What is Medical Stop Loss?
Medical stop loss is an insurance product designed to protect employers and plan sponsors who self-fund employee health benefits. It reimburses large, unexpected medical claims that exceed a preset deductible or attachment point. This coverage is sometimes called excess stop loss and sits above the employer’s plan to limit financial exposure from catastrophic claims.
Who needs it
Organizations that offer a self-funded health plan — from small employers to larger associations and multiemployer funds — commonly buy stop loss to stabilize budgeting and protect cash flow. Groups with volatile claim patterns, high-cost members, or limited reserves are typical buyers. Trade groups, clubs, and third‑party administrators may also evaluate stop loss when managing pooled or level‑funded arrangements.
What it typically covers
Stop loss generally covers individual high-dollar medical claims above the individual attachment point and, in aggregate policies, total plan costs above a plan-level threshold. Covered claim types often include inpatient hospital stays, outpatient surgeries, specialty drugs, catastrophic trauma, and extended treatments. Policies vary, so buyers should review underwriting factors and covered services carefully.
Common exclusions or limitations
Most policies exclude routine preventive care costs and pre-existing condition carve-outs may apply during initial policy periods. Mental health and substance use treatments, experimental therapies, fertility services, and some prescription drug costs can have specific limits or separate sub-limits. Contracts often include waiting periods, claim run‑out terms, and exclusions for certain types of providers or services.
Factors that influence cost
Premiums and attachment points depend on employee demographics, aggregate past claims, plan design, stop loss attachment levels, and industry or geographic risk. Other underwriting factors include prior loss history, stop loss provider capacity, and any network agreements. Because prescription drug trends and specialty therapies affect exposure, carriers may adjust pricing accordingly.
Proof of insurance & compliance
Providers or stop loss carriers commonly issue certificates or evidence of coverage that employers use for vendor contracts, third‑party administrators, or regulatory record keeping. Proof of stop loss can be important when demonstrating that an employer has financial protection in place for a self-insured plan.

Risk scenario example: a single catastrophic transplant or extended ICU stay can quickly exceed an employer’s stop loss attachment point, which illustrates why many self-funded plans pair stop loss with active claims management and network strategies.
Frequently Asked Questions
How does individual stop loss differ from aggregate stop loss?
Individual stop loss reimburses large claims for a single covered person above an attachment point, while aggregate stop loss reimburses when total plan claims exceed a predetermined percentage of expected claims.
Can a new self-funded plan get stop loss immediately?
New plans may obtain stop loss, but carriers often review prior coverage, run‑out protections, and initial waiting periods. Underwriting and eligibility rules vary by carrier.
Will stop loss cover all medical expenses?
No. Stop loss is designed for unexpected, high-dollar claims. Routine care, elective treatments, and some specialized services may be limited or excluded depending on the policy.
