Code Description

ICD-10 M83 is a billable code used to indicate a diagnosis of adult osteomalacia.

Key Diagnostic Point:

Adult osteomalacia is a metabolic bone disorder characterized by the softening of bones due to inadequate mineralization, primarily caused by a deficiency of vitamin D, calcium, or phosphate. This condition leads to decreased bone density and an increased risk of fractures. In adults, osteomalacia can result from various factors, including malabsorption syndromes, chronic kidney disease, and certain medications that affect bone metabolism. Clinically, patients may present with bone pain, muscle weakness, and an increased susceptibility to fractures, particularly in weight-bearing bones. Diagnosis typically involves a combination of clinical evaluation, laboratory tests to assess vitamin D and mineral levels, and imaging studies such as X-rays or bone density scans to evaluate bone health. Treatment focuses on correcting the underlying nutritional deficiencies, often through supplementation and dietary modifications, alongside addressing any contributing medical conditions. Monitoring bone density and fracture risk is crucial in managing patients with osteomalacia to prevent complications.

Frequently Asked Questions

What is the primary cause of adult osteomalacia?

The primary cause of adult osteomalacia is a deficiency in vitamin D, which leads to inadequate mineralization of bone. Other contributing factors may include malabsorption syndromes, chronic kidney disease, and certain medications.
