M83: Adult osteomalacia

Non-billable headerICD-10-CM

M83 is a non-billable header ICD-10-CM code for adult osteomalacia. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • infantile and juvenile osteomalacia (E55.0)
  • renal osteodystrophy (N25.0)
  • rickets (active) (E55.0)
  • rickets (active) sequelae (E64.3)
  • vitamin D-resistant osteomalacia (E83.31)
  • vitamin D-resistant rickets (active) (E83.31)

Other codes that can never be billed with M83

Their own Excludes1 notes name this code, so the conflict is not listed above.

  • E55Vitamin D deficiency
  • K91.2Postsurgical malabsorption, not elsewhere classified
  • E83.3Disorders of phosphorus metabolism and phosphatases
  • E21Hyperparathyroidism and other disorders of parathyroid gland
