How Much Professional Liability Insurance Does a Digital Health Company Actually Need?

The right professional liability limit for a digital health company is not the number the founder can stomach at renewal and is not the number a broker suggested without analysis. It is the number determined by three actual constraints: the largest contractual insurance requirement among the company’s customers, the revenue at risk in the most consequential engagements, and the realistic cost of defending a claim in the jurisdictions where the company operates. Companies that pick a limit by feel rather than by analysis are either carrying too little to meet contracts they have signed or paying for capacity they will not use.

Customer Contracts Set the Floor

The most reliable signal is the contracts the company has already signed. A health system master services agreement specifies a per-occurrence and aggregate limit for professional liability and technology errors and omissions, often in the low seven figures at the entry stage and rising as the engagement deepens. A payor agreement does the same and may name analytics E&O specifically. A government contract carries its own FAR-driven requirements, and an enterprise SaaS agreement with a large covered entity has its own data-protection and indemnification structure.

Read against this checklist, the floor for the company’s professional liability limit is the highest per-occurrence requirement on the highest-value contract currently in force, and the aggregate has to absorb the realistic possibility of more than one claim in a policy year. A program that meets each individual contract but cannot absorb two simultaneous claims at full limit is a program that meets the letter and not the substance, the same dynamic mapped in what insurance an enterprise contract requires for a digital health company.

Revenue at Risk Sets the Practical Question

The contract floor is the minimum; the practical question is what is at risk in a claim. A platform that touches care decisions for tens of thousands of users carries an exposure that scales with the user count and the consequence of a failure, not only with the customer’s contract requirement. The professional liability exposure for a clinical decision-support platform that influences treatment recommendations is structurally different from a scheduling platform that does not, even when the two carry similar customer-contract limits, the reliance-on-output mechanism detailed in what triggers a professional liability claim for a digital health app.

The practical sizing question is what claim a plaintiff might bring and what range a court might award. For a digital health company touching clinical decisions, that range can scale into the high seven or eight figures for a class action, the kind of exposure the company has to be able to absorb with policy limits, not with cash. The Tech E&O line carries an adjacent question, since the same incident can engage both lines and the limit on each has to be sized for the share each is likely to pay, the boundary explained in Tech E&O versus products liability for SaMD.

Defense Cost Is the Quiet Variable

Defense is the cost that erodes the limit before any indemnity. A claims-made professional liability policy can be written with defense inside the limit (defense costs reduce the policy’s available limit dollar for dollar) or defense outside the limit (defense costs are paid in addition to the policy limit). The two structures look similar on a certificate and price differently at claim. A defense-inside structure on a high-severity professional liability case can consume meaningful portions of the limit before any settlement, and a company that sized the program against an indemnity-only assumption has under-sized it for the defense reality.

For a digital health company operating across multiple states or in foreign jurisdictions, defense costs vary by venue, and the higher-cost venues are usually the higher-stake ones. A platform with material EU exposure also faces a different defense profile than a US-only platform, the dimension covered in whether a digital health platform needs insurance for international users.

Where Founders Get the Math Wrong

Three errors recur. The first is matching the limit a peer carries, which is a survey of decisions made under the same incomplete data. The second is sizing to historical claims experience, which is meaningful for a mature company and almost meaningless for a fast-growing one whose exposure has outrun its history. The third is treating the limit as fixed for the policy year rather than revisiting it when a major contract, a material user growth, a new clinical feature, or a new geography changes the inputs.

What to Do Now

Lay the company’s top five customer contracts next to the current professional liability and Tech E&O limits and confirm the program meets each one with room for a second concurrent claim. Pull the realistic defense and indemnity ranges for the kinds of claims the platform’s actual functions could generate, in the jurisdictions where the company operates. Confirm the defense structure on the policy (inside or outside the limit) and re-size accordingly if defense is inside. Revisit the limit when any of the inputs (contracts, user base, feature scope, geography) changes materially, not only at renewal.

The right number is the one the company can defend with this analysis if a claim arrives. A specialty review through Tower Street Insurance can size a digital health company’s professional liability and Tech E&O limits against the contracts in force, the platform’s actual functions, and the jurisdictions it operates in.
