Range Overview

high priority

The ICD-10 code range E65-E68 pertains to overweight, obesity, and other hyperalimentation. These codes are used to document conditions related to excessive food intake and its consequences. This range includes codes for overweight, obesity due to excess calories, morbid (severe) obesity, and other hyperalimentation.

Key Usage Points:

  • E65 is used for 'Localised adiposity', which refers to localized fat deposits.
  • E66 codes are used for different types of obesity, including due to excess calories, drug-induced, due to alcohol, and other obesity.
  • E67 codes are used for 'Other hyperalimentation', which includes conditions like overeating or polyphagia.
  • E68 is a code for 'Sequelae of hyperalimentation', used for conditions that are late effects of overeating.

Coding Guidelines

When to Use:

  • When a patient is diagnosed with obesity due to excess calories, use E66.0.
  • For a patient with drug-induced obesity, use E66.1.
  • If a patient is diagnosed with morbid (severe) obesity, use E66.2.
  • When a patient is diagnosed with obesity due to alcohol, use E66.8.

When NOT to Use:

  • Do not use E66 codes for patients with eating disorders like anorexia or bulimia.
  • Avoid E67 codes for patients with malnutrition or undernutrition.
  • Do not use E68 for patients without a history of hyperalimentation.
  • Avoid E65 for generalized obesity or overweight.

Code Exclusions

Always verify the exclusions with the patient's clinical documentation.

Documentation Requirements

Proper documentation for E65-E68 codes should include the type of condition, its cause, and any associated complications or comorbidities. The patient's body mass index (BMI) should also be documented.

Clinical Information:

  • Type of condition (overweight, obesity, etc.)
  • Cause of the condition (excess calories, drug-induced, etc.)
  • Associated complications or comorbidities
  • Patient's BMI

Supporting Evidence:

  • Physician's notes
  • Laboratory test results
  • Imaging reports
  • Nutritional assessment
Good Documentation Example:

Patient diagnosed with morbid obesity due to excess calories, with a BMI of 40.5. The patient also has type 2 diabetes.

Poor Documentation Example:

Patient is overweight.

Common Documentation Errors:

  • Not specifying the cause of the condition
  • Not documenting the patient's BMI
  • Not including associated complications or comorbidities

Coding Complexity

Medium
Complexity Rating

The complexity of these codes is medium due to the need to accurately document the cause of the condition, the patient's BMI, and any associated complications or comorbidities. It also requires differentiating between different types of obesity.

Key Factors:
  • Determining the cause of the condition
  • Documenting the patient's BMI
  • Identifying any associated complications or comorbidities
  • Differentiating between different types of obesity

Specialty Focus

These codes are commonly used in primary care, endocrinology, and bariatric surgery.

Primary Specialties:
Primary Care
40%
Endocrinology

Clinical Scenarios:
  • A patient with obesity due to excess calories presenting with hypertension.
  • A patient with drug-induced obesity due to corticosteroid therapy.
  • A patient with morbid obesity undergoing bariatric surgery.
  • A patient with obesity due to alcohol presenting with liver disease.

      Frequently Asked Questions

      Can E65-E68 codes be used for patients with eating disorders?

      No, these codes should not be used for patients with eating disorders like anorexia or bulimia. Use the appropriate F50 codes instead.
