For independent specialty practices

Every referral that goes unread is a patient who never comes back.

Suture reads inbound referral and discharge faxes, pulls out the fields that matter, routes what a human actually needs to see, and chases the patient until the follow-up is on the calendar.


Problem

The fax machine is still the front door.

Independent practices lose referrals in the gap between a PDF landing in a queue and someone finding time to key it in. Suture closes that gap without asking anyone to change how they refer.

Leakage

Referrals that quietly die

A referral sits unopened, the patient goes elsewhere, and nobody finds out for a month. Suture tracks every inbound document to a booked appointment, or flags it as at risk.

Keying

Manual data entry

Name, DOB, payer, member ID, diagnosis codes, referral reason. Extracted automatically, each field scored, and only the uncertain ones put in front of staff.

Prior auth

Payer rules nobody memorized

Whether Highmark or UPMC requires auth for a given CPT code, what documentation the packet needs, and a draft appeal when it comes back denied.

Follow-up

The patient who won't pick up

A cadence across text, email, and voice, with a self-scheduling link, then a confirmation fax back to the hospital that discharged them.


Product

Built, running, and honest about what it is.

Not mockups. These are screens from the working application, taken against a seeded Western PA dataset.

Suture review screen: the referral PDF on the left, extracted fields with per-field confidence scores on the right, and eight fields flagged as not extracted.
ReviewDocument on the left, extracted fields on the right. Every field carries a confidence score, and anything missing is flagged before a human signs off.
Suture inbox listing referral and discharge documents with status, classification, and confidence columns.

Prior authorization detail for Highmark BCBS PA, CPT 93458, showing auth-required status and cited reasoning.

Seeded cardiology data. Same pipeline, aimed at independent specialty practices.


Engineering

Patient data is the whole product. It's built like it.

A HIPAA-class workload built solo, with the load-bearing decisions written down in eleven architecture decision records.

Isolation

Fails closed, not open

Tenant scoping is enforced once at the ORM session layer, not repeated in every query. If the clinic context is missing, the query raises. It does not return unfiltered rows.

PHI

Encrypted at the column

Date of birth, phone, SSN, and insurance member IDs are Fernet-encrypted field by field. The append-only audit trail records who touched what and which columns changed, but never the values.

Models

Local by default, no lock-in

Every model call goes through a provider interface. The default runs entirely on-premise via Ollama; a practice that wants a hosted frontier model brings its own key. No patient record has to leave the building.

Accuracy

Measured, not asserted

Extraction accuracy is scored against a ground-truth corpus (per-field precision, recall, and F1, recorded per run), so a prompt or model change is a diff, not a vibe. Field confidence is computed from validators, never self-reported by the model.

Status
Pre-launch, and specific about it. The full pipeline executes end to end and every step is auditable, but outbound channels currently run against local stubs rather than real carriers. Nothing here has touched a live patient.
