For many self-funded employers, hearing that a “laser” has been applied to their stop loss policy can feel alarming. Lasers are often associated with unpredictability, increased exposure, and difficult renewal conversations. In reality, lasers can serve as a strategic risk management tool that helps employers balance cost predictability, long-term affordability, and targeted risk protection when managing high-cost claims. ¹
In stop loss insurance, a laser refers to a specific limitation or exclusion applied to coverage for an individual claimant who has generated, or is expected to generate, exceptionally high medical and/or pharmacy costs. Rather than spreading that risk across the entire plan indefinitely, lasers allow plan sponsors to isolate and manage known high-cost exposure in a more deliberate way. ²
When evaluated thoughtfully and paired with appropriate mitigation strategies, lasers can support more sustainable self-funded plan economics over time.
Real-World Scenario: Evaluating Two Renewal Paths
Consider a 300-life self-funded health plan with a $100,000 specific deductible that currently pays approximately $700,000 annually in stop loss premiums. The employer hires a new employee whose dependent requires ongoing medical treatment and specialty medications with an expected annual cost of $350,000. At renewal, the employer is presented with two distinct stop loss structures:
Option 1: No New Laser Provision with a Rate Cap
Under this structure, the plan’s contract prohibits new lasers and includes a 40% renewal rate cap.
- Renewal increase: 30%
- Total annual premium: $910,000
- Fixed cost increase: $210,000
- Risk profile: Highly predictable, with no additional claimant-specific exposure
This approach offers budget certainty, but it embeds the cost of the high-cost claimant into the premium baseline—potentially long after the claimant’s risk has diminished or terminated.
Option 2: Traditional Laserable Policy
An alternative carrier proposal allows a laser to be applied to the known high-cost claimant.
- Renewal increase: 8%
- Base annual premium: $756,000
- Fixed cost increase: $56,000
- Laser liability: $150,000 potential exposure
- Worst-case total cost: $906,000
This structure introduces some variability, but limits premium inflation and preserves a lower long-term cost baseline if the claimant’s exposure resolves.
Comparing Contract Structures: Cost Timing Matters
No New Laser & Rate Cap Contracts
These contracts typically include a 7–10% premium load to protect against future laser risk.³ While they provide near-term stability, they often result in:
- Permanently higher premium baselines
- High-cost claims being amortized into future renewals
- Reduced flexibility if claimant risk is temporary
Over time, employers may continue paying for risks that no longer exist.
Traditional Laserable Policies
Laserable contracts localize cost impact to the period when risk is present. Actuarial analyses consistently show that large claims often have finite durations, particularly when tied to acute conditions, employment changes, or coverage transitions.⁴
Plan costs may spike temporarily, but baseline costs remain more stable over the long term.
Understanding Claimant Persistence and Natural Risk Resolution
Industry studies indicate that a meaningful percentage of high-cost claimants terminate coverage within 6–18 months, often due to job changes, disability, retirement, or transition to other coverage options.⁵
While COBRA can extend exposure, its cost frequently leads individuals to seek alternatives such as Marketplace coverage, Medicaid, or Medicare when eligible.⁶
This natural attrition is an important factor when evaluating whether permanent premium increases are justified.

Strategic Risk Mitigation Opportunities
Pharmacy Rebates and Sourcing Strategies
High-cost claimants often rely on specialty medications that may qualify for significant manufacturer rebates. These rebates typically materialize 6–12 months after dispensing and can meaningfully offset laser liability.⁷
Additionally, alternative sourcing arrangements—such as limited distribution networks or international sourcing programs—may further reduce net cost.
Specialized Management Programs
Employers can also mitigate high-cost exposure through targeted programs, including:
- Organ transplant carve-out coverage
- Dialysis management programs
- Gene and cell therapy carve-outs for emerging treatments
- Case management, prior authorization, and clinical navigation services
These strategies remove or reduce exposure at the plan level while improving care coordination for affected members.⁸
Risk Management Philosophy
Each employer must assess its comfort with risk variability:
- Risk-averse approach: Higher fixed premiums in exchange for cost certainty
- Strategic approach: Lower baseline costs with controlled, temporary exposure
Neither approach is inherently superior—the optimal strategy depends on financial tolerance, workforce stability, and long-term objectives.

Critical Stop Loss Knowledge Areas
Effective self-funded plan management requires understanding:
- Incurred vs. paid contract provisions
- Run-in, run-out, and gapless coverage
- Rate caps versus traditional laserable structures
- Integration between TPAs, PBMs, and stop loss carriers
Advanced planning also includes evaluating carve-outs, experience refunds, and network and pharmacy strategies that influence overall plan performance.¹⁰
Yes/And: Our Take
Lasers in stop loss insurance are often misunderstood, but they are not inherently negative. When used thoughtfully, lasers can provide employers with flexibility, targeted risk control, and long-term cost efficiency. The key is understanding the trade-off between fixed premium increases and variable exposure—and pairing that understanding with proactive mitigation strategies.
Plan sponsors who work with experienced advisors and take a long-term view of risk can use lasers as one component of a comprehensive self-funded risk management strategy, rather than something to avoid at all costs.
All financial projections and plan design decisions should be reviewed with benefits and legal advisors prior to implementation.
