Doctor Referral Payouts for Diagnostic Labs: The Complete Guide (2026)

How most labs pay referrers today, and why it leaks

Walk into a busy diagnostic centre and the referral process usually looks the same: a register or an Excel sheet where someone notes which doctor or centre sent which patient, reconstructed at the end of the month, then settled in cash or by bank transfer. It works until it doesn't. The reconstruction is manual, so it is slow and error-prone. The payout is rarely tied back to the specific bills it came from, so when a doctor disputes an amount there is no clean trail to resolve it. Cancellations and refunds after the fact quietly break the numbers. And because it all lives in one person's spreadsheet, it is nobody's audit trail.

The cost of this is not just the hours. It is leakage (payouts that go out on amounts that were later cancelled, or that quietly drift because rounding was done by hand across hundreds of line items) and it is trust. A referrer who cannot see a clear statement for what they were paid, and why, is a referrer who is easy for a competitor to poach.

Tracking vs. settling: the gap in most lab software

Nearly every laboratory information system on the market has a "referral module." Read the fine print and almost all of them do the same thing: they track referrals and produce a commission report. That is a useful start, but it stops one step short of the only step that matters: moving the money. You still export the report, open your banking app, and pay each referrer one by one, then message each of them separately, then hope the amounts match what you actually billed.

The distinction is worth being precise about, because it is the difference between software that saves you a spreadsheet and software that closes the loop:

Tracking tells you what you owe. It is a report.
Settling clears what you owe: one run that computes every payout from the actual bills, produces a statement and receipt per payee, and leaves an audit trail. It is a workflow.

If you are evaluating lab software, this is a concrete question to ask on the demo: "Does it just report the commission, or does it run the payout?" The honest answer separates most of the market from the small number of products that actually settle.

The reconciliation problem: payouts must tie to bills

The reason manual payouts drift is that the payout and the bill live in different places. A commission is only correct if it is derived from the exact tests that were billed, at the rule agreed for that referrer, net of anything cancelled or refunded. When that link is manual, it breaks under load.

The fix is structural: compute the commission at the moment the test is billed, store it against that bill, and let the period's payout be the sum of those stored line items. Then reconciliation is automatic: the total you pay always ties back to the bills it came from, and a cancellation removes its own commission cleanly. It also means your owner view can show net revenue after commissions live, instead of a gross number that flatters you until payout day.

TDS on commissions: Section 194H

Referral and commission payments in India generally fall under Section 194H of the Income-tax Act, which requires the payer to deduct tax at source on commission and brokerage (commonly 10%, subject to the prevailing threshold and rate). If your lab pays commissions, the responsibility to deduct, deposit and report that TDS sits with you, not the referrer.

Practically, that means every payout needs three numbers on record per payee: gross commission, TDS deducted, and net paid. Keep them in an exportable statement so your accountant can reconcile them at filing time and issue the right certificates. You can estimate your monthly commission and TDS with our free calculator. This is one more reason a paid-out amount should never be a hand-typed figure: it should come from a system that can show its working. (This is general information, not tax advice; confirm the current rate and threshold with your accountant.)

Is it legal? The NMC picture, honestly

This is the part that deserves care, because the answer depends entirely on who is paid and for what. Under the Indian Medical Council (Professional Conduct, Etiquette and Ethics) Regulations, 2002 (Regulation 6.4), a registered medical practitioner may not give or receive any commission, kickback or "gratuitous" payment in return for referring, recommending or procuring patients. This so-called "cut practice" is prohibited, and the National Medical Commission, which now oversees medical ethics, has reiterated the position. Paying a prescribing doctor a per-patient cut for sending you tests falls on the wrong side of that line.

Legitimate commercial arrangements are a different thing entirely. A lab paying an outside laboratory for tests it outsourced, a collection centre for the samples it brings in, or a consultant pathologist for reporting work are ordinary business-to-business payments for services rendered, not payments for a referral. The safest posture in every case is the same: a written arrangement, a clear basis for each payment, TDS deducted where applicable, and a complete audit trail. Transparency is not just good ethics; it is what makes an arrangement defensible.

HealthFlow is built to be the transparent side of this: a tool that computes, documents and settles legitimate arrangements with a full record, not a way to obscure a prohibited one. None of the above is legal advice. If referral economics are part of your business, have your specific arrangements reviewed by a professional.

How HealthFlow settles payouts

HealthFlow was built to close the loop the reports leave open. You set a commission rule per test (flat or percentage, per payee) and the commission is computed automatically as each test is billed, stored against that bill in integer paise so nothing rounds away across a busy month. Referring doctors, consultants, collection centres and outside labs are all supported as payees.

At period-end you run a single Pay-Run. It shows every payee and amount before you settle (nothing hidden or estimated), reconciled against the bills the commissions came from. Each payee gets a WhatsApp payslip; you get a printable statement per doctor and a full Excel export for your records and your accountant. Your owner dashboard shows net revenue after commissions, live and per branch. Automatic doctor-referral payouts are part of a higher plan.

Frequently asked questions

Is paying referral commission to doctors legal in India?

It depends entirely on who is paid and for what. Under the Indian Medical Council (Professional Conduct, Etiquette and Ethics) Regulations, 2002 (Regulation 6.4), a registered medical practitioner may not give or receive a commission or kickback in return for referring patients. This "cut practice" is prohibited and now also addressed by the National Medical Commission. Legitimate business-to-business arrangements are different: a lab paying an outside laboratory for outsourced tests, a collection centre for samples it brings in, or a consultant pathologist for reporting work are ordinary commercial payments. The safest position is transparency: a written arrangement, a clear basis for each payment, TDS deducted where applicable, and a full audit trail. This is general information, not legal advice. Get your arrangements reviewed by a professional.

How do diagnostic labs usually pay referring doctors and centres?

Most still do it by hand: a referral register or an Excel sheet, reconstructed at month-end, then cash or a bank transfer with a WhatsApp message or nothing at all. It is slow, error-prone and hard to audit, and it is where disputes and leakage creep in because the payout is never tied back to the actual bills it came from.

Can referral payouts be automated?

Yes. If your lab software computes each commission as tests are billed (a flat or percentage rule per test, per payee) then at period-end a single settlement run can clear every referrer at once, with a statement and receipt for each. HealthFlow does this with its Pay-Run: one run settles referring doctors, consultants, collection centres and outside labs together, with a WhatsApp payslip and an Excel export.

How is TDS handled on referral or commission payments?

Commission and brokerage payments in India generally attract TDS under Section 194H of the Income-tax Act (commonly 10%, subject to the prevailing threshold and rate). The lab making the payment is responsible for deducting, depositing and reporting it. Keep a per-payee statement of gross amount, TDS deducted and net paid so your accountant can reconcile at filing time. An exportable payout statement makes this straightforward.
