Z15.2

Genetic susceptibility to obesity

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/12/2025

Code Description

ICD-10 Z15.2 is a billable code used to indicate a diagnosis of genetic susceptibility to obesity.

Key Diagnostic Point:

Z15.2 indicates a genetic predisposition to obesity, which is a significant public health concern due to its association with various chronic diseases such as diabetes, cardiovascular diseases, and certain cancers. This code is essential for identifying patients who may require tailored preventive strategies and interventions based on their genetic background. Social determinants of health, including socioeconomic status, access to healthy food, and physical activity opportunities, play a crucial role in managing obesity risk. Preventive care may involve lifestyle counseling, nutritional education, and regular screenings for weight-related health issues. Screening for obesity-related conditions is vital, particularly in populations with a known genetic susceptibility. Aftercare may include ongoing support for weight management and monitoring of associated health conditions. Accurate documentation of genetic factors and their implications for health status is critical for effective coding and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for comprehensive patient history including family history of obesity
  • Integration of social determinants of health into patient care plans
  • Potential for comorbid conditions requiring additional coding
  • Variability in clinical presentation and management strategies

Audit Risk Factors

  • Inadequate documentation of genetic factors influencing obesity
  • Failure to link Z15.2 with appropriate preventive or screening codes
  • Misclassification of obesity-related conditions without proper coding
  • Lack of evidence for lifestyle interventions in the medical record
