Renal osteodystrophy

This code represents a bone disease resulting from chronic kidney disease and its associated metabolic derangements. It encompasses a spectrum of skeletal abnormalities, including osteitis fibrosa cystica, osteomalacia, adynamic bone disease, and mixed uremic osteodystrophy. These conditions arise from imbalances in calcium, phosphorus, parathyroid hormone, and vitamin D metabolism due to impaired renal function.

Use this code when documentation clearly indicates a diagnosis of renal osteodystrophy in a patient with chronic kidney disease. This diagnosis is typically supported by laboratory findings (e.g., elevated PTH, abnormal calcium/phosphorus), bone biopsy results, and radiographic evidence of skeletal changes. It should be assigned when the bone disorder is directly attributed to kidney dysfunction.

• Do not use this code for metabolic bone disorders not directly caused by renal failure; refer to the Excludes2 note for E70-E88.
• Always code the underlying chronic kidney disease (CKD) first, as renal osteodystrophy is a complication of CKD.
• Ensure documentation specifies "renal osteodystrophy" or a specific type of bone disease clearly linked to kidney failure.
