Brundage Group Takes Water Street Backing to Scale Hospital Revenue Tech

Brundage Group, a provider of clinical documentation and revenue integrity services to U.S. hospitals, has secured a growth investment from Water Street Healthcare Partners, the firms announced Monday. The deal — financial terms weren't disclosed — positions Brundage to expand its outsourced revenue cycle services at a moment when hospitals are desperate for margin relief.

The timing isn't accidental. U.S. hospitals are caught between flat or declining reimbursement rates and rising labor costs, pushing operating margins to multi-year lows. Revenue cycle management — the unglamorous backend work of ensuring every procedure gets coded, billed, and paid correctly — has become a survival priority. Brundage's pitch: let us handle the clinical documentation and charge capture so your staff can focus on patients instead of paperwork.

Founded in 1996 and based in Carmel, Indiana, Brundage has built a business around solving a specific, high-value problem: making sure hospitals capture every dollar they're owed. That means deploying certified coders and revenue integrity specialists — either on-site or remotely — to review clinical documentation, identify missing charges, and ensure compliance with ever-shifting payer rules. The company's client base includes both community hospitals and large health systems across the country.

Water Street, a Boston-based private equity firm focused exclusively on healthcare, sees the investment as a bet on structural demand. "Hospitals are under relentless financial pressure," the firm noted in its announcement, pointing to reimbursement headwinds and workforce shortages as catalysts driving outsourcing adoption. The firm's healthcare-only mandate means it's spent the past two decades watching revenue cycle vendors consolidate and scale — and it thinks Brundage is positioned to be a category winner.

The hospital revenue cycle has always been complex — a Rube Goldberg machine of clinical workflows, coding taxonomies, payer contracts, and compliance requirements. But the past few years have turned complexity into crisis.

First, reimbursement pressure. Medicare payment updates have lagged inflation for years, and commercial payers are increasingly adopting value-based contracts that shift financial risk onto providers. Hospitals are getting paid less per patient even as costs rise.

Second, staffing shortages. The pandemic accelerated attrition among clinical documentation specialists and medical coders — roles that require specialized training and certification. Hospitals can't hire fast enough to keep up with turnover, and salary expectations have spiked. Outsourcing becomes attractive when the alternative is leaving positions open for months.

Third, regulatory complexity keeps escalating. ICD-10 code sets expand annually. CMS payment rules change. Payer policies diverge. Staying compliant — and optimizing reimbursement within those rules — demands expertise that many hospitals simply don't have in-house at sufficient depth. A missed code or an underdocumented diagnosis isn't just a paperwork error; it's lost revenue that never comes back.

Brundage operates in two adjacent but distinct lanes: clinical documentation improvement (CDI) and revenue integrity. Both aim to maximize appropriate reimbursement, but they attack the problem from different angles.

CDI focuses on ensuring that clinical documentation — the notes physicians and nurses create during patient care — accurately reflects the severity and complexity of each case. If a doctor treats a patient for heart failure but doesn't document the specific type and stage, the hospital's reimbursement drops because the coded diagnosis doesn't capture the full clinical picture. Brundage's CDI specialists review charts in near-real-time, flagging gaps and working with clinicians to improve documentation before the claim gets submitted.

Revenue integrity, meanwhile, is about charge capture and billing accuracy. Did the hospital bill for every procedure performed? Are the charges coded correctly? Are denials being appealed effectively? Brundage's revenue integrity teams audit workflows, identify leakage points, and implement process fixes to ensure nothing slips through the cracks.

The barrier to entry here isn't technology — it's talent and domain expertise. You need people who understand both clinical workflows and payer rules, who can speak credibly to physicians, and who stay current on regulatory changes. Brundage has spent nearly three decades building that bench. Water Street's bet is that this human capital advantage — combined with growing outsourcing demand — creates a durable moat.

One differentiator: Brundage offers both on-site and remote staffing models. Some hospitals want consultants embedded in their facilities, working alongside clinical teams. Others prefer a fully remote model to reduce overhead. Brundage can flex between the two, or deliver a hybrid approach depending on client needs. That flexibility matters in a market where smaller community hospitals have different constraints than large urban health systems.

