R519 - Headache, unspecified type

International Classification of Diseases

Last updated: 10/3/2025

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

This code indicates you experienced a headache, but the specific type or cause wasn't determined or documented during your visit. Headaches are very common and can have many different causes, ranging from stress, dehydration, or lack of sleep to more specific medical conditions. Since this is coded as 'unspecified,' it means your healthcare provider documented that you had head pain but didn't identify it as a particular type of headache (like migraine, tension headache, or cluster headache). This could be because it was a one-time occurrence, the pattern wasn't clear yet, or additional evaluation might be needed to determine the specific type.

Additional Information

Most headaches are not serious, but persistent, severe, or changing headache patterns should be evaluated by a healthcare provider. This unspecified code is often used for initial visits or when the headache doesn't fit a specific pattern yet.
