What 'leakage' actually means, and how big it really is#
Referral or network leakage is the share of in-scope clinical services a practice could perform but instead sends out. Health-system analyses from Sg2, Definitive Healthcare, and Becker's have put leakage at 17–22% of attributable revenue, with PCP-to-specialist out-network referrals as the largest single component. 12
For an independent clinic the dollar size is usually larger, not smaller — there is no employed-specialist safety net catching the referral on the back end.
Leakage is rarely a judgment problem#
When a primary care provider refers out a joint injection, IUD insertion, skin biopsy, or minor derm procedure they are credentialed and trained to perform, the cause is almost never clinical. It is that the schedule template has no add-on slot, the procedure tray is in another room, billing flagged a modifier as denial-prone last quarter, or the provider does not personally benefit from doing it.
Industry surveys consistently show same-day access and supply availability — not skill — as the top drivers of in-house procedure capture. 3
The 9-question checklist#
1. Does each provider have a current, posted list of the in-scope procedures their template can actually accommodate? 2. Are procedure trays and consumables stocked at the point of care, or do they require staff to fetch? 3. Is there at least one same-day add-on slot per session, or does every procedure require a return visit? 4. Has the billing team flagged any of these codes as denial-prone in the last 6 months, and if so, has the documentation template been updated? 5. Does the front desk know which procedures can be quoted, consented, and scheduled same-day without a callback? 6. Is post-procedure documentation templated, or does each provider draft it from scratch? 7. Are NPs and PAs scheduled with enough buffer — and credentialed — to handle add-ons under their own NPI? 8. Has anyone quantified the dollar value of leakage, by procedure, in the last 12 months using actual claims data? 9. Does the provider compensation model reward in-house capture (RVU-based or capture-share), or is it salary-flat and indifferent?
What to do with the answers#
Each 'no' is a 1–4 week operational project, not a hiring decision. In published case studies, simply adding a single same-day procedure slot per provider per session recaptures roughly half of avoidable leakage within a quarter. 4
If question 9 is a 'no', fix it before any of the others. Operational changes do not stick when the comp model is silent on the outcome they are designed to produce.
Quantifying the dollar size for your clinic#
Pull your last 12 months of outbound referrals from the EHR. Categorize each by whether you are credentialed and equipped to perform it. Multiply the captured-eligible volume by your weighted average reimbursement per code. That is your annualized leak.
The Referral leak analysis report does this against your actual data, ranked by dollars and ease-of-fix.

How we write these →Frequently asked
- Isn't leakage sometimes a good thing for patients?
- Yes — out-network referral is correct when a sub-specialist genuinely has better outcomes or when the patient explicitly requests it. The checklist is about the share that happens by accident, not by clinical choice.
- How quickly can in-house capture move?
- Operational fixes (slots, supplies, templates) typically move capture within a quarter. Comp-model changes move it within 2–3 pay cycles. New credentialing for NPs or PAs takes 60–120 days depending on state and payer.
