Digital Health Assessments for Voluntary Benefits: How It Works

Voluntary benefits have a participation problem that nobody has really solved. Employers offer supplemental life, critical illness, accident, and hospital indemnity coverage alongside core benefits during open enrollment. Employees scroll past most of it. The ones who do elect voluntary products often face guarantee issue limits that cap coverage amounts, or they hit simplified underwriting questions that feel like a guessing game for both sides. Digital health assessments are starting to change that equation by giving carriers real physiological data at the moment an employee elects coverage, without adding friction to the enrollment experience. That shift has implications for how voluntary products get priced, how much coverage employees can access, and how carriers think about risk in a segment that has historically relied on thin data.

Why Voluntary Benefits Underwriting Has Stayed So Basic

The voluntary benefits market is growing. The global TPA market reached approximately $517.8 billion in 2025 and is projected to grow at a 5.9% CAGR through 2030, according to Hyde Park Capital's Winter 2026 market report. Mercer's 2025 National Survey found that total health benefit cost per employee is expected to rise 6.5% in 2026, the highest increase since 2010. With 59% of employers planning cost-cutting changes to their plans, voluntary benefits become more attractive as a way to offer employees coverage without absorbing the full cost.

But here is the tension. Most voluntary life and critical illness products either use guarantee issue (no health questions, capped at low face amounts) or simplified issue (a short health questionnaire, slightly higher limits). Full underwriting with paramedical exams does not make economic sense for a $50,000 supplemental life policy. The cost of sending a nurse or scheduling a lab draw eats into margins that are already thin.

So carriers accept less data and price accordingly. Guarantee issue products carry higher per-unit premiums because the carrier is flying blind on health status. Simplified issue questionnaires catch obvious risks but miss a lot. An employee with undiagnosed hypertension or elevated resting heart rate sails through five yes/no questions without triggering anything.

The result is a market stuck between two bad options: expensive full underwriting that does not pencil out for voluntary face amounts, or minimal underwriting that leaves carriers exposed and limits what employees can buy.

Underwriting method	Data collected	Typical face amount limit	Cost to carrier	Risk visibility
Guarantee issue	None	$25,000–$50,000	Zero acquisition cost	Very low
Simplified issue	3–7 health questions	$50,000–$150,000	Minimal	Low to moderate
Full underwriting (paramedical)	Labs, vitals, medical history	$150,000+	$75–$200 per exam	High
Digital health assessment	Real-time HR, HRV, RR, BP indicators	Potentially higher GI/SI limits	$1–$5 per scan	Moderate to high

How Digital Health Assessments Actually Work in This Context

A digital health assessment in the voluntary benefits context works like this: during online enrollment, when an employee elects a voluntary product that would normally be subject to simplified underwriting or a coverage cap, the system prompts a 30- to 60-second smartphone camera scan. The employee holds their phone at face level. Remote photoplethysmography, or rPPG, reads subtle changes in skin color caused by blood pulsing through capillaries beneath the surface. From that video feed, algorithms extract heart rate, heart rate variability, respiratory rate, and blood pressure indicators.

A 2025 review published in PMC examining the scope of rPPG health assessment found that heart rate, HRV, blood pressure, and respiratory rate are the four biomarkers most consistently measured, with heart rate achieving the highest accuracy across studies. The review noted that 81.4% of the bibliography was published between 2015 and 2025, reflecting how quickly the research base has expanded.

A separate clinical validation published in PMC in 2025, testing rPPG pulse rate against ECG across 817 samples, found a mean absolute error of 1.061 bpm and a Pearson correlation of 0.962. Accuracy held across device types, lighting conditions, age groups, and gender. Disease-stratified analysis found no significant effect of conditions like hyperlipidemia or type 2 diabetes on measurement accuracy.

That level of accuracy matters because the voluntary benefits use case does not require the same precision as a full clinical workup. Carriers are not diagnosing anything. They are looking for a quick physiological snapshot that supplements the simplified underwriting questionnaire, giving them enough confidence to extend higher coverage limits without full underwriting costs.

What Changes for Carriers and Employers

For carriers, the math gets interesting. If a digital health assessment costs a fraction of a paramedical exam and takes under a minute during existing enrollment flows, the carrier can afford to screen a much larger portion of applicants. That means three things in practice.

First, guarantee issue limits could increase. With even basic physiological data confirming an applicant falls within normal ranges, a carrier might feel comfortable raising GI limits from $50,000 to $75,000 or $100,000 without changing pricing assumptions. More coverage available without questions means higher participation rates and larger average face amounts.

Second, simplified issue accuracy improves. Adding real-time vitals data to a health questionnaire catches things that self-reported answers miss. Someone with consistently elevated resting heart rate or irregular HRV may warrant a closer look, even if they answered "no" to every health question honestly and accurately. The data supplements rather than replaces the questionnaire.

Third, enrollment completion rates could improve. The EBRI-Lincoln Financial survey from March 2026 found that complexity and education gaps are the primary barriers slowing voluntary benefits adoption. Brokers reported that employees are overwhelmed by insurance jargon and complex plan structures. A 30-second scan is simpler than a five-page health history form. It removes a friction point that currently causes employees to abandon enrollment partway through.

