documented to specificity, and coded again every calendar year, or it drops out of the patient risk adjustment factor. The clinical reality has not changed. The RAF has, and the capitation or shared-savings payment falls twelve months later in a settlement that looks completely normal.
The metric is recapture rate: of the conditions coded last year, what percentage were re-documented this year, by physician. Groups measuring it for the first time typically land in the 70s. Every point is real revenue at scale.
3. TCM and CCM: Work Performed, Never Billed
Transitional care management (99495/99496) pays well for something most primary care offices already do: call the patient within two business days of discharge and see them within 7 or 14 days. Chronic care management (99490, with 99439 add-ons) pays monthly for 20 minutes of non-face-to-face clinical staff time your nurses already spend on refills, coordination and calls.
When nobody tracks discharges against the calendar or logs staff time against patients, no claim is ever created. These losses are invisible to every billing report, because the billing system was never told the work happened. First check: count TCM claims in the last 12 months against the discharges your practice knows about.
4. The AWV Plus the Same-Day Problem Visit
A Medicare patient comes in for an Annual Wellness Visit (G0438/G0439) and mentions their knee, or their blood pressure needs a medication change. That is two billable services: the AWV and a problem-oriented E/M with modifier 25. Most groups bill one – usually whichever the front desk or the physician is in the habit of entering. Two things to count: AWVs billed against the eligible Medicare panel, and the percentage of AWVs with a same-day E/M attached. If the second is near zero, the work is being done and given away.
5. Enrollment Lag on New Physicians
A new physician payer enrollment becomes effective 60 to 150 days after their start date, depending on the payer. In the gap, the practice holds claims and risks timely filing, bills incident-to where it often does not apply, or lets claims deny and rebills. The loss books as timely-filing write-offs, adjustments and bad debt – categories reviewed in aggregate, rarely traced to a cause. The measure that exposes it: days from physician start date to first paid claim, by payer, for every provider added in the last two years.
The One Metric That Cannot Be Fooled
Every mechanism above is invisible to denial reporting. The metric that catches all five is paid dollars per work RVU, by payer, trended over 24 months. The denominator is the work your physicians actually performed, so it cannot be flattered by a stale contract file, a suppressed claim, or a silent repricing. When paid-per-wRVU drifts down while denial rate holds steady, the loss is one of the five above.
