About coding panic
The ICD-10-CM code for panic is F41.0 (Panic disorder [episodic paroxysmal anxiety]). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F41.0.
Within F41 (other anxiety disorders), F41.0 is specifically for panic disorder [episodic paroxysmal anxiety]. Related codes cover generalized anxiety disorder (F41.1), other mixed anxiety disorders (F41.3), other specified anxiety disorders (F41.8) and anxiety disorder, unspecified (F41.9).
Don't report F41.0 together with the conditions in its Excludes1 note: panic disorder with agoraphobia (F40.01).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
More specific panic codes (official index)

Don't confuse with (Excludes1 for F41.0)
