Hub services automation for specialty and infusion drugs

Hub services are the support programs that get a patient started and kept on a specialty or infusion drug: benefit investigation, prior authorization, copay and patient assistance enrollment, and adherence follow-up. Manufacturers fund hubs to shorten time to therapy, and the steps that slow that timeline are the phone-bound ones, especially benefit investigation and copay enrollment. Flexbone automates those calls and writes structured results back so the next step starts without waiting on hold.

What hub services cover

A specialty drug hub coordinates the path from prescription to ongoing therapy. The core steps are benefit investigation to confirm coverage and patient cost, prior authorization to clear the drug with the plan, copay assistance or patient assistance program enrollment to make the drug affordable, and adherence and refill follow-up to keep the patient on therapy. These run across oncology, immunology, and other specialty and infusion categories, and the metric the hub optimizes is time to therapy: the days from referral to first dose. The clinical steps are not the slow part. The calls are.

Benefit investigation: the first bottleneck

Benefit investigation (BI) confirms whether the plan covers the drug, under the medical or pharmacy benefit, and what the patient will owe. It usually requires reaching the payer, often the pharmacy benefit manager, to confirm formulary status, the prior authorization requirement, the site-of-care rules for infusion, and the patient cost share. Because the answer differs by plan and by benefit, BI is repetitive payer calling that has to happen before anything else moves. Flexbone voice agents place the BI calls, capture coverage, the PA requirement, site-of-care rules, and the patient responsibility, and return it as a structured benefit summary instead of a free-text call note.

Copay assistance and PAP enrollment

Once coverage is known, affordability is the next gate. Commercially insured patients are often enrolled in a manufacturer copay program, and uninsured or underinsured patients may qualify for a patient assistance program (PAP) or a foundation grant. Enrollment means submitting the application, confirming eligibility, and following up on status, frequently by phone. A patient who clears PA but stalls on copay enrollment still does not start therapy. Flexbone runs the enrollment follow-up and status calls and tracks each patient through to an active benefit, so affordability does not become the silent delay.

How Flexbone runs hub workflows

Flexbone runs the hub sequence as a connected workflow rather than separate call campaigns. It places benefit investigation calls, submits and tracks prior authorization, drives copay and PAP enrollment to an active status, and handles refill and adherence follow-up, with each step writing structured results back to the hub or specialty pharmacy system. Cases that need a human, such as a foundation closing a fund or a payer requesting clinical detail, are flagged with context attached. The scope is set to the drugs, payers, and programs in your book, and the agents work inside your existing hub platform so the team sees one record per patient.
