Should you build or buy Payer Payment Integrity Platform (Pre & Post-Pay)?

Payer Payment Integrity Platform software detects billing errors, duplicate claims, coding inconsistencies, and fraudulent billing patterns before claims are paid (pre-pay editing) and after payment has occurred (post-pay mining and recovery). It applies clinical coding rules, DRG validation, unbundling logic, and machine learning models to reduce improper payments across a health plan's claims book.

Purchase the content and the recovery muscle; own the data and the models. The question to put to a renewal is which half you are actually paying for. If the fee is a blended percentage covering edit content, clinical review, benchmarks and recovery alike, unbundle it — plans that have built their own claims data layer and anomaly models find the vendors remaining value concentrated in policy maintenance, chart review capacity and cross-payer pattern discovery, all of which price differently than a share of every dollar recovered. Insourcing detection without insourcing the edit library is the common and correct middle.

Cost shape
Estimate implementation, retained services, integration, validation, and ongoing operations for the defined scope.
Contingency pricing aligns incentives but compounds cost at high claims volumes
Internal ML for own-data patterns; vendor for cross-payer anomaly detection and complex edits
Time to value
Depends on the defined scope, data readiness, integrations, and production acceptance tests.
Out-of-box editing rules and live models available quickly
Vendor edits running quickly; internal models trained in parallel on own-population data
Differentiation captured
None from payment integrity itself; cost savings go to the bottom line but don't create market position
Vendor's cross-payer data finds patterns no single plan's book reveals
Internal models tuned to plan-specific billing patterns add savings above vendor baseline
AI feasibility today
The buyable core extends beyond a cross-payer dataset. Mature claims ML does not establish a complete payment-integrity replacement.
Vendors hold cross-payer data advantage; independent builds lack that signal
Build claims analysis, internal policy oversight, or targeted review; retain services for edit libraries, code-set content, clinical validation, policy maintenance, and recovery operations.
Who it fits
Teams with a defined need for claims analysis, internal policy oversight, or targeted review and capacity to operate it.
Smaller payers and plans without data science capacity to retrain models against shifting fraud patterns
Mid-to-large plans wanting own-data ML advantage without abandoning cross-payer edit coverage

When building makes sense

Consider an internal build for claims analysis, internal policy oversight, or targeted review. The buyable core extends beyond a cross-payer dataset. Mature claims ML does not establish a complete payment-integrity replacement.

When buying makes sense

Buying earns its keep when you need edit libraries, code-set content, clinical validation, policy maintenance, and recovery operations. Compare the vendor’s coverage with the staff, integrations, and controls an internal option would need. Custom extensions can remain useful without replacing the core.
