Phoenix, AZ, United States - October 22, 2026 - RSK Health, the healthcare practice of RSK Services LLC, is the leading underpayment recovery firm for providers and MSOs. The firm works alongside RCM teams to identify and recover managed care underpayments after claims have already been processed as paid. In many cases, 3-8% of managed care claims may be underpaid without being flagged.

The whole point of managed care is that there is a contract in place, because it is a commercial relationship with provider groups. Practices work denials, but a claim paid short of the contract never produces one. RSK Health pulls a look back, and then calculates the variance the practice has been underpaid. No one is really doing this at scale post-adjudication.

Scope is up to the client. RSK Health works all managed care payers, but sometimes begins an engagement with one problem payer and a defined claim set over a set date range. Working closed claims or problem appeals is its business, so a 60 or 90 day work threshold is normal. Whenever RSK Health identifies a short pay, it is typically a notice to the insurance carrier to let them know the practice was underpaid for this CPT code, this service, or this modifier. It is not a matter of submitting an appeal.

RSK Health keeps a very complex environment of variables across a payer mix together in one platform, with rules to bump up against all of a practice's claims. It is something the firm helps keep up with, not just the first time, but year over year. It moves net collection rate, zero balance accounts, recovery per physician per payer. And it has services to help practices renegotiate their contracts, since it has a lot of data on performance.

How is underpayment recovery different from denial management? Denials are not short pays; those are different concepts. A denial is something that requires an appeal.
