What You Can Do
You can audit medical records against DRG assignment logic to uncover documented but uncoded secondary diagnoses, validate HCC capture, detect sequencing errors that affect DRG weight, and identify compliance risks before claim submission. This skill helps you maximize appropriate reimbursement by ensuring all clinically supported, properly documented conditions are captured and sequenced correctly—distinguishing between legitimate optimization and prohibited upcoding.
Features
Scans clinical documentation to surface comorbidities and complications that are documented but missing from the current code set
Cross-references documented conditions against Hierarchical Condition Category hierarchies to ensure higher-value codes are captured when clinically justified
Reviews code order and principal diagnosis assignment to confirm alignment with DRG logic and identify sequencing errors that artificially lower case weight
Flags missing documentation, contradictions, or coding choices that could trigger audit risk or denial
Analyzes whether the assigned DRG weight reflects actual clinical acuity based on documented conditions and procedures
Evaluates charts for completeness and physician-coder alignment before internal or external audit
Identifies missing or miscoded diagnoses that may explain payment denials and resubmission opportunities
Example Output
Input: Discharge summary showing Type 2 diabetes, hypertension, COPD, acute exacerbation of asthma, and congestive heart failure—but current codes omit the CHF.
Output:
- ✓ Secondary diagnosis found: Congestive heart failure (documented in clinical narrative, not coded)
- ✓ HCC opportunity: COPD with acute exacerbation maps to HCC 111; verify if documented as acute exacerbation to capture higher weight
- ✓ Sequencing check: Acute exacerbation of asthma sequenced as principal diagnosis—confirm this is the admission reason or if another condition should be principal
- ✓ Compliance note: No contradictions detected; documentation supports all identified conditions
- ✓ Recommended action: Add CHF code; confirm COPD exacerbation documentation; validate principal diagnosis assignment
Another example: Post-operative sepsis case with missing documentation of the site of infection.
Output:
- ⚠ Compliance gap: Sepsis documented but infection source not specified; request clarification from physician
- ✓ HCC validation: If urinary tract source confirmed, qualifies for higher HCC assignment
- ✓ Audit risk: Sepsis without documented source may trigger external audit; requires physician query
What's Included
- SKILL.md instruction file with DRG optimization guidelines and compliance boundaries:
- Documentation Checklist: audit form for secondary diagnoses, HCC opportunities, and sequencing validation
- DRG Sequencing Reference: quick-lookup guide for principal vs. secondary diagnosis rules and common sequencing errors
- HCC Mapping Worksheet: template for cross-referencing documented conditions against HCC hierarchies
- Compliance Red Flags Framework: checklist of audit-risk scenarios and how to resolve them
Who It's For
- Medical coders and coding auditors — optimize DRG assignments and prepare charts for internal/external audit
- Revenue cycle managers — identify coding gaps and compliance risks across case portfolios
- Clinical documentation improvement specialists — flag missing documentation and drive physician query workflows
- Health information management (HIM) directors — train coders on optimization principles and monitor compliance
- Coding compliance officers — detect coding patterns that may trigger audit risk and validate coder adherence to guidelines
Best For
- Admission/discharge summary review — surface undercoded secondary diagnoses and sequencing errors before claim submission
- High-dollar case analysis — ensure complex cases reflect documented acuity and capture all clinically supported HCC conditions
- Denied claim investigation — identify missing or miscoded diagnoses contributing to payment denials
- Coder training and validation — teach optimization principles and validate coder decisions against DRG logic
- Audit preparation — audit charts proactively to identify compliance gaps and reduce external audit risk

Analyze outpatient authorization requests against clinical evidence, payer guidelines, and regulatory standards to generate clear approval or denial recommendations with documented medical necessity justification. The skill transforms scattered clinical notes, procedure codes, insurance guidelines, and patient history into structured determinations that withstand peer-to-peer reviews, appeals, and regulatory audits while reducing decision time from hours to minutes.

You can conduct comprehensive pre-submission compliance audits of federal grant applications, budgets, and supporting documentation. Claude systematically validates alignment with OMB Uniform Guidance, agency-specific regulations, allowable cost policies, indirect cost structures, and institutional compliance standards. This identifies red flags—unallowable costs, cost-sharing mismatches, salary cap violations, F&A allocation errors, and subaward pass-through issues—before they reach federal reviewers, reducing submission delays and audit risk.
