Should you build or buy Coordination of Benefits & Subrogation Recovery Platform?
Coordination of Benefits & Subrogation Recovery Platform software manages the identification of other-insurance liability for health plan claims and pursues recovery from third parties when another payer is primary. It handles COB matching against cross-payer eligibility data and administers the legal and workflow processes required to recover subrogation dollars from auto, workers' comp, and liability insurers.
The build-vs-buy decision for Coordination of Benefits & Subrogation Recovery turns on how replaceable the cross-payer eligibility data network is and how much of the recovery workflow is driven by legal process infrastructure rather than software logic; the specifics of data scale and recovery volume decide it.
Build it, buy it, or bridge?
When building makes sense
The build case for COB and subrogation recovery is narrow, and it only makes economic sense for very large payers. The core asset in this category is the cross-payer eligibility data network. Identifying other-insurance liability at scale requires data relationships with other payers that take years and significant negotiating leverage to assemble. No internal team replicates that from scratch. The part of the function where building pays off is the analytics layer on top of vendor-managed recovery workflows: tracking edit resolution patterns, monitoring recovery rates by claim type, and identifying upstream data quality issues that are costing you recovery dollars. A very large plan with direct data agreements and an in-house legal team pursuing subrogation could control more of the process. But that scenario requires a claims book large enough to justify the legal infrastructure and data engineering investment, which applies to a small fraction of payers.
When buying makes sense
Buying makes sense for almost every health plan in this category because the value lives in the data, not the software. Vendors like The Rawlings Group, Cotiviti, and Equian/Optum hold cross-payer eligibility networks assembled over many years of multi-payer data agreements. That network is what makes matching accurate and recovery defensible. Contingency-based pricing aligns vendor incentives directly with recoveries, so the cost model is inherently tied to what you actually get back. The legal process infrastructure for subrogation, from liability pursuit through remittance, is also largely vendor-maintained. CMS and NAIC COB rules are standardized across payers, which means the logic itself isn't proprietary. This is cost containment hygiene, not a competitive differentiator, and the vendor structure is specifically built to serve that function efficiently.
The desk read
Coordination of benefits and subrogation recovery are compliance-driven cost containment functions. The COB rules themselves follow CMS and NAIC guidelines that apply uniformly across payers, and the subrogation workflow, identify third-party liability, pursue recovery, remit results, is a legal process as much as a software problem. Vendors like The Rawlings Group (Machinify), Cotiviti, and HMS (Gainwell) operate on contingency models, which means their incentives are aligned with actual recovery outcomes rather than license fees.
The core asset these vendors hold is a cross-payer eligibility data network. Matching claims against other-insurance records at scale requires data relationships that no internal team can replicate without years of multi-payer data agreements. AI can improve matching precision within a dataset, but it can't substitute for the proprietary data graph itself. Buying makes sense in this category not because the workflow is technically complex, but because the data network is the product. The build case is narrow: it applies primarily to very large payers with sufficient claims volume to negotiate direct data relationships and the legal infrastructure to pursue subrogation internally.
Frequently asked
What is Coordination of Benefits & Subrogation Recovery Platform software?
Coordination of Benefits & Subrogation Recovery Platform software manages the identification of other-insurance liability for health plan claims and pursues recovery from third parties when another payer is primary. It handles COB matching against cross-payer eligibility data and administers the legal and workflow processes required to recover subrogation dollars from auto, workers' comp, and liability insurers.
When does building Coordination of Benefits & Subrogation Recovery Platform make sense?
Building is realistic only for very large payers that have already established direct cross-payer data agreements and maintain in-house legal infrastructure for subrogation pursuit. The data network is the product; internal software alone doesn't replicate it.
When does buying Coordination of Benefits & Subrogation Recovery Platform make sense?
Buying makes sense for most health plans because vendor data networks and contingency-based pricing are structurally aligned with recovery outcomes, and replicating the cross-payer eligibility graph internally is cost-prohibitive for all but the largest payers.
What are the main Coordination of Benefits & Subrogation Recovery Platform vendors?
Representative vendors include The Rawlings Group (Machinify), Conduent COB Services, Cotiviti, Equian / Optum (subrogation). B4 Pro scores the full set.
How does contingency pricing work for subrogation recovery vendors?
Most subrogation vendors charge a percentage of dollars recovered rather than a flat license fee, which means their revenue is directly tied to how much they recover on your behalf. This aligns incentives and reduces upfront risk for the health plan.
