ICD-10 Code F45.29 – Other hypochondriacal disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F45.29 – Other hypochondriacal disorders
What it is
F45.29 identifies other hypochondriacal disorders, meaning persistent health anxiety or preoccupation with having a serious illness that is not better described by another diagnosis. Use it when the chart shows excessive illness concern rather than confirmed physical disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include repeated fear of illness, frequent checking or reassurance-seeking, and ongoing concern despite normal or nonexplanatory evaluations.
When to use this code
Use F45.29 when the clinician documents a hypochondriacal disorder, illness anxiety, or similar persistent preoccupation with health. It may fit encounters focused on distress about possible disease when workup does not support a specific medical condition. Check documentation if the note uses another somatic symptom or anxiety diagnosis.
Do not use for
Do not use this code for a confirmed medical illness, a brief worry about symptoms, or a different anxiety disorder that is specifically documented. If the record supports another F45 or F41 diagnosis, code that instead.
Coding tip
Code only when the provider clearly documents the disorder; if the note is vague, check documentation for the exact psychiatric diagnosis.
