What ICD-10-CM code relates to dehydration?

• A. C79.31
• B. E86.0
• C. D69.3
• D. C85.16

Answer: (B)

The ICD-10-CM code that relates specifically to dehydration is E86.0. This code is defined for "dehydration," which encompasses a state where the body has lost more fluids than it has taken in, resulting in an imbalance that can affect bodily functions. This classification is important for accurately diagnosing and treating patients who are experiencing dehydration due to various causes, such as illness, excessive heat exposure, or inadequate fluid intake.

Using the correct code is essential for medical billing and records as it provides clarity on the patient's condition and guides appropriate treatment measures. It is a standardized code that healthcare providers and insurers utilize to communicate important information about the patient's health status.

In contrast, the other codes do not pertain to dehydration: C79.31 refers to secondary malignant neoplasm of bone, D69.3 is linked to thrombocytopenia due to conditions like an immune disorder, and C85.16 relates to peripheral lymphadenopathy due to lymphoid tissue neoplasm. Hence, E86.0 is the accurate choice for dehydration.
