ICD 10 Code for Personality Disorder: Coding by Type, Documentation Rules & Claim Tips

Personality disorders require careful diagnosis coding because the correct ICD-10-CM code depends on the specific disorder documented by the qualified healthcare provider. For behavioral health practices, accurate personality disorder ICD 10 coding supports medical necessity, claim submission, reimbursement, and proper documentation.

The ICD-10-CM has several codes for particular personality disorders, but also codes for other defined personality disorder and unspecified personality disorder. Providers and coding teams should always assign the code that most accurately represents the recorded diagnosis, and not choose a code based on symptoms alone.

In practices that deliver mental or behavioral health services, accurate diagnosis coding needs to be coupled with appropriate CPT coding, documentation, insurance verification and claims management.

What Is the ICD 10 Code for Personality Disorder?

There is no single ICD 10 code for personality disorder. The proper code will vary depending on the type of personality disorder noted in the medical record.

F60 encompasses particular personality disorders, including paranoid, schizoid, antisocial, borderline, histrionic, obsessive-compulsive, avoidant, dependent and narcissistic personality disorders in FY2026. It also includes other specific and unspecified personality disorders.

ICD-10-CM is the system used by doctors in the United States to code and classify medical diagnoses. 2 The CDC describes it as the standardized method used to record and categories medical illnesses. Code sets may change by fiscal year thus billing teams should validate the applicable code set for the date of service.

Providers and coding teams can review the official ICD-10-CM resources from the CDC when verifying diagnosis codes, code updates, and coding guidance.

For Minnesota providers, this distinction matters when preparing behavioral health claims. A diagnosis code should accurately represent the provider’s documented clinical assessment and support the services reported on the claim.

Personality Disorder ICD 10 Codes by Type

The ICD 10 codes for personality disorder are primarily in the F60 group. They are part of the ICD-10-CM code set for FY2026.

F60.0 Paranoid personality disorder The clinician should document the diagnosis and differentiate it from other disorders that may be characterized by suspiciousness or paranoid symptoms.

The coder should not assign F60.0 just because the term “paranoid” is used in the patient record. The complete clinical assessment and documented diagnosis should guide code selection.

F60.1 – Schizoid Personality Disorder

F60.1 represents schizoid personality disorder. When assigning this code, the coding team should confirm that the provider has documented the specific personality disorder rather than inferring it from social or behavioral symptoms.

F60.2 – Antisocial Personality Disorder

F60.2 represents antisocial personality disorder. Documentation should clearly establish the provider’s diagnosis before this code is reported.

Because behavioral symptoms can overlap with other psychiatric conditions, coders should avoid selecting F60.2 based on isolated behaviors or assumptions.

F60.3 – Borderline Personality Disorder

F60.3 refers to a borderline personality disorder. The medical record should include a verified diagnosis and adequate clinical facts to justify the disease being treated.

Accurate diagnosis coding is particularly critical when many behavioral health problems are documented in a single record.

F60.4 – Histrionic Personality Disorder

F60.4 is assigned for histrionic personality disorder. Coding teams should rely on the provider’s documented diagnosis rather than attempting to interpret personality traits independently.

F60.5 – Obsessive-Compulsive Personality Disorder

F60.5 Obsessive-compulsive personality disorder. This diagnosis should not be automatically conflated with obsessive compulsive disorder which is under a different ICD-10-CM category.

This distinction is a good one to keep in mind while examining behavioral health paperwork and picking the right ADHD, OCD or personality disorder ICD 10 diagnosis when several illnesses are indicated.

F60.6 – Avoidant Personality Disorder

F60.6 represents avoidant personality disorder. The provider’s assessment should support the diagnosis before the code is submitted on a claim.

F60.7 – Dependent Personality Disorder

F60.7 is used for dependent personality disorder. Coders should confirm that the provider has specifically established the diagnosis and documented the clinical basis for treatment.

F60.81 – Narcissistic Personality Disorder

F60.81 represents narcissistic personality disorder. The CDC’s FY2026 ICD-10-CM index identifies narcissistic personality disorder under F60.81.

F60.89 – Other Specific Personality Disorders

F60.89 is used for other specific personality disorders when the provider documents a specific disorder that does not have its own individual code within the F60 category.

The documentation should make the specific condition clear enough to support the use of an “other specified” code.

