ICD-10 Code F45.41 – Pain disorder exclusively related to psychological factors (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F45.41 – Pain disorder exclusively related to psychological factors
What it is
This code describes pain that is primarily linked to psychological factors rather than a medical condition. Use it when the record supports a mental health-related pain disorder as the main diagnosis.
Clinical signs
Patients typically report persistent pain with psychological features affecting onset, severity, or persistence. Clinical features vary; refer to documentation.
When to use this code
Use F45.41 when the clinician documents pain disorder exclusively related to psychological factors and does not identify a physical cause as the primary explanation. Code it only when the note clearly supports a psychological basis for the pain. If the documentation is vague, check documentation before assigning the code.
Do not use for
Do not use this code for pain with a confirmed medical etiology or for pain that is better described by another documented condition. Do not assume the diagnosis from symptoms alone.
Coding tip
Assign this code only when the provider explicitly links the pain to psychological factors and documents it as the active diagnosis.
