R97.0

Elevated carcinoembryonic antigen [CEA]

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R97.0 is a billable code used to indicate a diagnosis of elevated carcinoembryonic antigen [cea].

Key Diagnostic Point:

Elevated carcinoembryonic antigen (CEA) is a laboratory finding often associated with various malignancies, particularly colorectal cancer. CEA is a glycoprotein involved in cell adhesion and is typically produced in fetal tissues. In adults, elevated levels can indicate the presence of certain cancers, but they may also be elevated in benign conditions such as inflammatory diseases, liver disease, and smoking. The clinical significance of elevated CEA levels lies in their use as a tumor marker for monitoring treatment response and disease recurrence in patients with known malignancies. However, it is important to note that CEA is not specific to cancer and should not be used as a standalone diagnostic tool. A comprehensive clinical evaluation, including patient history, physical examination, and additional diagnostic tests, is essential to interpret elevated CEA levels accurately.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Non-specificity of CEA as a tumor marker
  • Potential for elevated levels in benign conditions
  • Need for correlation with clinical findings
  • Variability in normal CEA levels based on smoking status

Audit Risk Factors

  • Inadequate documentation of clinical rationale for testing
  • Failure to correlate CEA levels with patient history
  • Misinterpretation of elevated CEA as definitive for cancer diagnosis
  • Lack of follow-up documentation for monitoring purposes

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Document the patient's history, physical examination findings, and any relevant imaging or lab results that support the need for CEA testing.

Common Clinical Scenarios

Patients with a history of colorectal cancer undergoing surveillance for recurrence.

Billing Considerations

Ensure that the reason for testing is clearly documented, especially if CEA is elevated in the absence of malignancy.

Emergency Medicine

Documentation Requirements

Document acute symptoms, lab results, and any immediate interventions taken based on elevated CEA levels.

Common Clinical Scenarios

Patients presenting with abdominal pain and elevated CEA levels, requiring urgent evaluation.

Billing Considerations

Consider the need for rapid assessment of potential malignancy versus benign causes of elevated CEA.

Coding Guidelines

Inclusion Criteria

Use R97.0 When
  • Follow official ICD
  • CM guidelines for coding abnormal lab findings, ensuring that the clinical context is documented
  • Use R97
  • 0 when CEA is elevated without a more specific diagnosis

Exclusion Criteria

Do NOT use R97.0 When
No specific exclusions found.

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of abnormal lab findings, including elevated CEA, which helps in better tracking and management of patients with malignancies.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of abnormal lab findings, including elevated CEA, which helps in better tracking and management of patients with malignancies.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of abnormal lab findings, including elevated CEA, which helps in better tracking and management of patients with malignancies.

Frequently Asked Questions

What does an elevated CEA level indicate?

An elevated CEA level can indicate the presence of certain cancers, particularly colorectal cancer, but it can also be elevated in benign conditions such as liver disease and smoking.

Is CEA used for cancer screening?

CEA is not recommended for general cancer screening; it is primarily used for monitoring treatment response and detecting recurrence in patients with a history of cancer.
