Silna Health

Silna works with more than 1,000 payers across 50 states, calling insurers for benefits and authorization status and submitting through their portals. On the provider side it connects to the EHR and practice management systems ABA providers already use, CentralReach and Catalyst among them, so insurance work runs alongside the clinic's existing setup. The list of practice systems is short and centered on ABA platforms, and whether authorization results flow back into them is unclear.

The prior authorization lifecycle runs from expiration tracking and weekly reminders through form generation, submission and continual payer follow up. It branches as requests for additional information or resubmission raise alerts, denials move to appeal and Medicaid plan switches are flagged so authorizations can be resubmitted to the new plan. For ABA the same lifecycle covers initial assessments, concurrent reviews and reauthorizations. Behind it, document validation rules combine with AND and OR logic into configurations, and a graph decides which rules apply to each document type.

Silna maintains an always current database of each payer's prior authorization requirements per specialty, kept by its Payor Intelligence team from payer bulletins and the thousands of authorizations it processes each week, and applies it to form generation and document validation so providers never track the rules themselves. Predictive Document Intelligence reads diagnosis reports, treatment plans and progress notes with multimodal models and checks them against those criteria before submission, ABA treatment plans and progress reports included, and Silna reports a 98 percent first pass acceptance rate for requests it validates.

Staff stay in the loop where judgment matters. When document validation finds a gap against the payer's criteria, the provider reviews it and decides whether to update the documents or submit as they are, and requests for more information, resubmissions and appeals come back to the team as alerts. Behind the agents, Silna sends a set share of submissions to its own QA reviewers, who can override and correct the agent's work. Routine requests go out without staff touching each one, so there is no clinic sign off before a standard submission reaches the payer.

Security starts with SOC 2 Type II certification through Vanta, operation under HIPAA and a pledge to treat patient confidentiality as a priority. On the agent side, each browser session is tied to a single provider through row level security, so one clinic's agent cannot reach another clinic's records. There is no single sign on or role management for a clinic's own staff.

Clinics follow each authorization from submission to approval on a dashboard, with approvals passed along as they arrive. Inside Silna, every inference call and tool execution of a browser agent is saved as a pipeline step and each session gets a quality score from 0 to 100, a record that serves Silna's own engineers and reviewers. Clinics see status and outcomes rather than the agent's step by step trail.

What persists sits on Silna's side: the payer requirements database and the growing record of reviewer corrections that shapes later submissions. The agents work from those shared stores and each authorization's own record, with no memory of a clinic or patient that has its own scope or lifetime.

The service is hosted. Its browser agents operate in sandboxed sessions on Silna's own self hosted Kasm Workspaces deployment, which isolates each session from the next and keeps agent activity off the clinic's own machines. There is no region choice, customer cloud or on premises option.

Silna sells one Care Readiness Platform built from prior authorizations, benefit checks, insurance monitoring and payor discovery, with prior authorizations priced at $35 each. These work as parts of one service rather than separate agents a clinic switches on, and there is no template or agent library. Customers include Behavior One Autism Solutions, Autism Learning Partners, ABS Kids, AnswersNow, HealthPro Heritage and Elite Alliance Physical Therapy.

Work starts without staff: weekly expiration reminders, recurring eligibility and benefit checks, real time monitoring of every active patient's coverage, automatic detection of new insurance and Medicaid plan switches, and phone agents that call payers to check whether a submitted authorization was approved. For ABA, authorized hours remaining and upcoming reauthorization deadlines are tracked continuously so renewals go out before therapy is interrupted.

Models are picked for each payer portal after testing cost, context window, intelligence and speed, and production traffic can be split between models that perform equally, for example half to Haiku 4.5 and half to GPT 5.4. The phone agents use Deepgram for speech recognition and ElevenLabs for speech, and the customer has no choice of model.

Authorizations can be followed from submission to approval through an API as well as Silna's dashboard, which gives a clinic's other systems a way to track them. There is no public API reference, SDK or MCP server, and the agents themselves work through payer portals, payer phone lines and Silna's own app.

An in house Experiments platform sets what share of prior authorizations each portal agent submits with no human touch and routes a share of agent submissions to human QA, comparing human and AI results, and specialist reviewers flag minor or major errors to build a dataset of where the agent was wrong. Models are tested per portal in a sandbox on production infrastructure for duration, token use and accuracy, and every session gets a score from 0 to 100 for execution quality, apart from its final outcome.

Browser agents work payer portals on their own, logging in with 2FA, navigating complex legacy interfaces, entering clinical data and recording approvals, across Blue Cross, Aetna, United and dozens of other portals, inside sandboxed browser sessions. They now handle nearly half of all prior authorizations and are trained to stop and ask for help rather than guess when stuck. Phone agents navigate payer phone menus to retrieve plan details.
