Other drug-induced osteomalacia in adults
ICD-10 M83.5 is a billable code used to indicate a diagnosis of other drug-induced osteomalacia in adults.
M83.5 refers to a specific type of osteomalacia that occurs in adults due to the effects of certain medications. Osteomalacia is characterized by the softening of bones, which can lead to bone pain, muscle weakness, and an increased risk of fractures. Drug-induced osteomalacia can result from various medications, including anticonvulsants, certain antibiotics, and medications that affect vitamin D metabolism. These drugs can interfere with the body's ability to absorb calcium and phosphate, essential minerals for maintaining bone density and strength. As a result, patients may experience symptoms such as bone tenderness, deformities, and fractures, particularly in weight-bearing bones. Diagnosis typically involves a combination of clinical evaluation, imaging studies, and laboratory tests to assess bone mineral density and metabolic function. Treatment focuses on addressing the underlying medication use, supplementing with vitamin D and calcium, and monitoring bone health to prevent further complications.
Detailed medication history, lab results for calcium and vitamin D levels, and bone density tests.
Patients presenting with bone pain and a history of anticonvulsant use.
Consideration of other endocrine disorders that may affect bone metabolism.
Comprehensive assessment of joint and bone health, including imaging studies.
Patients with autoimmune conditions on long-term corticosteroids presenting with bone pain.
Differentiating between drug-induced osteomalacia and other rheumatologic conditions affecting bone health.
Used to assess bone density in patients suspected of having osteomalacia.
Document the reason for the bone density test and any relevant clinical findings.
Endocrinologists may require additional lab tests to evaluate metabolic bone disease.
Common medications include anticonvulsants like phenytoin and phenobarbital, certain antibiotics such as tetracyclines, and medications that affect vitamin D metabolism, like glucocorticoids.
