$1M Professional Liability (E&O) Insurance for Medical Billing Companies

$1M Professional Liability (E&O) is a common contract requirement for medical billing companies that handle claims for practices, hospitals and health plans.

What does a $1M requirement mean for medical billing companies?

Professional Liability (E&O, short for Errors and Omissions) covers claims that a mistake in your services caused a client a financial loss. In a billing services agreement, the clause often reads like this:

• Per claim: the most the policy pays for any one claim. Here, $1M.
• Aggregate: the yearly total for all claims. Here, $2M. A $1M/$1M policy does not meet this sample clause.
• Shared limit: every practice you bill draws from the same aggregate (see Professional Liability (E&O) limits explained).
• Claims-made: the policy covers claims made and reported while it is active. The retroactive date is the earliest work date it covers. Payer audits may look back years, so clauses often ask you to keep coverage after the contract ends.

Who asks medical billing companies for $1M?

You will often see $1M from:

• Physician practices and specialty groups that outsource billing, coding or denial follow-up.
• Behavioral health, physical therapy, dental and chiropractic offices.
• Labs, imaging centers and surgery centers.
• Hospital systems and health plans during vendor onboarding. Some ask for more than $1M (see $2M Professional Liability for medical billing companies).

How is $1M built?

At $1M, the limit is usually one primary policy (the policy that pays first), with no extra layers of coverage stacked on top. Billing companies are often written on a Miscellaneous Professional Liability form, a general form for service firms without their own policy type. Firms that mainly sell billing software may need Technology E&O instead. Licensed clinicians usually buy medical malpractice insurance. A $2M limit gives more room when many practice clients share one aggregate.

Before you accept a $1M quote, check four things:

• Does the policy name coding and billing as covered services?
• How does it treat payer audits and refund demands?
• Does it exclude fines and penalties?
• Does the aggregate match the clause?

A commercial umbrella policy (extra liability coverage that sits over your other policies) almost always excludes professional services, so it will not meet this requirement. Clients usually cannot be added as an additional insured (a party listed on your policy for protection) on Professional Liability. If the contract asks for it, Morrow can ask insurers what they offer when requesting quotes.

What will underwriters ask for?

An underwriter is the person at the insurer who decides whether to offer coverage and on what terms. For billing work, they often ask:

• Your services (coding, claims, payment posting, denials, patient statements), with a rough share of revenue from each.
• Your clients by specialty, your largest client's share of revenue, and your yearly claims volume.
• Coder certifications and how you audit coding accuracy.
• Whether you use subcontractors or offshore staff, and whether you sign business associate agreements (contracts on how you protect patient information).
• Your contracts, prior claims, anything that could become a claim, and your retroactive date.

What affects the cost?

• Service mix. Coding and coding audits may cost more to insure than payment posting or patient statements alone.
• Client specialties and volume. High-dollar specialties, such as surgery or oncology, and more claims volume usually mean bigger possible losses.
• Claims history and subcontractors. Prior claims or heavy outside staffing can raise the price.
• Aggregate and defense terms. $1M/$2M usually costs more than $1M/$1M. Many policies pay defense costs (legal fees) inside the limit, which leaves less for a settlement.

Frequently asked questions

Do I need $1M Professional Liability as a medical billing company?

Often yes, if a client contract requires it. Claims can arise from mistakes in coding or claim filing. These are hypothetical examples, not real cases: a coder applies the wrong codes for months, a payer audit finds it, and the practice blames you for the repayment. Or claims sit unsent past a payer's filing deadline, and the practice seeks its lost revenue.

Does Professional Liability pay when a payer takes money back from my billing client?

Usually not for the repayment itself. Many policies exclude fines, penalties and the return of fees, while the client's claim against you for its losses may be covered. Some policies add limited coverage for billing audits or regulatory proceedings. Ask how a policy handles these before you buy.

Is $1M/$1M enough if my billing contract says $1M/$2M?

No, a $1M/$1M policy does not meet a $1M/$2M requirement. Request new quotes for a $1M/$2M policy. Morrow can request quotes for it and ask insurers to keep your retroactive date (and cover work done before the new policy starts) where the market allows. Many businesses keep their current policy in force until the new one has started, so there is no gap. Report anything that could become a claim to your current carrier before that policy ends.

Does my policy pay when the contract makes me cover the practice's losses?

Not always. Many policies exclude liability you take on by contract beyond what you would owe anyway. See the contractual liability exclusion before you sign.
