M83.5
Other drug-induced osteomalacia in adults
Clinical Classification Guidelines
Use Additional Code
- code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
Medical Intelligence & Overview
Other drug-induced osteomalacia in adults, classified under ICD-10 code M83.5, is a condition where certain medications lead to softening of the bones due to defective mineralization. Osteomalacia often results from deficiencies in vitamin D or phosphate, but in this case, medications interfere with normal bone metabolism. Recognizing and understanding this condition is essential for managing symptoms and preventing complications associated with weakened bones in adults.
Causes & Symptoms
Clinical Causes: Use of specific medications such as long-term anticonvulsants Certain antifungal drugs that impair vitamin D metabolism Cytotoxic agents used in chemotherapy that affect bone healing Supplements or medications that interfere with phosphate absorption Other drugs that impair the kidney's ability to activate vitamin D
Key Symptoms: Bone pain, especially in the hips, pelvis, or lower back Muscle weakness and fatigue Difficulty walking or standing for long periods Fragile bones that may fracture easily Tenderness in affected bones Potential weight loss and general malaise in some cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of clinical evaluation, medical history, and laboratory tests. Blood tests usually show low levels of phosphate and vitamin D, with elevated alkaline phosphatase levels. Imaging studies like X-rays can reveal osteomalacia-related bone demineralization. Sometimes, bone biopsies are performed for confirmation. Healthcare providers review medication history to identify drugs that could cause osteomalacia, aiding in diagnosis.
Treatment Protocols: Managing drug-induced osteomalacia typically involves discontinuing or adjusting the offending medication under medical supervision. Supplementation with vitamin D and phosphate may be recommended to restore mineral levels. Physical therapy can assist in improving muscle strength and mobility. Regular monitoring through blood tests and imaging helps track recovery. Addressing the underlying causes and modifying medication use are crucial steps in treatment planning.
