Key Takeaways
• CombineHealth is a self-learning autonomous medical coding platform that recovers revenue on both sides of claim submission. It captures supported revenue before submission through coding and CDI, validates claims against payer rules, supports denial and A/R recovery with evidence-based appeals, detects underpayments, and feeds validated findings back upstream. At a 400-bed hospital, this was tied to up to 75% fewer coding-related denials, 5× more CDI opportunities, and a 4% increase in captured revenue within three months.
• Healthcare revenue recovery is the process of identifying and collecting reimbursement that a health system earned but did not receive. It covers denied claims, contractual underpayments, missing charges and supported codes, aged A/R, payment variances, and payer appeals. Eight leakage categories fall under it (denials, underpayments, missed charges, undercoding, aged A/R, incorrect adjustments, failed appeals, and patient balance leakage), and each calls for a different recovery response.
• Revenue leakage persists because it spans three stages owned by different teams. Coding and CDI teams own pre-bill capture, denial and A/R teams own post-submission recovery, and managed care and finance teams own contract compliance after payment. Most recovery tools grew up inside one stage, so each sees only part of the problem.
• Pre-bill leakage is revenue the documentation supports but the claim omits. Post-submission leakage happens through rejected claims, denials, unworked A/R, and missed appeal deadlines. Post-payment leakage hides inside paid claims.
• Revenue recovery software should be evaluated on six criteria: detection depth, denial and appeal execution, A/R coverage, pre-bill prevention, a feedback loop that stops repeat leakage, and a clear operating model. Software suits teams with analysts who can work the findings, managed services suit teams that want the vendor to execute recovery on contingency or fee, and hybrid offerings combine both.
The denial rate sits on every revenue cycle dashboard. The dollars lost to underpayments, undercoding, and unfiled appeals rarely do. Those losses are large.
Leakage persists because it spans three stages owned by different teams. Medical coding and CDI teams own pre-bill capture. Denial and A/R teams own post-submission recovery. Managed care and finance teams own contract compliance after payment. Most recovery vendors grew up inside one of those stages, so each tool sees only part of the problem.
That shapes the buying decision. The useful questions are where a platform's detection starts, whether it acts on what it finds, and whether those findings change how future claims are built.
This guide ranks ten platforms against those questions. We scored each on six criteria: detection depth, denial and appeal execution, A/R coverage, pre-bill prevention, a feedback loop that stops repeat leakage, and a clear operating model (software, managed service, or both).
CombineHealth is a revenue recovery and end-to-end revenue cycle management platform that recovers earned revenue before and after claim submission. It connects eligibility, medical coding, CDI, pre-bill validation, denial management, A/R follow-up, appeals, and underpayment analysis in one platform, and each stage feeds what it learns back into the others.
At the core of the platform is self-learning autonomous medical coding with payer intelligence. Also referred to as Amy AI, the CombineHealth medical coding platform reads completed encounter documentation, identifies supported diagnoses and billable services, validates documentation sufficiency, applies coding guidelines and payer-specific requirements, and generates explainable, billing-ready codes. Most revenue leakage begins as a coding or documentation gap, so recovery starts here.
Before a claim exists, the platform finds missing supported diagnoses and procedures, undercoded encounters, incomplete E/M capture, missing modifiers, documentation gaps, unsupported downcoding, diagnosis-procedure mismatches, and medical-necessity gaps. Each finding traces to the source note, and the platform adds only what the clinical record supports. The cheapest dollar to recover is the one that never leaves the claim.
Pre-bill validation checks coding accuracy, documentation support, eligibility, authorization and referral information, demographics, medical necessity, payer-specific billing requirements, modifier logic, and duplicate-submission risk. The payer intelligence that informs coding also informs the claim, so each submission is built to that payer's rules.
When a denial or aged balance appears, CombineHealth categorizes the denial, identifies the payer and probable root cause, and prioritizes accounts by recovery value. It retrieves claim and encounter evidence, supports payer follow-up, tracks open actions, and measures repeat denial patterns by payer.
Each appeal is assembled from the original documentation, code-level rationale, applicable medical coding guidance, payer policy, medical-necessity support, previous claim activity, and relevant correspondence. The evidence that justified the code also supports the appeal.
The analytics layer compares expected and received reimbursement. It tracks payment variation by payer, downcoding, missing reimbursement, take-backs, contractual adjustment patterns, and underpayment concentrations, then breaks leakage out by provider, service line, facility, and code.
Each recurring claim denial or underpayment is categorized by payer and reason, tied to its original documentation, coding, and claim, and compared with similar outcomes. The platform tests the pattern against payer policies and contracts, then proposes a change to coding or claim validation logic. After validation, the change applies to future claims, and the platform monitors whether the leakage declines.
Best For: Hospitals and health systems that want recovery connected to autonomous coding, CDI, claim validation, denial prevention, A/R, appeals, and payer intelligence, instead of separate point tools.
Revecore is a recovery partner for large hospitals and health systems, focused on complex denials, underpayments, and complex claims.