For employers, the value proposition centers on participation. Higher enrollment in voluntary benefits means more employees with coverage, which correlates with workforce stability and reduced out-of-pocket health spending that can affect productivity. Alight's 2024 open enrollment analysis found record digital engagement and growing interest in voluntary benefits, with employees increasingly relying on digital tools to complete enrollment. A health assessment embedded in that digital experience fits naturally.

Voluntary Life and AD&D

This is the most obvious use case. Voluntary life products are the largest voluntary benefits category and the one most affected by underwriting constraints. Digital health assessments allow carriers to offer higher coverage multiples at enrollment without triggering the full underwriting process that causes applicants to drop off.

Critical Illness and Hospital Indemnity

Critical illness products benefit from physiological screening because the conditions they cover, heart attack, stroke, cancer, often correlate with detectable cardiovascular indicators. An applicant with normal resting heart rate, healthy HRV, and stable blood pressure indicators presents a lower near-term critical illness risk. That data point helps carriers price more accurately and potentially offer richer benefits.

Group Disability

Short-term and long-term disability products could use digital health data as a baseline measurement. Establishing a pre-enrollment physiological profile gives carriers a reference point for claims adjudication and helps with return-to-work assessments down the line.

Current Research and Evidence

The VA's pilot usability study on contactless vital signs collection, published in JMIR Formative Research in 2024, tested rPPG through smartphone infrared cameras among veterans and VA providers during telehealth visits. The study confirmed feasibility and user acceptance of camera-based vitals collection in real-world, non-laboratory settings. While that study focused on telehealth rather than insurance, it validated that the technology works when real people use it on their own devices, not just in controlled research environments.

A multicenter clinical trial (NCT07491978) registered on ClinicalTrials.gov is currently validating an AI-based remote photoplethysmography system for vital sign extraction. The study is collecting data across multiple sites to establish clinical-grade accuracy benchmarks for rPPG technology. Results from trials like this will help insurers build the actuarial evidence base needed to formally incorporate digital health assessment data into underwriting guidelines.

The PMC systematic review from 2025 identified several established health outputs from rPPG including heart rate, respiratory rate, HRV, hypertension risk, and mental stress detection. Exploratory outputs included energy levels, sleep quality, and resonant breathing assessment. For voluntary benefits underwriting, the established outputs are what matter right now. The exploratory metrics may become relevant as the technology matures.

The Future of Digital Health Assessments in Voluntary Benefits

The trajectory here follows a pattern familiar to anyone who watched accelerated underwriting move from experimental to mainstream in the individual life market. Early programs relied on electronic health records, prescription histories, and motor vehicle reports to replace paramedical exams for healthy applicants. Carriers started cautiously with tight eligibility criteria and expanded as data validated the approach.

Digital health assessments for voluntary benefits are at the beginning of that same curve. The technology works. The cost structure makes sense. The enrollment integration is straightforward. What remains is the actuarial work: correlating rPPG-derived vitals data with voluntary benefits claims experience to build the mortality and morbidity tables that underwriting actuaries need.

Mercer's survey data showing a 6.5% cost increase in 2026 adds urgency. As employers shift more coverage to the voluntary side to manage costs, the volume of voluntary business grows, and so does the need for smarter underwriting at scale. Carriers that figure out how to use digital health data in voluntary products will be able to offer better coverage at better prices, which means higher participation, which means more premium volume.

The companies developing rPPG technology, including Circadify, are building the tools that make this possible. Circadify's contactless vitals platform is designed to integrate into existing digital enrollment workflows, capturing physiological data in the same session where an employee is already making their benefits elections.

Frequently Asked Questions

What is a digital health assessment for voluntary benefits?

A digital health assessment uses a smartphone camera to measure vital signs like heart rate, heart rate variability, respiratory rate, and blood pressure indicators during benefits enrollment. The technology, called remote photoplethysmography or rPPG, reads micro-changes in facial skin color caused by blood flow. The scan takes 30 to 60 seconds and replaces or supplements traditional health questionnaires used in voluntary benefits underwriting.

Does a digital health assessment replace the need for medical exams?

For voluntary benefits, which typically use guarantee issue or simplified issue underwriting, paramedical exams are rarely required in the first place. Digital health assessments occupy the space between no data and full exams. They give carriers enough physiological information to make more confident underwriting decisions without the cost and friction of lab work or nurse visits.

How accurate are camera-based vital sign measurements?

Clinical validation studies show strong accuracy for core metrics. A 2025 PMC study testing rPPG against ECG across 817 samples found a mean absolute error of 1.061 bpm for heart rate with a Pearson correlation of 0.962. Accuracy remained consistent across different devices, lighting conditions, age groups, and gender. Blood pressure estimation is less mature but is the subject of active clinical trials.

What voluntary benefits products can use digital health assessments?

Voluntary life and AD&D are the most immediate applications, since those products are most constrained by current underwriting limitations. Critical illness, hospital indemnity, and group disability products could also benefit from physiological screening data. The approach works best where carriers currently rely on thin data and would benefit from even a basic physiological snapshot at the point of enrollment.
