Adult osteomalacia due to malnutrition

This code signifies a metabolic bone disorder in adults characterized by defective mineralization of bone osteoid, leading to bone softening and weakness. It specifically points to malnutrition as the underlying cause, often due to inadequate intake or absorption of vitamin D, calcium, or phosphate.

Apply this code when documentation clearly indicates adult osteomalacia and explicitly links its etiology to nutritional deficiencies. This includes cases of severe dietary restrictions, malabsorption syndromes (e.g., celiac disease, Crohn's disease affecting nutrient absorption), or chronic alcoholism leading to nutritional compromise.

• Ensure documentation specifies "adult" osteomalacia to differentiate from rickets (pediatric form).
• Look for explicit mention of malnutrition, vitamin D deficiency, or other nutritional deficits as the cause.
• Consider sequencing additional codes for the specific type of malnutrition or malabsorption syndrome if documented.
