Bottom line
- Pick MD Clarity if you're a physician group or MSO that suspects payers are underpaying contracts and wants sidecar analytics without ripping out your PM system.
- Pick Rivet if your practice or billing team needs patient estimates, underpayment recovery, and denial tools that plug into your current PM system.
MD Clarity
Underpayment detection and patient estimates for provider groups
- Founded
- 2010
- HQ
- Seattle, WA
- Stage
- Bootstrapped
- Raised
- n/a
What it does
- Line-item underpayment detection against contract terms
- Payer contract modeling and rate benchmarking
- Automated patient cost estimates and GFEs
- No Surprises Act compliance
- Denial tracking and categorization
- In-house underpayment recovery services
Where it's strong
- Does both detection and recovery: software surfaces variances and an in-house services team can chase the money, so you are not stitching two vendors together.
- Contract modeling plus estimates in one platform means the same rate engine powers payer accountability and patient transparency.
- Bootstrapped and profitable-minded, so no investor-driven pivots or forced upsells.
What buyers should weigh
- A smaller company (tens of employees), so implementation bandwidth and enterprise support depth are thinner than large RCM vendors.
- Value depends on loading accurate, current payer contracts; groups with messy or unmanaged contracts face real setup work.
- Aimed at physician groups and MSOs; large hospital systems on Epic may find native or enterprise tools a more common path.

Rivet
Estimates, underpayment recovery, and denial workflows
- Founded
- 2018
- HQ
- Salt Lake City, UT
- Stage
- Acquired by Zelis (January 2026)
- Raised
- $31.5M
What it does
- Upfront patient cost estimates and good faith estimates
- Payer contract modeling down to the TIN level
- Automated underpayment detection against contracted rates
- Denial and payment variance dashboards
- Worklists for recovery project management
Where it's strong
- Unusually broad integration surface for its size, with 30+ practice management and clearinghouse connections including Epic and athenahealth.
- It pairs front-end estimates with back-end underpayment recovery, so one contract dataset powers both.
- Zelis ownership brings the resources and payer network of a much larger payments company.
What buyers should weigh
- The January 2026 Zelis acquisition means roadmap, pricing, and support models could change; ask hard questions about product continuity.
- Zelis primarily serves 750+ payers, and some provider organizations will be uneasy having their underpayment data inside a payer-aligned vendor.
- Its history is strongest with physician groups and mid-size practices, less proven as an enterprise hospital platform.
