Obsessive-compulsive disorder (F42)
The ICD-10 codes under F42 cover obsessive-compulsive disorder (OCD) and related conditions, providing specific classifications to help pinpoint the exact type of OCD being diagnosed. These codes assist healthcare providers and coders in identifying and documenting various obsessive-compulsive symptoms accurately.
The code F42 represents general obsessive-compulsive disorder. More detailed codes like F42.2 specify mixed obsessional thoughts and acts, while F42.3 is assigned for hoarding disorder, often referred to simply as "hoarding." The F42.4 code is used for excoriation (skin-picking) disorder. The section also includes F42.8 for other OCD conditions involving various obsessions such as fears of contamination, harm, or rituals like hand washing. Finally, F42.9 is reserved for unspecified cases where the precise form of OCD is unclear or caused by substances. These specific ICD-10 codes are essential for accurately capturing the diversity of obsessive-compulsive disorders in clinical and billing settings.
