F41.0 — Panic disorder [episodic paroxysmal anxiety]
F41.0 is a billable, specific ICD-10-CM code for panic disorder [episodic paroxysmal anxiety]. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- panic disorder with agoraphobia (F40.01)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Panic attack
- Panic state
Other codes that can never be billed with F41.0
These codes carry an Excludes1 note pointing at F41.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F41.0 alone.
- F40.01Agoraphobia with panic disorder
Risk adjustment
F41.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
F41.0 is named in 35 Medicare coverage policies — 34 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
