SUBJECT:  Hoarding disorder

Q:

What is the correct code to assign for hoarding disorder?

A:

Hoarding disorder is characterized by persistent difficulty discarding or parting with possessions, regardless of their actual value, as a result of a strong perceived need to save the items and to distress associated with discarding them. Hoarding disorder results in the accumulation of a large number of possessions that congest and clutter active living areas to the extent that their intended use is substantially compromised (DSM-5, 2013).

ICD-10-AM and its parent classification ICD-10 do not have a specific code for hoarding disorder. Both the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5), published by the American Psychiatric Association and the World Health Organization (WHO) ICD-11 Beta Draft classify hoarding disorder to obsessive compulsive and related disorders.

Therefore, hoarding disorder should be classified to F42.8 Other obsessive-compulsive disorders following the index pathway:

Disorder (of)

- obsessive-compulsive

- - specified NEC F42.8

Additional codes such as Z58.8 Other problems related to physical environment and Z59.1 Inadequate housing should also be assigned where these situations are documented and meet the criteria in ACS 0002 Additional diagnoses.

Improvements to ICD-10-AM will be considered for a future edition.
