About coding Gephyrophobia
The ICD-10-CM code for Gephyrophobia is F40.242 (Fear of bridges).
Within F40.24 (situational type phobia), F40.242 is specifically for fear of bridges. Related codes cover Claustrophobia (F40.240), Acrophobia (F40.241), fear of flying (F40.243) and other situational type phobia (F40.248).
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.