F60.9 – Personality Disorder, Unspecified

F60.9 represents personality disorder, unspecified. It may be appropriate when the provider documents a personality disorder but does not establish a more specific type.

However, coders should review the complete record before automatically selecting F60.9.

How to Choose the Correct Personality Disorder ICD 10 Code

Selecting the correct personality disorder ICD 10 code starts with the provider’s documented diagnosis.

A practical coding workflow includes:

1. Review the assessment and diagnostic statement.
2. Identify the specific personality disorder documented.
3. Confirm that the documentation supports the diagnosis.
4. Check the current ICD-10-CM code set.
5. Review additional documented conditions.
6. Match the diagnosis with the services reported.
7. Complete a claim-level quality check before submission.

Coders are not permitted to diagnose the patient. The task is to translate the documented diagnosis of the physician into the correct ICD-10-CM code.

Professional medical coding services help clinics maintain consistency in their coding processes and minimize the number of avoidable claim errors.

Personality Disorder Documentation Requirements

Strong documentation is essential for accurate personality disorder coding. A behavioral health record should clearly identify the condition being assessed or treated and provide enough clinical information to support the services performed.

Depending on the encounter, documentation may include:

• Provider’s diagnostic assessment
• Relevant clinical findings
• Symptoms and functional impact
• Treatment goals
• Treatment plan
• Interventions performed
• Patient response to treatment
• Medical necessity
• Relevant comorbid conditions
• Date of service and provider information

Documentation must be consistent across the assessment, treatment plan, progress note, diagnostic list and claim.

For example, if the provider documents borderline personality disorder but the claim has an unclear personality disorder code, the difference may need to be reviewed before submission.

Common Personality Disorder Coding Errors

Coding From Symptoms Instead of the Diagnosis

Symptoms such as interpersonal difficulties, impulsivity, social withdrawal, or emotional instability do not automatically establish a specific personality disorder. The provider’s diagnosis should drive code selection.

Confusing Similar Behavioral Health Diagnoses

Some psychiatric conditions can share overlapping symptoms. Coders should carefully distinguish the documented diagnosis instead of assuming that similar symptoms represent the same disorder.

Overusing F60.9

F60.9 can be appropriate when the documentation supports an unspecified personality disorder. However, it should not replace a more specific code when the provider has clearly documented a specific personality disorder.

Selecting an Unsupported Specific Code

The opposite problem can also occur. A coder should not select a specific personality disorder code simply because certain symptoms appear in the record.

Ignoring Comorbid Conditions

Patients may have more than one documented behavioral health condition. Coders should review the complete record and follow applicable coding guidelines for reporting additional diagnoses.

Using the Wrong Code Set

ICD-10-CM releases change over time. The CDC currently identifies FY2027 as the release beginning October 1, 2026, replacing the FY2026 release for services in the new fiscal-year period.

Personality Disorder Coding for Behavioral Health Practices

Psychiatrists, psychologists, therapists, psychiatric clinics, and other behavioral health providers may meet diagnoses of personality disorders in the continuous treatment of patients.

Appropriate coding fortifies the link between the diagnosis recorded and the services performed. It also can help billing teams uncover anomalies before claims get to the payer.

Behavioral health practices need a system that links clinical data, CPT codes, ICD-10-CM diagnoses, payer requirements and claim filing.

Specialized behavioral health billing services can help large-volume-claims practices by offering support throughout the revenue cycle.

Personality Disorder CPT Coding and Diagnosis Matching

An ICD-10-CM diagnosis code identifies the patient’s documented condition, while CPT codes generally describe the service performed.

These code sets serve different purposes but must work together on a claim.

For example, a behavioral health encounter could be a psychiatric evaluation, a psychotherapy service, or other covered service. The diagnosis code should represent the ailment that was noted and treated at the interaction.

A coding review should therefore ask:

• Does the diagnosis match the provider’s documentation?
• Does the CPT code accurately describe the service?
• Does the documentation support the reported service?
• Are payer-specific requirements satisfied?
• Are modifiers or other claim information appropriate?

This type of review can reduce preventable billing problems.

Personality Disorder Claims and Denial Prevention

A successful claim submission includes more than just accurate diagnosis coding. Claims can also be problematic because of eligibility, authorization, documentation, provider enrolment, payer revisions or conflicts between claim information and medical records.

Billing teams should validate patient coverage, verify the coding, verify provider information, verify authorization requirements (if applicable) and do a last review of the claim before submitting it for behavioral health.

