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