Last updated: 3/24/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

Edema refers to the abnormal accumulation of fluid in body tissues, causing swelling. This code is used when a patient has documented swelling or fluid retention, but the underlying cause has not been determined or specified. Edema can occur in various parts of the body including the legs, feet, hands, face, or throughout the body. The swelling may be visible as puffiness or can be detected when pressing on the skin leaves a temporary indentation.

Additional Information

This is a symptom code, not a diagnosis of the underlying condition causing the edema. Further evaluation is typically needed to identify the root cause, which could range from heart, kidney, or liver conditions to medication side effects or other medical issues.
