About coding agoraphobia
The ICD-10-CM code for agoraphobia is F40.00 (Agoraphobia, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F40.00.
Within F40.0, choose F40.00 (unspecified) only when documentation doesn't support a more specific option: with panic disorder (F40.01) and without panic disorder (F40.02).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 882 (Neuroses Except Depressive, relative weight 0.9952), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