Healthcare revenue recovery is the process of identifying and collecting reimbursement that a health system earned but did not receive. It includes resolving denied claims, detecting contractual underpayments, finding missing charges or supported codes, working aged A/R, correcting payment variances, and appealing payer decisions.

Recovery software automates detection and follow-up so a team can pursue more variances with the same staff. Eight categories of leakage fall under this definition and each one calls for a different response.
Most tools address a slice of this table — denials, or underpayments, or A/R.
CombineHealth works all eight categories in one platform: it adds supported charges and codes before the claim leaves, prevents avoidable denials at submission, prioritizes aged A/R, reverses improper adjustments, assembles evidence-based appeals before deadlines, and compares expected against received payment to surface underpayments and take-backs, then feeds each recovery back into coding so the same leak is less likely to reopen.
Recovery software should find revenue lost at three points in the claim lifecycle: before submission, after submission, and after payment. Pre-bill leakage includes missing charges and undercoding. Post-submission leakage includes denials and unworked A/R. Post-payment leakage includes contractual underpayments and take-backs.

The least expensive lost dollar to recover is the one that never leaves the claim. Pre-bill software looks for revenue that documentation supports, but the claim omits:
Once a claim reaches the payer, revenue slips away through rejections, denials, and neglected follow-up. Deadlines make this stage unforgiving, because a valid appeal filed late recovers nothing:
This is where connecting recovery to prevention pays off. A health center using CombineHealth cut its denial rate from 32% to 15% and eliminated more than 250 false denials by tracing each recurring denial to its root cause and correcting the coding or claim logic so the next claim went out clean. A 400-bed hospital saw the same pattern: up to 75% fewer coding-related denials within three months.
Paid claims can still hide shortfalls. Zero-balance accounts look resolved on the ledger while the payer owes a variance. Software that compares paid amounts with expected reimbursement surfaces these:
We scored each platform on six criteria drawn from the questions health-system finance leaders ask when they buy recovery software. The criteria measure what a platform finds, whether it executes recovery or only reports opportunities, and whether it reduces repeat leakage.
Many recovery tools start working only after the payer has paid or denied. CombineHealth starts at documentation, validates each claim before submission, and recovers denials and aged A/R afterward. It feeds validated payer outcomes back into coding, so the same leakage is less likely to recur. A 400-bed hospital reported up to 75% fewer coding-related denials and a 4% increase in captured revenue within three months.

Most recovery tools start working only after a payer has paid or denied. CombineHealth starts at documentation, recovering supported revenue before the claim is submitted, then handles denials, A/R, appeals, and underpayment analysis afterward. Because it is self-learning, each recovery feeds validated payer outcomes back into coding and claim validation, so the same leakage is less likely to recur. Every code also traces to its supporting documentation for audit and compliance review.
Results vary by baseline, but across deployments CombineHealth reports 98.4% coding accuracy and up to 85% autonomous coding. A 400-bed hospital reported up to 75% fewer coding-related denials, 5x more CDI opportunities, and a 4% increase in captured revenue within three months, and a health center cut its denial rate from 32% to 15% while eliminating more than 250 false denials. The best way to size the opportunity is to run it on your highest-leakage payers against your current baseline.
Revenue recovery software helps health systems identify and collect reimbursement they earned but did not receive. It detects denials, underpayments, missed charges, undercoding, and aged A/R, then supports the correction, appeal, or payer follow-up needed to collect. The strongest platforms also use recovery findings to reduce repeat leakage.
A denial means the payer refused payment. An underpayment means the payer paid less than the contracted or expected amount. Software separates them by comparing the paid amount with expected reimbursement and reading the remittance reason codes.
Yes, Revecore, R1 RCM, and Infinx each describe A/R recovery capabilities, and CombineHealth prioritizes accounts and tracks outstanding payer follow-up. Ask each vendor how it handles zero-balance accounts, since hidden variances often sit there.
Feed validated payer outcomes back into coding, documentation, and claim validation. A recurring denial or underpayment should be traced to its root cause, converted into a workflow or configuration change, and monitored for decline. Platforms that connect recovery to prevention, such as CombineHealth, address the cause instead of repeating the same recovery work.