Water Street Healthcare Partners isn't a generalist private equity firm dabbling in healthcare. The firm manages over $4 billion in committed capital and invests exclusively in healthcare services, technology, and distribution businesses. Its portfolio includes everything from specialty pharmacy platforms to behavioral health providers to — relevant here — revenue cycle and health IT companies.

The firm's thesis in healthcare services tends to follow a pattern: find fragmented, high-value workflows that hospitals are increasingly willing to outsource, back a capable operator, then fund organic growth and M&A to build scale. Revenue cycle fits that template perfectly. The market is fragmented, the need is urgent, and consolidation is underway.

Water Street's involvement signals more than just capital. The firm brings a network of hospital system relationships, operational expertise from prior healthcare investments, and a track record of helping portfolio companies execute buy-and-build strategies. For Brundage, that likely means both organic expansion — adding headcount, entering new geographies, deepening existing client relationships — and potential acquisitions of smaller revenue cycle or CDI competitors.

"This partnership will enable us to accelerate growth, expand our service offerings, and continue delivering measurable value to our hospital and health system partners," Brundage Group's leadership said in the announcement. Translation: expect M&A and geographic expansion in the next 12-24 months.

The firm's existing portfolio includes companies like Enhance Health, a Medicare Advantage services platform, and Gateway Health Plan, a managed care organization — both adjacent to the revenue cycle ecosystem. That suggests Water Street sees value in building a connected set of healthcare services assets that can cross-sell or integrate over time.

The announcement describes the investment as a "partnership" and positions Water Street as a growth capital provider, which typically implies a minority stake rather than a full buyout. Brundage's founders and existing leadership appear to remain involved. That structure makes sense for a profitable, growing business that doesn't need a balance sheet restructuring — just fuel for expansion.

Growth equity deals in healthcare services typically carry lower leverage than traditional buyouts and emphasize organic growth and M&A over financial engineering. Water Street's capital will likely fund talent acquisition, geographic expansion, technology investments (more on that below), and tuck-in acquisitions of regional competitors.

Brundage isn't operating in a vacuum. The hospital revenue cycle outsourcing market has seen steady consolidation, with larger players acquiring regional vendors and rolling up fragmented capacity. The competitive landscape breaks into a few tiers.

At the top, you have the large, publicly traded RCM platforms — companies like R1 RCM (which has executed a multi-year buy-and-build strategy backed by TowerBrook Capital Partners before going public) and Ensemble Health Partners (formed through the merger of multiple regional RCM companies). These firms operate at massive scale, often taking over entire revenue cycle departments for large health systems under long-term contracts.

A tier below, you find specialized vendors focused on specific workflows — CDI, coding, denial management, patient access — rather than full end-to-end RCM outsourcing. Brundage operates primarily in this segment, though with ambitions to move upmarket. Companies like Acclara Health, nThrive, and Ciox Health compete here, each with slightly different service mixes and geographic footprints.

Then there's the long tail: hundreds of small, regional revenue cycle consultancies and staffing firms. Many are founder-owned, serve a handful of local hospitals, and lack the capital or talent infrastructure to scale nationally. This is the M&A target list for firms like Brundage post-investment.

One question hanging over the revenue cycle outsourcing market: how much of this gets automated away? AI-powered coding assistants, natural language processing for clinical documentation, and robotic process automation for billing workflows are all advancing quickly. If software can do what Brundage's human specialists currently do, the outsourcing model breaks.

The counterargument — and likely Water Street's view — is that technology augments rather than replaces. Automated coding tools can handle straightforward cases, but complex, high-value admissions still require human judgment. Revenue integrity isn't just data entry; it's process redesign, physician engagement, and payer negotiation. The winning model is probably hybrid: technology handles volume, humans handle exceptions and strategy.

Expect Brundage to accelerate technology investments post-deal — not to replace staff, but to make them more efficient and expand the TAM by serving smaller hospitals that couldn't previously afford on-site consultants.

