Claim Denial Root Cause Analysis

Overview

Systematically analyze healthcare claim denials by decoding CARC (Claim Adjustment Reason Codes) and RARC (Remittance Advice Remark Codes), mapping to root causes across clinical documentation, coding, eligibility, authorization, and billing processes. This skill supports denial management teams in understanding why claims are denied, identifying systemic patterns, and implementing targeted corrective actions to improve clean claim rates and reduce revenue leakage.

When to Use

• Investigating individual claim denials for appeal preparation
• Analyzing denial trends across payers, departments, or service lines
• Identifying systemic root causes driving denial volumes
• Building denial prevention workflows and front-end edits
• Benchmarking denial rates against industry standards
• Preparing denial management performance reports
