E00-E89

Endocrine, nutritional and metabolic diseases

This chapter covers ICD-10-CM codes in the range E00-E89 for endocrine, nutritional and metabolic diseases. Includes disorders of the endocrine glands, nutritional deficiencies, metabolic disorders, and diabetes mellitus.

72 codes

Chapter Overview

Key Statistics

  • Contains 10 categories and 72 total codes
  • Includes 60 billable codes and 12 non-billable codes
  • Chapter range: E00-E89

Clinical Relevance

Used for coding endocrine disorders (diabetes, thyroid conditions), nutritional deficiencies, and metabolic diseases. Essential for endocrinology, internal medicine, and primary care documentation.

Documentation Requirements

Requires specific hormone levels, laboratory values, nutritional status assessment, and manifestation documentation. Type 1 vs Type 2 diabetes distinction is critical.

Special Considerations

Includes diabetes mellitus coding with mandatory use of additional codes for complications and manifestations.

Chapter-Specific Coding Guidelines

General Guidelines for Endocrine, nutritional and metabolic diseases:

  1. Follow standard ICD-10-CM coding principles for endocrine, nutritional and metabolic diseases
  2. Document the most specific diagnosis supported by the medical record
  3. Use additional codes for manifestations, complications, or associated conditions
  4. Ensure proper sequencing based on the reason for the encounter

Documentation Requirements:

  • Specific condition or disease process
  • Acute versus chronic status when applicable
  • Severity or stage when documented
  • Associated symptoms or complications
  • Treatment response and current status

Sequencing Rules:

  • Principal diagnosis should reflect the main reason for the encounter
  • Sequence complications according to treatment focus
  • Use appropriate combination codes when available
  • Follow chapter-specific sequencing guidelines

When to Use:

  • For conditions classified in the E00-E89 range
  • When the condition is the primary focus of care
  • During active treatment or monitoring
  • For documented complications of the condition

When NOT to Use:

  • For personal history without current manifestations
  • During screening encounters without findings
  • For conditions better classified elsewhere
  • When condition is ruled out or suspected only

Special Considerations:

  • Review chapter-specific coding guidelines
  • Consider combination codes before multiple codes
  • Document functional impact when relevant
  • Use external cause codes when applicable

Version Updates

The 2025 ICD-10-CM updates include refinements to endocrine, nutritional and metabolic diseases coding for improved specificity and clinical relevance.

Recent Updates:

Enhanced Endocrine, nutritional and metabolic diseases Specificity

Updated codes within E00-E89 for improved clinical documentation

Impact: Better alignment with clinical practice and quality reporting

2025-01-01

Implementation Guidance:

  • Review all endocrine, nutritional and metabolic diseases coding practices
  • Update documentation templates as needed
  • Train coding staff on any new requirements
  • Implement quality checks for accuracy

Upcoming Changes:

  • Potential enhancements to endocrine, nutritional and metabolic diseases codes in future updates
  • Continued alignment with clinical practice evolution
