About coding social phobia
The ICD-10-CM code for social phobia is F40.10 (Social phobia, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F40.10.
Within F40.1, choose F40.10 (unspecified) only when documentation doesn't support a more specific option: generalized (F40.11).
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.
