Specific personality disorders are coded in the F60 range: F60.3 for borderline, F60.0 paranoid, F60.1 schizoid, F60.2 antisocial, F60.4 histrionic, F60.5 obsessive-compulsive, F60.6 avoidant, F60.7 dependent, F60.81 narcissistic, and F60.9 unspecified. This guide maps every F60 code, groups them into the three DSM clusters, takes a closer look at borderline personality disorder (the presentation therapists see most), and covers the scope and documentation expectations that come with diagnosing a personality disorder.
Quick Reference: Personality Disorder ICD-10 Codes
| Code | Description | Notes |
|---|---|---|
| F60.0 | Paranoid personality disorder | Cluster A (odd/eccentric) |
| F60.1 | Schizoid personality disorder | Cluster A (odd/eccentric) |
| F60.2 | Antisocial personality disorder | Cluster B (dramatic/erratic) |
| F60.3 | Borderline personality disorder | Cluster B; most commonly seen in therapy |
| F60.4 | Histrionic personality disorder | Cluster B (dramatic/erratic) |
| F60.5 | Obsessive-compulsive (anankastic) personality disorder | Cluster C (anxious/fearful) |
| F60.6 | Avoidant personality disorder | Cluster C (anxious/fearful) |
| F60.7 | Dependent personality disorder | Cluster C (anxious/fearful) |
| F60.81 | Narcissistic personality disorder | Cluster B; note the two-decimal code |
| F60.89 | Other specific personality disorders | For specified disorders without a dedicated code |
| F60.9 | Personality disorder, unspecified | Temporary placeholder only |
Watch the two-decimal codes. Narcissistic personality disorder is F60.81 and other specific personality disorders is F60.89, not a single-decimal F60.8. Schizotypal disorder is F21, in a separate block, not part of the F60 range. Using the wrong level of specificity is a common claim-rejection trigger.
The Three Clusters
The DSM organizes the specific personality disorders into three clusters based on shared descriptive features. The clusters are a clinical convenience rather than ICD-10-CM billing categories, but they help you situate each F60 code and reason about differentials.
Cluster A (odd or eccentric):
- Paranoid (F60.0): pervasive distrust and suspiciousness, interpreting others' motives as malevolent.
- Schizoid (F60.1): detachment from social relationships and a restricted range of emotional expression.
Cluster A boundary: schizotypal disorder is not in this list. ICD-10-CM codes it as F21, alongside schizophrenia and other psychotic disorders, so keep it separate from schizoid personality disorder (F60.1).
Cluster B (dramatic, emotional, or erratic):
- Antisocial (F60.2): disregard for and violation of the rights of others.
- Borderline (F60.3): instability of relationships, self-image, and affect, with marked impulsivity.
- Histrionic (F60.4): excessive emotionality and attention seeking.
- Narcissistic (F60.81): grandiosity, need for admiration, and lack of empathy.
Cluster C (anxious or fearful):
- Avoidant (F60.6): social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation.
- Dependent (F60.7): a pervasive and excessive need to be taken care of, leading to submissive and clinging behavior.
- Obsessive-compulsive (F60.5): preoccupation with orderliness, perfectionism, and control. Also called anankastic personality disorder, and distinct from obsessive-compulsive disorder (F42.2).
Borderline Personality Disorder (F60.3)
The short answer: the ICD-10 code for borderline personality disorder is F60.3.
Borderline personality disorder is the personality disorder most commonly seen in outpatient therapy, and it is the one clinicians are most often asked to distinguish from mood disorders. The affective instability of BPD can look like a mood episode, but for the difference from bipolar disorder, see the comparison of bipolar disorder and borderline personality disorder, where the shift in the temporal pattern of mood changes is the key distinction.
When to use: a pervasive pattern of instability in interpersonal relationships, self-image, and affect, together with marked impulsivity, beginning by early adulthood and present across a range of contexts.
Documentation requirements:
- The pervasive, cross-situational, and enduring nature of the pattern, not an isolated episode
- Specific features present, such as frantic efforts to avoid abandonment, unstable relationships, identity disturbance, impulsivity, or recurrent self-harm
- Onset traceable to adolescence or early adulthood
- Clinically significant distress or functional impairment
- Why the presentation is a personality disorder rather than a mood or anxiety disorder
Scope and Documentation
Diagnosing a personality disorder should be within your scope of practice and thoroughly documented. Personality disorder diagnoses carry weight: they describe enduring patterns rather than episodic states, they can follow a client across records, and they are scrutinized by payers and reviewers. A few principles keep the diagnosis defensible:
Confirm scope: licensed clinicians who assess and diagnose within their state scope can make a personality disorder diagnosis. If your role or setting limits diagnostic authority, refer or consult rather than coding one.
Document the pervasive pattern: a personality disorder is defined by an enduring, inflexible pattern across a broad range of situations, not by a single presentation. Note the cross-situational and long-standing nature explicitly.
Establish onset: the pattern should trace back to adolescence or early adulthood. State this in the record.
Rule out alternatives: briefly document why the presentation is not better explained by another mental disorder, substance use, or a medical condition.
Billing note: reserve F60.9 (unspecified) for genuinely incomplete evaluations. Payers flag unspecified codes, and a pattern of F60.9 billing can trigger documentation requests. Specify the F60 code as soon as your assessment supports it.
Frequently Asked Questions
- What is the ICD-10 code for borderline personality disorder?
- The ICD-10-CM code for borderline personality disorder is F60.3. It sits in the F60 range of specific personality disorders and is the personality disorder most commonly seen in outpatient therapy. Document the pervasive pattern of instability in relationships, self-image, and affect, along with marked impulsivity, to support the diagnosis.
- What is the code for narcissistic personality disorder?
- Narcissistic personality disorder is F60.81. Note the two-decimal specificity: it is F60.81, not F60.8. F60.89 is reserved for other specific personality disorders that do not have their own dedicated code.
- What is the code for antisocial personality disorder?
- Antisocial personality disorder is F60.2. It belongs to Cluster B, the dramatic and erratic group, alongside borderline (F60.3), histrionic (F60.4), and narcissistic (F60.81) personality disorders.
- What is the ICD-10 code for a personality disorder, unspecified?
- Personality disorder, unspecified is F60.9. Use it only when a personality disorder is clearly present but you do not yet have enough information to specify which one. Move to a specific F60 code as soon as your assessment supports it, since payers scrutinize unspecified codes.
- Where does schizotypal personality disorder code?
- Schizotypal disorder is coded F21, not in the F60 range. ICD-10-CM places it in a separate block with schizophrenia and other psychotic disorders rather than with the specific personality disorders. This is a frequent miscode, so keep schizotypal (F21) distinct from schizoid personality disorder (F60.1).
Accurate personality disorder coding starts with the F60 range and the right level of specificity: F60.3 for borderline, F60.81 for narcissistic, and F60.9 only as a placeholder. Keep schizotypal (F21) out of the F60 family, ground each diagnosis in a documented pervasive pattern, and confirm the diagnosis is within your scope.
