Medical Call Answering & Medical Call Center - TAS United

## TAS United: Medical Call Answering and Healthcare Call Center Services

TAS United is an US-based call center and telephone answering service that has operated for over 40 years, focused almost entirely on the healthcare sector. Their client base spans solo practitioners, specialty healthcare providers, primary care offices, hospitals, home health and hospice organizations, treatment facilities, and pharmaceutical companies. If your practice cannot afford to miss an after-hours patient call, this is the kind of vendor you put on a shortlist.

### What They Actually Do

The core offering is medical call answering, which means live agents handling inbound patient calls on behalf of healthcare providers, 24 hours a day, 365 days a year. That sounds simple, but the operational detail matters in healthcare because a poorly handled after-hours call is not just a lost opportunity. It is a potential patient safety issue and, depending on what information was shared, a compliance liability.

TAS United's service lines include:

**Medical Answering Services** -- HIPAA-compliant and HITRUST-certified call handling for healthcare practices. This covers message taking, message delivery, urgent call routing, and patient communication on behalf of providers.

**Nurse on Demand** -- a differentiated offering where registered nurses are available to triage and respond to patient inquiries. This is meaningful if your patient population regularly calls with clinical questions that a standard agent cannot safely handle. The research references product recall support as part of this service, which suggests pharmaceutical and clinical operations use cases.

**Bilingual Answering Services** -- English and Spanish coverage. With over 40 million Spanish-speaking residents in the US, this is a real operational gap for practices in high-Hispanic-density markets. TAS United lists this as a named, distinct service, not just an optional add-on.

**Appointment Scheduling** -- live agents scheduling patient appointments on behalf of the provider, which reduces front-desk burden and keeps the schedule moving outside of office hours.

**Virtual Receptionist** -- a broader receptionist function, likely covering call routing, message handling, and basic administrative support for practices that want a more comprehensive front-desk outsourcing arrangement.

**Staff Augmentation** -- the research describes this as having live agents answer product questions and boost sales, which implies a commercial or pharmaceutical use case where TAS United agents supplement an existing internal team rather than fully replacing a function.

**Live Answering Services** -- general live operator coverage including message taking and delivery, positioned as a baseline offering for practices needing overflow or after-hours support.

**Commercial (B2B) Answering Solutions** -- TAS United is not exclusively healthcare. They offer B2B answering services for commercial clients, though their deep specialization and certifications are clearly oriented toward healthcare.

**Secure Technology** -- PCI-certified systems with annual third-party audits, plus HITRUST-certified infrastructure. This is the technical backbone of their compliance posture.

### Compliance and Security Posture

This is where TAS United stands out from a generic answering service. They hold HITRUST certification, which is the most rigorous healthcare information security framework in the US market. HIPAA compliance is the baseline legal requirement; HITRUST is what a serious healthcare operator pursues on top of that to demonstrate they can actually protect PHI (protected health information) operationally, not just on paper. They also carry PCI certification with annual third-party audits, which matters if any payment-related conversations happen on the line.

For any healthcare buyer evaluating a call answering vendor, I would treat HITRUST certification as close to a non-negotiable. A vendor that is only "HIPAA-aware" without independent certification carries more operational and liability risk than the cost savings justify. United Health Group (UHG) is listed as a success story on their site, which, if accurate, suggests they have handled the compliance scrutiny of at least one large payer.

### Who Fits This Vendor

The clearest fit is small to mid-size healthcare practices that need after-hours or overflow call coverage and cannot staff a 24/7 internal team. Specialty providers, primary care offices, home health agencies, and hospice organizations are explicitly listed verticals. Hospitals are also mentioned, though the pitch there is likely overflow or after-hours support rather than a full call center replacement.

Pharmaceutical companies appear in the vertical list, and the Nurse on Demand product recall framing suggests TAS United has handled time-sensitive clinical communication work in that space.

For a buyer outside healthcare, the commercial B2B offering exists, but I would evaluate a different vendor first. TAS United's real depth, certifications, and product design are built around healthcare compliance. Applying that infrastructure to a non-regulated B2B answering use case is possible but probably not the most cost-efficient path.

### Delivery Model and Practical Details

TAS United is US-based, which matters for healthcare buyers on two fronts: regulatory comfort and accent/communication consistency for patient-facing calls. Their agents are described as bilingual (English and Spanish). They operate 24/7 and 365 days a year.

Pricing is listed as a page on their site, but the research does not surface specific rates. For an US-based medical answering service with HITRUST certification, I would expect pricing to sit above a generic offshore answering service, and that premium is justified given the compliance overhead. Expect to discuss per-minute, per-call, or monthly plan structures common in the answering service space. Get a clear picture of what happens during volume spikes, how messages are delivered (secure portal, encrypted SMS, pager), and what the escalation path looks like for a clinical emergency call.

### Editor's Take

Forty years in a specialized niche is a credible signal. The combination of HITRUST certification, bilingual agents, a Nurse on Demand triage layer, and explicit healthcare vertical focus puts TAS United in a different category from a generic answering service that claims it can handle medical calls. That certification is not cheap to maintain, and the fact they have sustained it suggests operational seriousness.

What I would verify on a discovery call: the exact HITRUST scope (what systems and processes are in scope), how agent training works for clinical call types, what the real SLA looks like for urgent call escalation, and how messages are delivered in a way that integrates with your EHR or on-call system. Also confirm current agent headcount and what backup coverage looks like if their primary site has an outage. For a 24/7 service, redundancy is not optional.

This is a solid shortlist candidate for a healthcare practice that wants compliance confidence, bilingual coverage, and clinical triage capability without building an internal team.
