Occurrence vs Claims-Made: The Core Difference
Occurrence
The better option
Covers any incident that occurredduring the policy period — regardless of when the claim is filed. If a patient sues you 3 years after you left a job, you're still covered by the policy that was active when you provided the care.
- No tail coverage needed — ever
- Coverage follows you after you leave
- Simpler, cleaner, less risk
Typical cost: $3,000-$7,000/year
Claims-Made
The cheaper — but riskier — option
Only covers claims filed while the policy is active. If you leave the job and a patient sues a year later, you're NOT covered unless you purchased "tail coverage" (extended reporting period).
- Requires tail coverage when you leave
- Tail costs 1.5-2x annual premium ($5-15K)
- Gap risk if you forget or can't afford tail
Typical cost: $2,000-$5,000/year + tail
Bottom line: Occurrence is always better for the CRNA. Claims-made is cheaper annually but the tail cost can exceed the savings, and the gap risk is real. If your employer provides claims-made only, negotiate for them to pay tail upon any termination.
Tail Coverage Deep Dive
"Tail" (Extended Reporting Period) is the coverage you buy when leaving a claims-made policy. It extends the reporting window indefinitely so that claims from your time at the facility are covered even after the original policy ends.
How much does tail cost?
Typically 1.5-2x your annual premium. If your claims-made policy is $4,000/year, tail is $6,000-$8,000. For high-risk specialties or high-limit policies, tail can exceed $15,000.
Who pays for tail?
This is the critical contract question. Three scenarios: (1) Employer pays tail on any termination — best case. (2) Employer pays only if THEY terminate you — means you pay $6-15K if you resign. (3) Contract is silent — you pay. Always negotiate this BEFORE signing.
When is tail NOT needed?
If you have occurrence coverage. If you move from one claims-made employer to another AND the new policy includes 'nose' or 'prior acts' coverage from your previous employment dates. If you retire permanently and never practice again (but lawsuit statute of limitations hasn't expired, so this is risky).
What if I can't afford tail?
Some carriers offer 'tail financing' — monthly payments instead of lump sum. Some employers provide tail as a benefit. In the worst case, failing to purchase tail leaves you uninsured for claims from your time there. This is a financial catastrophe if a suit is filed.
Coverage Limits
Malpractice policies have two limits: per-occurrence and aggregate.
$1M / $3M
Standard limits (most common)
$1 million per occurrence, $3 million aggregate per year. Adequate for most practice settings and the most common limit required by facilities and credentialing committees.
$2M / $6M
Enhanced limits
Required by some facilities, especially in high-litigation states (FL, NY, CA). Higher premiums but better protection. Consider if you practice independently or do high-risk cases (cardiac, OB, pediatric).
W2 vs 1099: Who Provides Coverage?
W2 Staff
Employer typically provides malpractice coverage as part of your employment package. Verify: (1) coverage limits, (2) occurrence vs claims-made, (3) who pays tail if you leave. Even with employer coverage, some CRNAs carry a personal 'supplemental' policy ($200-$500/yr) for additional protection.
1099 Independent
YOU are responsible for your own malpractice coverage. Budget $3,000-$7,000/year for occurrence coverage. This is a non-negotiable business expense. Some agencies provide coverage for the duration of the assignment — verify limits, type, and what happens between assignments.
Locum/Travel (via agency)
Most agencies provide claims-made coverage for the assignment period. Critical question: who pays tail when the assignment ends? If the agency doesn't cover tail, you accumulate tail liability at every assignment. Negotiate occurrence or agency-paid tail.
