E20.89
Other specified hypoparathyroidism
Clinical Classification Guidelines
Inclusion Terms
- Familial hypoparathyroidism
Medical Intelligence & Overview
Other specified hypoparathyroidism, classified under ICD-10 code E20.89, is a condition where the parathyroid glands produce insufficient parathyroid hormone (PTH). This hormone plays a vital role in regulating calcium and phosphorus levels in the body. When PTH levels are low or absent, it leads to imbalances that can affect various bodily functions. The condition is termed 'other specified' because it encompasses forms of hypoparathyroidism that do not fall into more common categories, including familial cases. Understanding this condition involves reviewing its causes, symptoms, diagnosis, and potential management strategies.
Causes & Symptoms
Clinical Causes: Genetic factors: Some forms, like familial hypoparathyroidism, run in families due to inherited gene mutations. Autoimmune destruction: The body's immune system mistakenly targets and attacks the parathyroid glands. Surgical removal: Damage or removal of parathyroid tissue during surgery, especially thyroid operations. Radiation therapy: Exposure to radiation in neck or chest regions can impair gland function. Infections: Certain infections may lead to inflammation and damage of parathyroid glands. Congenital abnormalities: Developmental issues affecting the glands from birth. Other causes: Including infiltrative diseases or unknown reasons, classified under 'other specified' cases.
Key Symptoms: Muscle cramps and spasms (tetany) Numbness or tingling sensations, especially around the lips, fingertips, and toes Fatigue and weakness Loss of appetite, nausea, or vomiting Difficulty breathing or chest pain during severe episodes Convulsions in extreme cases Skin changes or dental abnormalities in some hereditary cases Cognitive disturbances or mood changes
Diagnostic & Treatment
Diagnosis Path: Diagnosis of other specified hypoparathyroidism involves blood tests that typically show low calcium levels (hypocalcemia) and possibly low or inappropriately normal PTH levels. Additional tests may include:
Treatment Protocols: Managing other specified hypoparathyroidism focuses on restoring calcium and vitamin D levels to alleviate symptoms and prevent complications. Common approaches include:
