What is SIADH ICD 10 Code and What Does It Mean?
SIADH stands for Syndrome of Inappropriate Secretion of Antidiuretic Hormone. It is a condition where the body produces too much of a hormone called antidiuretic hormone (ADH), which helps regulate the balance of water and sodium in the body. When there is too much ADH, the kidneys retain too much water and dilute the blood, leading to hyponatremia or low sodium levels in the blood.
SIADH can be caused by various factors, such as brain injuries, tumors, infections, medications, lung diseases, or hormonal disorders. Some of the symptoms of SIADH include nausea, vomiting, headache, confusion, seizures, coma, or even death in severe cases.
SIADH is a medical diagnosis that can be coded using the International Classification of Diseases, 10th Revision (ICD-10). ICD-10 is a system of codes that classify diseases and health problems for statistical and billing purposes. The ICD-10 code for SIADH is E22.2. This code belongs to the category of E22 – Hyperfunction of the pituitary gland, which is part of the chapter of E00-E89 – Endocrine, nutritional, and metabolic diseases.
The ICD-10 code E22.2 can be used to indicate a diagnosis of SIADH for reimbursement purposes. However, it is important to note that code E22.2 does not specify the cause or severity of SIADH, and it may not capture all the relevant clinical information. Therefore, it is recommended to use additional codes or modifiers to provide more details about the condition. For example, some of the possible additional codes are:
– E87.1 – Hypo-osmolality and hyponatremia
– G93.1 – Anoxic brain damage, not elsewhere classified
– J18.9 – Pneumonia, unspecified organism
– T50.9 – Poisoning by unspecified drugs, medicaments, and biological substances
These codes are examples only and may not apply to every case of SIADH. The choice of codes depends on the clinical documentation and coding guidelines.
Conclusion
SIADH is when the body produces too much ADH, leading to hyponatremia. The ICD-10 code for SIADH is E22.2, but it may need additional codes to provide more details about the condition. SIADH can be a severe and life-threatening condition that requires prompt diagnosis and treatment.
