What This Code Means

Bone disease that develops when kidneys fail to properly regulate calcium and phosphorus, leading to weak and brittle bones.

Coding Tips

•This is a chronic complication of kidney disease; verify stage of CKD for complete coding
•May require additional codes for specific bone manifestations if documented

Clinical Significance

Renal osteodystrophy represents bone disease secondary to chronic kidney disease, indicating CKD-mineral bone disorder requiring specialized management. This condition reflects complex metabolic complications of kidney disease affecting calcium-phosphorus homeostasis and bone health, requiring ongoing monitoring and treatment.

Documentation Requirements

✓Renal osteodystrophy clearly documented
✓Underlying chronic kidney disease documented and coded
✓Evidence of bone disease related to kidney dysfunction
✓Laboratory values showing calcium, phosphorus, or PTH abnormalities
✓Imaging studies showing bone changes if applicable
✓Treatment plan for CKD-mineral bone disorder
✓Monitoring schedule for bone health parameters
