0.000What This Code Means
Anorexia nervosa with food restriction as the primary method of weight control, at moderate severity with noticeable functional impairment and some medical complications.
Coding Tips
- •Moderate severity indicates significant functional impairment and possible medical complications requiring closer monitoring
- •Document the specific severity indicators in the medical record to support this level of coding
Clinical Significance
Anorexia nervosa, restricting type involves weight loss achieved primarily through dieting, fasting, or excessive exercise without binge eating or purging behaviors. Moderate severity indicates BMI between 16 and 16.99 kg/m2, representing significant nutritional compromise requiring close monitoring. This subtype carries significant risk for malnutrition, cardiac arrhythmias, and osteoporosis.
Documentation Requirements
- ✓Documentation of restricting behaviors (dieting, fasting, excessive exercise) WITHOUT binge eating or purging
- ✓Current BMI or weight documenting severity level (BMI 16.00-16.99 kg/m2)
- ✓Distorted body image or intense fear of weight gain
- ✓Duration and course of illness
- ✓Medical monitoring results (vital signs, electrolytes, cardiac evaluation)
