What umbrella or excess limits do sponsor MSAs and hospital contracts require?

Insurance schedules in sponsor MSAs, GPO supplier agreements, and hospital purchase contracts almost never say "carry an umbrella." They state a required total limit - for example, "$10,000,000 per occurrence and in the aggregate, combined single limit" - and leave it to the operator to build to that total however the program is structured. In practice that means a primary general liability and products policy plus an umbrella and, if needed, excess layers.

The requirement is usually expressed against general liability and products and completed operations; some schedules also separately require auto and employers liability minimums, which the umbrella extends as well.

Mid-market CDMO or CRO on standard sponsor work: $5M-$10M total is the common requirement. 503B outsourcing facility supplying hospitals: $10M-$25M, driven by hospital purchase contracts and batch-level severity. Medical device manufacturer on GPO and hospital contracts: $10M-$25M for higher-risk implantables, less for lower-risk diagnostics. Oncology, sterile injectable, biologics, and controlled-substance manufacturing push the upper end across segments.

Operators serving multiple sponsors or hospitals should build to the highest single requirement on file - the program has to satisfy the toughest contract, not the average one.

A frequently missed point: when a sponsor or hospital requires additional insured status and primary, non-contributory wording, those requirements must extend through the umbrella and excess layers, not just the primary. If the sponsor is an additional insured on the $1M/$2M primary but the umbrella does not also extend additional insured status, the sponsor's protection effectively caps at the primary limit, defeating the purpose of requiring a higher total.

A correctly built tower extends additional insured and primary/non-contributory status consistently from the primary through the top of the umbrella and excess stack.

On the ACORD 25 certificate, the umbrella and excess limits appear in the umbrella/excess section, and the schedule of underlying confirms which primary policies the tower sits over. Vendor credentialing platforms - Symplr, Reptrax, Vendormate - check the total limit and the additional insured and notice-of-cancellation status against the contract schedule line by line.

The common credentialing failure is a certificate that shows the right primary limits but an umbrella that either falls short of the contract total or does not extend the required additional insured and primary wording. Having the broker issue a sample certificate against the actual contract schedule before binding surfaces these gaps early.
