Question 1

What is ICD-10 code F41.8?

Accepted Answer

F41.8 is the ICD-10-CM diagnosis code for other specified anxiety disorders. This code is used for anxiety disorders that have specific characteristics but don't fit into the standard anxiety disorder categories. F41.8 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders (f40-f48).

F41.8 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Always document the specific type of anxiety disorder being coded in the medical record.

Question 2

Is F41.8 an HCC code?

Accepted Answer

F41.8 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

Question 3

Is F41.8 billable?

Accepted Answer

Yes. F41.8 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. F41.8 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.

Question 4

Which HCC does F41.8 map to under V28?

Accepted Answer

F41.8 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

Question 5

What RAF reference is published for F41.8?

Accepted Answer

F41.8 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

Question 6

What is the V28 vs V24 difference for F41.8?

Accepted Answer

F41.8 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

Question 7

What documentation supports F41.8?

Accepted Answer

Always document the specific type of anxiety disorder being coded in the medical record Use this code only after ruling out F41.0, F41.1, and F41.3 F41.8 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Question 8

Can F41.8 be a primary diagnosis?

Accepted Answer

Yes. F41.8 carries no code-first instruction in the FY2026 tabular, so it can be the first-listed diagnosis when it is the condition chiefly responsible for the encounter and the note supports it, and it can also be reported as a secondary diagnosis. For risk adjustment the order does not matter; the V28 category is the same either way.

Question 9

Which codes cannot be reported with F41.8?

Accepted Answer

No Excludes1 note applies to F41.8 or its category in the FY2026 tabular, so there is no code the classification forbids alongside it. The Excludes2 note lists symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99); anxiety in: acute stress reaction (F43.0); transient adjustment reaction (F43.2); neurasthenia (F48.8); and 2 more (see the notes on this page); those are separate conditions that may be reported together with F41.8 when both are documented.
