ICD-11 6C72 diagnostic criteria for CSBD

Compulsive Sexual Behavior Disorder is defined in the World Health Organization's International Classification of Diseases, 11th Revision, under code 6C72, in the chapter on impulse control disorders. This page walks through the diagnostic criteria as the ICD-11 states them, explains what each criterion is actually asking, and describes how the criteria are applied clinically. This is the same framework Iron Ridge uses to formulate cases and to determine whether the CSBD diagnosis is the right one for a specific patient.

Where the diagnosis sits in the ICD-11

CSBD is coded in the impulse control disorders chapter of the ICD-11, not in the substance use or addictive disorders chapter. This placement was deliberate. The WHO working group that finalized the diagnosis reviewed the evidence for treating CSBD as an addictive disorder and concluded that the phenomenology and the evidence base fit an impulse control framework better than an addictive-behavior framework. See CSBD vs. sex addiction for how that placement interacts with the sex-addiction framework, and see DSM-5-TR coding when CSBD is the clinical picture for how U.S. clinicians handle the fact that CSBD is not currently in the DSM-5-TR.

The full ICD-11 code is 6C72. Iron Ridge uses this code as the formal diagnostic anchor in all clinical documentation involving CSBD.

The core diagnostic language

The ICD-11 defines CSBD as follows:

A persistent pattern of failure to control intense, repetitive sexual impulses or urges resulting in repetitive sexual behavior over an extended period (e.g., 6 months or more) that causes marked distress or significant impairment in personal, family, social, educational, occupational, or other important areas of functioning.

Every clinical formulation of a CSBD case is a formulation against this sentence. The next sections unpack what each piece of it means in practice.

Criterion 1: Persistent pattern of failure to control

The word that carries the diagnostic weight is "control." CSBD is not defined by the presence of sexual urges, by their intensity, or by the frequency of sexual behavior. It is defined by the failure to regulate them. See loss of control over sexual behavior for the extended treatment of this criterion.

Clinically, this is assessed by asking what the person has attempted, on their own, to change the pattern. A person who has never tried to modify the behavior has not yet produced the evidence base to know whether they can control it. A person who has repeatedly attempted to modify the behavior and has been unable to sustain the change is producing the pattern the criterion describes. See failed attempts to stop sexual behavior.

The word "persistent" places a durational threshold on this. Isolated periods of dysregulation — a period of high stress, a specific life transition, a discrete situational trigger — do not meet criterion. The pattern has to be present across time. The ICD-11 specifies six months or more as the durational floor.

Criterion 2: Intense, repetitive sexual impulses or urges

The urges themselves are described as intense and repetitive. The subjective experience is that the urges arrive with force and that they arrive again after being acted on or resisted. Frequency of urges is not, by itself, the diagnostic feature — a person can experience frequent sexual urges without meeting the disorder — but the combination of intensity, repetition, and the pattern of behavior that follows is part of what the diagnosis describes.

This is also the criterion that separates CSBD from OCD with sexual content. In OCD, the sexual thoughts are unwanted, intrusive, and ego-dystonic — the person does not experience them as their own urges. In CSBD, the urges are ego-syntonic. The person experiences them as their own sexual interest. The regulatory problem is what the person does about them.

Criterion 3: Repetitive sexual behavior over an extended period

The behavior — not just the urge — has to be persistently present. This is what distinguishes CSBD from a person who experiences frequent unwanted urges but does not act on them. The behavior can take many forms: pornography use, sexual encounters, use of paid sexual services, specific behavioral patterns the person is repeating. What matters clinically is that a behavioral pattern is present, that it is repetitive, and that it has been in place over an extended period.

Criterion 4: Marked distress or significant impairment

Marked distress or significant impairment is not optional. It is a required criterion. Without either, the diagnosis does not apply. This is one of the places the ICD-11 was explicit about protecting the diagnosis from misuse. A person with elevated sexual interest, whose behavior does not produce distress or impairment, does not meet criterion — even if a partner or a third party thinks the behavior should be pathologized. See CSBD vs. high libido.

Impairment is assessed across personal, family, social, educational, occupational, and financial domains. Common impairment findings include:

• Relational damage — a partner discovering the pattern, a marriage in crisis, a family that has fractured. See relational impairment from CSBD.
• Occupational damage — hours lost at work, performance decline, discovery at work, termination. See occupational impairment from CSBD.
• Financial damage — significant expenditures on sexual services, on subscription content, or on other behaviors within the pattern. See financial consequences of CSBD.
• Legal exposure — behaviors that have brought the person into contact with the legal system.
• Physical health consequences.

Marked distress is not the same as situational discomfort. It is sustained. It is disproportionate to what the person can attribute to any single event. It persists across time even when the behavior is temporarily interrupted.

Criterion 5: Continued behavior despite consequences and diminishing satisfaction

The ICD-11 adds two related features that appear in the guidelines around the core criteria. Both matter clinically.

The behavior continues despite adverse consequences. The person is producing the consequences and continuing anyway. This is not the same as "not knowing better." The person knows. The behavior continues. See continued sexual behavior despite consequences.

The behavior continues despite little or no satisfaction from it. This is a phenomenological feature that appears reliably in CSBD presentations. The behavior stops producing the reward it once produced. The person is engaging in it anyway. This is one of the features that distinguishes CSBD from behavior that is simply a lifestyle choice.

What the diagnosis explicitly does not include

The ICD-11 was explicit about what CSBD is not, and this matters.

CSBD is not diagnosed on the basis of moral, religious, or cultural disapproval of a person's sexual behavior. The clinician does not formulate a case on the basis that the behavior is outside cultural or religious norms.

CSBD is not diagnosed on the basis of psychological distress that is entirely attributable to moral judgment about sexual behavior. A person who is distressed only because they think their behavior is wrong, in the absence of loss of control and impairment, is describing a values conflict, not a disorder.

CSBD is not diagnosed on the basis of a partner's preferred level of sexual frequency being lower than the patient's.

CSBD is not diagnosed on the basis of specific sexual behaviors that a clinician personally finds objectionable.

A competent clinician working in this area declines to formulate a CSBD diagnosis when the criteria are not met, regardless of what pressure exists to do so. See CSBD vs. high libido for the extended treatment of this issue.

How Iron Ridge applies these criteria

When a patient reaches out to Iron Ridge, the initial consultation is oriented around these criteria. The clinical conversation is designed to assess whether the pattern the person is describing meets ICD-11 6C72, and to do so honestly — which includes saying so directly when the criteria are not met. When the criteria are met, the CSBD diagnosis is entered into the clinical record and CSBD-specific treatment is offered. When the criteria are not met, or when a different formulation fits better, Iron Ridge says so and refers appropriately. See CSBD vs. OCD, CSBD vs. bipolar hypersexuality, and CSBD vs. high libido for the common alternate formulations.

What to do next

If the criteria described here describe a familiar pattern, a clinical consultation is the next step. The consultation is a clinical conversation, not a sales call. Its purpose is to make an honest determination of whether ICD-11 6C72 applies, and to decide together what to do about it if it does.
