Excludes1: never code together

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

  • postprocedural hypoparathyroidism (E89.2)
  • tetany NOS (R29.0)
  • transitory neonatal hypoparathyroidism (P71.4)

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

  • E83.5Disorders of calcium metabolism
  • R29.0Tetany
  • E83Disorders of mineral metabolism
