What is ICD-10 code F95.8?

F95.8 is the ICD-10-CM diagnosis code for Other tic disorders. A condition characterized by involuntary, repetitive movements or sounds (tics) that don't fit into other specific tic disorder categories, such as motor tics affecting various body parts or vocal tics. F95.8 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F95.8 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. F95.8 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. F95.8 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.

What is the V28 vs V24 difference for F95.8?

F95.8 does not map to a payment HCC under either the CMS-HCC V28 risk adjustment model or the older V24 model. V28 reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition. Because neither model rewards F95.8 with a risk adjustment factor, it contributes zero to a Medicare Advantage beneficiary's RAF score in either version. Coders should check whether provider documentation supports a more specific child code that does map to a payment HCC.

What should coders know when reporting F95.8?

Use this code when the tic disorder doesn't meet criteria for Tourette's syndrome or other specified tic disorders Document the specific type and location of tics to support medical necessity and differentiate from other movement disorders

Audit Caution

HCC Buddy guidance

Using F95.8 when the presentation fits a standard tic disorder category — prefer specific codes

Confusing F95.8 with F95.9 — F95.8 is for specific atypical presentations, not for unspecified cases

Coding adult-onset tics as F95.8 without excluding medication-induced tics or tardive dyskinesia

Failing to document the specific atypical features that justify the 'other' classification

Common Mistakes

HCC Buddy guidance

F95.0 — Transient tic disorder; for tics present less than one year

F95.1 — Chronic motor or vocal tic disorder; for motor OR vocal tics lasting more than one year

F95.2 — Tourette's disorder; for motor AND vocal tics lasting more than one year

F95.9 — Tic disorder, unspecified; F95.8 requires identified atypical features while F95.9 is truly unspecified

Is F95.8 an HCC code?

No. F95.8 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.

RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for F95.8

For F95.8to 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 F95.8 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

F95.8 is the ICD-10-CM diagnosis code for other tic disorders. A condition characterized by involuntary, repetitive movements or sounds (tics) that don't fit into other specific tic disorder categories, such as motor tics affecting various body parts or vocal tics. F95.8 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering behavioral and emotional disorders with onset usually occurring in childhood and adolescence (f90-f98).

F95.8 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

F95.8 does not map to any HCC in V28 or V24 models. RxHCC maps to 133 (0.000). No risk adjustment impact. Coders reviewing F95.8 should check whether additional documentation would support a more specific child code in the same hierarchy that does map to a payment HCC, capturing the correct specificity is the highest-impact RAF improvement available within accurate coding.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F95.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Use this code when the tic disorder doesn't meet criteria for Tourette's syndrome or other specified tic disorders
•Document the specific type and location of tics to support medical necessity and differentiate from other movement disorders

Clinical Significance

This code captures tic disorders that are specifically identified but do not fit the standard categories of transient, chronic motor/vocal, or Tourette's disorder. This may include tic disorders with atypical features, adult-onset tic disorders, or tic-like presentations associated with specific neurological conditions. Documentation should specify the atypical nature of the presentation.

Documentation Requirements

✓Provider documentation of a tic disorder with atypical features
✓Description of the specific tics and why they do not fit standard tic disorder categories
✓Documentation of onset, duration, and course of the tic symptoms
✓Clinical rationale for using the 'other' category rather than a standard tic disorder code
✓Treatment plan addressing the tic symptoms

Commonly Confused Codes

•F95.0: Transient tic disorder; for tics present less than one year
•F95.1: Chronic motor or vocal tic disorder; for motor OR vocal tics lasting more than one year
•F95.2: Tourette's disorder; for motor AND vocal tics lasting more than one year
•F95.9: Tic disorder, unspecified; F95.8 requires identified atypical features while F95.9 is truly unspecified