For hospital CFOs and revenue cycle leaders, this deal is another data point in a clear trend: revenue cycle is moving from an internal function to an outsourced partnership. The question isn't whether to outsource anymore — it's which vendor to pick and which workflows to hand off first.

Brundage's value proposition — deeply embedded expertise, flexible staffing models, measurable ROI — resonates in a margin-constrained environment. Hospitals don't have the luxury of waiting six months to hire and train a CDI specialist when every quarter of underdocumentation costs real money. Outsourcing gets expertise in place faster and shifts financial risk to the vendor (most RCM contracts include performance guarantees tied to revenue lift or denial rate reduction).

But outsourcing introduces its own risks. Hospitals cede control over a critical function. Vendor performance issues can directly impact cash flow. And long-term contracts can lock in unfavorable economics if the market shifts. The most successful partnerships tend to be highly collaborative, with clear performance metrics, regular reviews, and mutual accountability — not just a vendor relationship.

Brundage's track record — nearly 30 years in business, long-term client relationships, measurable outcomes — suggests it's navigated these dynamics successfully. Water Street's backing should accelerate product development and geographic reach, but the core model remains human-capital-intensive and relationship-driven. That's either a strength (hard to disrupt) or a constraint (hard to scale) depending on execution.

Zoom out, and the Brundage-Water Street deal fits into a broader pattern: private equity's sustained interest in healthcare services businesses that ride structural tailwinds. Revenue cycle outsourcing checks every box PE firms look for — recurring revenue, defensible expertise, fragmented competition, and a customer base (hospitals) that's not going away.

Healthcare services M&A volume has remained resilient even as broader dealmaking slowed in 2023-2024. Investors are hunting for assets insulated from economic cycles, and healthcare — especially non-discretionary services tied to hospital operations — fits that profile. Revenue cycle is particularly attractive because it's a cost center that can be turned into a profit center through better execution. Hospitals will always need it, and they're increasingly willing to pay for outside help.

Water Street's investment likely values Brundage at a meaningful multiple of EBITDA, though neither party disclosed terms. Comparable transactions in the RCM and healthcare IT services space have traded in the 10-15x range for high-growth, profitable platforms. If Brundage can demonstrate consistent double-digit organic growth and execute a buy-and-build strategy, an exit in the next 4-6 years — either to a strategic buyer or a larger PE firm — is plausible.

Strategic acquirers to watch: the large publicly traded RCM platforms (R1, Ensemble) that have been serial consolidators, as well as healthcare IT giants like Optum and Change Healthcare (now part of UnitedHealth Group) that are building vertically integrated revenue cycle and care delivery platforms. A scaled Brundage, with national reach and deep client relationships, becomes an attractive bolt-on for any of them.

In the near term, expect Brundage to accelerate hiring — both revenue-generating roles (CDI specialists, coders) and G&A infrastructure to support growth. Geographic expansion will likely target underserved markets where community hospitals lack access to sophisticated revenue cycle expertise.

M&A seems inevitable. Water Street didn't invest to sit still. Look for tuck-in acquisitions of regional CDI or revenue integrity firms that expand Brundage's footprint or add complementary capabilities. The firm may also consider technology acquisitions — buying a coding automation tool or documentation workflow platform to integrate into its service delivery model.

Longer term, the question is whether Brundage expands into full end-to-end revenue cycle management, competing with the R1s and Ensembles of the world, or stays focused on its CDI and revenue integrity niche where it has deep expertise. Both paths are viable. The former offers a bigger TAM but requires significant capital and operational complexity. The latter is more defensible but may limit exit multiples.

For now, Brundage has the capital, the partner, and the market tailwinds to grow aggressively. Whether it becomes a national platform or a best-in-class regional player depends on execution over the next few years. Either way, hospitals desperate for margin relief have one more well-funded option. And Water Street has another bet on healthcare's messy, essential plumbing — the kind that doesn't make headlines but makes money.
