What is ICD-10 code F60.3?

F60.3 is the ICD-10-CM diagnosis code for Borderline personality disorder. A personality pattern characterized by unstable relationships, intense fear of abandonment, impulsive behaviors, and emotional instability. It belongs to the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99). F60.3 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F60.3 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. F60.3 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. F60.3 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does F60.3 map to under V28?

F60.3 maps to CMS-HCC V28 HCC 153 (Personality Disorders; Anorexia/Bulimia Nervosa). The category numbers, labels, and conditions come from the CMS-HCC V28 model file for payment year 2026.

What documentation supports F60.3?

Document specific examples of relationship instability, self-harm behaviors, or identity disturbance Ensure criteria are met across multiple life domains and not attributable to another mental disorder or medical condition Because F60.3 maps to an HCC category, the documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment. See the MEAT criteria checklist at /meat-criteria for what Monitor, Evaluate, Assess, or Treat looks like in a note. MEAT is generic documentation evidence, not a payer-specific rule.

Buddy Documentation Tip

HCC Buddy guidance

Documentation of pervasive pattern of instability in relationships, self-image, and affect with impulsivity beginning by early adulthood

Evidence of at least five DSM-5 criteria (frantic avoidance of abandonment, unstable relationships, identity disturbance, impulsivity, recurrent suicidal behavior/self-harm, affective instability, chronic emptiness, inappropriate anger, transient paranoia/dissociation)

Pattern is enduring and pervasive, not limited to mood episodes

Assessment of current self-harm and suicidal risk

Audit Caution

HCC Buddy guidance

Confusing borderline personality disorder with bipolar disorder — they can coexist, but the mood instability patterns differ (reactive vs. episodic)

Diagnosing borderline personality disorder based solely on self-harm behavior without documenting the pervasive personality pattern

Coding borderline personality disorder during an acute mood episode or PTSD exacerbation when personality traits may be mimicked

Reluctance to code this diagnosis due to stigma when documentation clearly supports it — accurate coding enables appropriate treatment

Common Mistakes

HCC Buddy guidance

F31.x (Bipolar disorder) — mood cycling in bipolar is episodic; borderline mood shifts are rapid (hours to days) and reactive

F43.10 (PTSD, unspecified) — complex PTSD overlaps significantly but is a response to trauma, not a personality pattern per se

F60.2 (Antisocial personality disorder) — impulsivity and recklessness overlap, but borderline features fear of abandonment and emotional dysregulation

F60.4 (Histrionic personality disorder) — attention seeking and emotionality overlap, but borderline includes self-harm and identity disturbance

Is F60.3 an HCC code?

Yes. F60.3 (Borderline personality disorder) maps to HCC 153, Personality Disorders; Anorexia/Bulimia Nervosa under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.396. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.

Coder answer: F60.3 is billable and maps to V28 HCC 153, Personality Disorders; Anorexia/Bulimia Nervosa. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

Not separately weighted

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT Criteria for F60.3

For F60.3 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed F60.3 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

F60.3 is the ICD-10-CM diagnosis code for borderline personality disorder. A personality pattern characterized by unstable relationships, intense fear of abandonment, impulsive behaviors, and emotional instability. F60.3 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering disorders of adult personality and behavior (f60-f69).

Under the CMS-HCC V28 risk adjustment model, F60.3 maps to Personality Disorders; Anorexia/Bulimia Nervosa (HCC 153) with a source-labeled community, non-dual, aged reference coefficient of 0.396. No V24 mapping is shown for F60.3; use the applicable model and payment year when reviewing the V28 mapping. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.

Document specific examples of relationship instability, self-harm behaviors, or identity disturbance. Because F60.3 maps to an HCC category, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for F60.3 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Document specific examples of relationship instability, self-harm behaviors, or identity disturbance
•Ensure criteria are met across multiple life domains and not attributable to another mental disorder or medical condition

Clinical Significance

Borderline personality disorder is characterized by pervasive instability of interpersonal relationships, self-image, and affect, with marked impulsivity. It is the most commonly diagnosed personality disorder in clinical settings and carries a 10% lifetime suicide rate. Patients frequently present to emergency departments for self-harm, suicidal gestures, and emotional crises, making it a high-resource utilization condition.
