  • ICD-9-CM 252.1 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 252.1 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes).
Convert to ICD-10-CM: 252.1 converts approximately to:
  • 2015/16 ICD-10-CM E20.9 Hypoparathyroidism, unspecified
Approximate Synonyms
  • Idiopathic hypoparathyroidism
  • Postoperative hypoparathyroidism
  • Post-surgical hypoparathyroidism
  • Tetanic cataract
Clinical Information
  • A condition caused by a deficiency of parathyroid hormone (or pth). It is characterized by hypocalcemia and hyperphosphatemia. Hypocalcemia leads to tetany. The acquired form is due to removal or injuries to the parathyroid glands. The congenital form is due to mutations of genes, such as tbx1; (see digeorge syndrome); casr encoding calcium-sensing receptor; or pth encoding parathyroid hormone
  • A disorder characterized by a decrease in production of parathyroid hormone by the parathyroid glands
  • An endocrine disorder characterized by decreased production of parathyroid hormone by the parathyroid glands. It is usually caused by damage of the parathyroid glands during head and neck surgery. Signs and symptoms include muscle cramps, abdominal pain, dry skin, brittle nails, cataracts, tetany, and convulsions
  • Condition produced by greatly reduced function of the parathyroids possibly due to autoimmune disease or genetic factors, or by the removal of those bodies; lack of parathyroid hormone leads to a fall in plasma calcium level, which may result in increase neuromuscular excitability and ultimately tetany followed by a rise in plasma phosphate level

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 252.1 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
