Preventing Last-Minute Coverage Issues Across 1,200 Cardiovascular Procedures
A hospital-affiliated cardiovascular surgery group in North Carolina was experiencing recurring coverage issues before CABG, valve, and aortic procedures. Eligibility was often confirmed, but inpatient benefits, authorization details, secondary coverage, and financial clearance requirements were not consistently validated.
These gaps caused repeated payer calls, late authorization corrections, scheduling disruptions, and avoidable eligibility-related denials.
During a 100-day engagement, MBW RCM reviewed approximately 1,200 cardiovascular procedures and implemented a procedure-specific Eligibility & Benefits Verification workflow.

Challenges We Identified
Our assessment identified the following revenue cycle challenges impacting pre-surgical financial clearance and reimbursement.
➤ Incomplete Inpatient Benefit Validation
Eligibility verification confirmed active coverage but did not consistently validate inpatient benefits, deductibles, coinsurance, network status, or coverage limits for CABG, valve replacement, and other complex cardiac procedures.
➤ Authorization Did Not Match the Final Surgical Plan
Authorizations were approved for the initial procedure but were not updated when additional bypass grafts, valve procedures, or aortic repairs were added, resulting in CPT mismatches.
➤ Inconsistent Inpatient Admission Validation
The approved surgeon, facility, admission status, authorization dates, and length of stay were not consistently verified before surgery, increasing reimbursement risk.
➤ Medicare Secondary Payer and COB Verification Gaps
Medicare Secondary Payer (MSP) status and coordination of benefits were not consistently validated for patients with secondary or supplemental coverage.
➤ Fragmented Financial Clearance Workflow
Eligibility, authorization, scheduling, and patient access teams lacked a centralized financial clearance process, limiting visibility into unresolved payer requirements before surgery.
Our Approach
We strengthened the cardiovascular surgery Eligibility & Benefits Verification workflow to improve pre-surgical financial clearance and reduce reimbursement risk.
Our team standardized benefit validation, authorization reconciliation, admission verification, Medicare Secondary Payer (MSP) review, and coordination-of-benefits checks. Cases with changes to procedures, providers, facilities, surgery dates, or insurance coverage were re-verified before surgery.
Root Cause Analysis & Solutions
| Problem | Solution Implemented |
|---|---|
| Inpatient benefits were not consistently validated. | Our team standardized benefit verification 3–5 business days before surgery. |
| Authorizations did not match the final surgical plan. | Authorization reviews were reconciled with the final CPT codes within 24 hours of surgical plan changes. |
| Admission details were inconsistently verified. | Admission validation included the rendering surgeon, facility, admission status, and authorization dates 48 hours before surgery. |
| MSP and coordination-of-benefits reviews were incomplete. | We established a standardized MSP and coordination-of-benefits review before financial clearance. |
| Financial clearance activities were fragmented. | A centralized financial clearance workflow unified eligibility, authorization, scheduling, and patient access teams. |
Results:
98.6% verification accuracy through standardized benefit validation.
41% less authorization rework by matching approvals with final CPT codes.
94.7% of cases were financially cleared before surgery.
36% fewer eligibility-related denials through consistent MSP and COB verification.
Scheduling delays decreased by 29%.
A centralized workflow improved pre-service efficiency by 22%.
Successful cardiovascular surgery billing begins long before a claim is submitted. Strengthening eligibility verification, authorization accuracy, and financial clearance helped prevent last-minute coverage issues that could delay reimbursement for high-value cardiac procedures.
Across 1,200 cardiovascular procedures, our Eligibility & Benefits Verification workflow improved front-end revenue cycle performance, reduced payer-related disruptions, and created a stronger foundation for accurate cardiovascular surgery billing and faster reimbursement.
