ICD-10 Code F52.5 – Vaginismus not due to a substance or known physiological condition (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F52.5 – Vaginismus not due to a substance or known physiological condition
What it is
F52.5 identifies vaginismus when the vaginal muscles involuntarily tighten, making penetration difficult or impossible, and the cause is not a substance or known physical condition. Use it for a psychogenic or functional presentation after documentation supports that distinction.
Clinical signs
Typical findings include involuntary pelvic floor spasm, pain, fear, or avoidance with attempted vaginal penetration. Clinical features vary; refer to documentation, especially when the record describes anxiety, distress, or inability to tolerate examination or intercourse.
When to use this code
Use F52.5 when the clinician documents vaginismus and specifically indicates it is not due to a medication, substance, or recognized physiological disorder. It may apply in gynecologic, sexual health, or behavioral health notes when penetration is not possible because of muscle spasm or guarding.
Code only when the diagnosis is clearly stated or well supported in the record. If the chart suggests an underlying medical cause, check documentation before assigning this code.
Do not use for
Do not use F52.5 for pain from an identified pelvic, vaginal, or neurologic condition, or when the issue is documented as due to a substance. If the record does not clearly support vaginismus, check documentation.
Coding tip
Look for explicit wording that rules out physiologic or substance-related causes before assigning F52.5.
