The Revenue Trail
Sigma is built around a simple principle: money should always be traceable back to the care that earned it. The three-step revenue trail keeps that traceability intact across every patient encounter.1
Visit → Bill
Every patient encounter logged in Sigma automatically generates a visit-linked invoice. Charges are attached at the point of care, so nothing is forgotten between the consultation room and the billing desk.
2
Bill → Claim
Each invoice feeds directly into a claim. Sigma pre-fills claim fields — scheme codes, diagnosis information, authorization numbers, and payer details — from the patient record and the visit data. Your billing team reviews and submits without re-keying anything.
3
Claim → Payment
When the insurer processes the claim, Sigma captures the remittance and matches it to the original claim. Partial payments, rejections, and underpayments are surfaced immediately so your team can act — not discover the problem three months later.
Who Uses Sigma HMIS
Sigma is designed for the clinical operations teams responsible for revenue — not just the people providing care.- Reception staff register patients, record visit details, and ensure demographic and scheme information is captured accurately before the billing cycle begins.
- Billing Staff create and review invoices, prepare and submit insurance claims, and manage claim follow-up when insurers respond with approvals, rejections, or partial payments.
- Claims Staff monitor claim submissions, track statuses through the full claim lifecycle, and handle resubmissions when claims are rejected or returned.
- Finance staff oversee payment reconciliation, review remittance advices, and report on outstanding balances across locations.
- Admin users manage team access and permissions, configure insurer schemes, and have full visibility across all modules and locations.
