ICD-10 Code F45.2 – Hypochondriacal disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F45.2 – Hypochondriacal disorders
What it is
F45.2 identifies a disorder where a person has persistent fear of having a serious illness despite limited or no medical evidence. Use it for hypochondriacal disorder when the concern is the main clinical problem.
Clinical signs
Common features include excessive worry about health, repeated self-checking, and frequent reassurance-seeking. Clinical features vary; refer to documentation if the presentation is unclear or overlaps with other somatic symptom conditions.
When to use this code
Use this code when the record documents hypochondriacal disorder, illness anxiety, or similar persistent disease fear as the primary diagnosis. It may apply when the patient repeatedly presents for evaluation but tests or exams do not support a serious illness. Check documentation if another somatic or anxiety disorder is better described.
Do not use for
Do not use it for a confirmed medical disease, or for nonspecific anxiety without documented health preoccupation. If the chart instead supports another somatic symptom disorder, code that condition instead.
Coding tip
Code F45.2 only when documentation clearly shows persistent illness fear and not just general worry.
