ICD-10 Code F63.1 – Pyromania (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F63.1 – Pyromania
What it is
Pyromania is a disorder marked by deliberate fire-setting driven by tension, fascination, or relief after starting fires. Use this code for the psychiatric condition, not for accidental fires or criminal arson without the disorder.
Clinical signs
Typical features include repeated fire-setting, preoccupation with fire, and a sense of excitement before the act. Clinical features vary; refer to documentation.
When to use this code
Use F63.1 when the record clearly documents pyromania or a clinician diagnoses the impulse-control disorder. It may apply in behavioral health assessments, psychiatric admissions, or outpatient notes describing recurrent intentional fire-setting with the characteristic urge pattern.
If the chart only states fire-related misconduct, property damage, or suspected intent without a psychiatric diagnosis, check documentation before coding. Confirm that the provider links the behavior to pyromania rather than another mental disorder or legal issue.
Do not use for
Do not use this code for arson, accidental fires, or general destructive behavior without pyromania. Do not assign it when the documentation supports another diagnosis or does not clearly identify the disorder.
Coding tip
Code F63.1 only when the provider documents pyromania explicitly or describes the classic impulse-control pattern.
