Complete code families applicable to Cost-Effectiveness Analysis

R97-R99Primary Range

Abnormal findings on examination of blood, without diagnosis

Includes codes for abnormal tumor markers like CEA.

Neoplasms

Used for coding underlying malignancies associated with elevated CEA.

Key Information: ICD-10 code for elevated CEA

Essential facts and insights about Cost-Effectiveness Analysis

The ICD-10 code for elevated carcinoembryonic antigen (CEA) is R97.0, used when CEA levels are elevated with clinical context.

Primary ICD-10-CM Code for cost-effectiveness analysis

Elevated carcinoembryonic antigen [CEA]
Billable Code

Decision Criteria

clinical Criteria

  • Elevated CEA levels with supporting clinical findings.

Applicable To

  • Elevated CEA level

Excludes

  • Normal CEA level

Clinical Validation Requirements

  • CEA >5 ng/mL in non-smokers
  • CEA >10 ng/mL in smokers

Code-Specific Risks

  • Incorrectly coding without specifying the CEA level.

Coding Notes

  • Ensure CEA level and clinical context are documented.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Malignant neoplasm of cecum

C18.0
Use when elevated CEA is due to colon cancer.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Other specified abnormal findings of blood chemistry

R79.89
Use when other blood markers are abnormal but CEA is normal.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Cost-Effectiveness Analysis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R97.0.

Impact

Clinical: Inaccurate clinical assessment., Regulatory: Non-compliance with documentation standards., Financial: Potential revenue loss due to incorrect coding.

Mitigation Strategy

Use templates to ensure complete documentation., Educate staff on documentation requirements.

Impact

Reimbursement: May lead to incorrect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Poor data quality and inaccurate clinical records.

Mitigation Strategy

Document the exact CEA level and clinical context.

Impact

Incomplete documentation of CEA levels.

Mitigation Strategy

Implement mandatory fields in EHR for CEA documentation.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Frequently Asked Questions

Common questions about ICD-10 coding for Cost-Effectiveness Analysis, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Cost-Effectiveness Analysis

Use these documentation templates to ensure complete and accurate documentation for Cost-Effectiveness Analysis. These templates include all required elements for proper coding and billing.

Oncology Follow-up

Specialty: Oncology

Required Elements

  • CEA level
  • Test date
  • Clinical context

Example Documentation

CEA level 15 ng/mL (ref: <5) on 03/27/25 serum test. Monitoring for recurrence post-colectomy for C18.0.

Examples: Poor vs. Good Documentation

Poor Documentation Example
CEA high, continue monitoring.
Good Documentation Example
CEA elevated to 28 ng/mL (3/27/25), correlating with 1.8 cm liver metastasis on MRI. Managing as recurrence of C18.0.
Explanation
The good example provides specific CEA levels and clinical context, improving clarity and compliance.