Practices can also use denial management services to identify recurring rejection patterns and address their underlying causes.

For additional information on Medicare behavioral health billing resources, providers can review the CMS behavioral health integration resources.

A denial should not always be treated as an isolated billing error. Reviewing denial trends can reveal recurring documentation, coding, authorization, or payer-specific issues.

Medical Billing Services for Personality Disorder Practices

Behavioral health practices often manage complex administrative requirements while trying to maintain consistent patient care. Outsourcing medical billing services can shift routine revenue cycle tasks to a specialized team.

A comprehensive billing workflow may include:

• Patient eligibility verification
• Charge entry
• ICD-10-CM and CPT coding
• Claim submission
• Payment posting
• Accounts receivable follow-up
• Denial management
• Appeals
• Patient billing
• Revenue cycle reporting

Patient statements are also an important part of the billing cycle because they communicate remaining balances to patients after insurance processing.

Minnesota Billing Services offers medical billing, coding, eligibility verification, credentialing, denial management and A/R follow-up for providers.

If you’ve got a Minnesota practice seeking for a medical billing firm, you’ll want to find a staff with experience in behavioral health coding to develop a more unified billing procedure.

Mental Health Billing Services for Personality Disorders

Personality disorder claims fall within the broader behavioral health billing environment. Mental health practices may deal with specialized documentation requirements, payer policies, authorization procedures, and recurring claim follow-up.

Minnesota Billing Services provides mental health billing services for behavioral health clinics, therapists, psychiatrists, psychologists, hospitals, and telepsychiatry services. Its listed services include insurance verification, authorization, coding and documentation review, credentialing, claims follow-up, and denial management.

This makes mental health billing services a natural consideration for practices treating patients with personality disorders and other behavioral health conditions.

Personality Disorder Claim Denial Management

Denial prevention should begin before a claim is submitted. Billing teams can review the most common causes of rejected or denied claims and establish corrective workflows.

Common areas to monitor include:

• Incorrect or incomplete diagnosis coding
• Documentation inconsistencies
• Eligibility problems
• Missing authorization
• Provider enrollment issues
• Incorrect patient information
• CPT and diagnosis mismatches
• Untimely claim submission

A structured claim denial management process should identify the reason for the denial, correct the underlying issue, submit an appeal or corrected claim when appropriate, and track the final outcome.

Practices can also review their accounts receivable management process to identify claims that remain unpaid after initial submission.

Credentialing and Revenue Cycle Considerations

Provider enrollment and credentialing can directly affect a practice’s ability to submit claims and receive payment. Behavioral health practices may need credentialing support when adding providers, changing payer participation, or expanding services.

Professional medical credentialing services can help manage applications, payer enrollment, recredentialing, and provider information.

Minnesota Billing Services states that its credentialing services support physicians, therapists, LCSWs, mental health professionals, solo practices, and multi-provider clinics.

For behavioral health organizations, credentialing should therefore be considered part of the broader revenue cycle rather than an isolated administrative task.

How to Improve Personality Disorder Billing Accuracy

A practical improvement plan can include five steps:

1. Standardize documentation reviews.
   Create a consistent process for checking diagnosis documentation before claims are submitted.
2. Keep coding references current.
   Verify the applicable ICD-10-CM release based on the date of service.
3. Separate diagnosis from assumption.
   Code the provider’s documented diagnosis rather than interpreting symptoms independently.
4. Monitor denial trends.
   Track recurring denial reasons and correct workflow problems that repeatedly affect claims.
5. Review the entire revenue cycle.
   Coding accuracy alone cannot resolve eligibility, authorization, credentialing, A/R, or payer-related problems.

These steps can help behavioral health practices create a more reliable revenue cycle management process.

Final Thoughts on the ICD 10 Code for Personality Disorder

The ICD 10 code for personality disorder will vary based on the provider’s documentation of the particular diagnosis. The category F60 has a number of type-specific codes as well as codes for various particular and unspecified personality disorders.

Accurate coding of personality disorder involves more than selecting a diagnosis from a code list. Providers need to have that documentation clear, and coding and billing teams need to verify the ICD-10-CM code, connect diagnoses to reported services, examine payer criteria, and keep track of claims once they’re submitted.

Accurate medical coding, mental health billing, denial management, credentialing, and revenue cycle processes can help behavioral health practices in Minnesota build a more consistent approach to reimbursement.
