What is the correct code for senile dementia?

The code for senile dementia is F03.90. This code is part of the International Classification of Diseases, Tenth Revision (ICD-10), which classifies dementia not otherwise specified. Senile dementia, often characterized by an age-related decline in cognitive function, falls under this general category when a more specific diagnosis is not provided.

F03.90 specifically indicates a dementia diagnosis in the absence of additional qualifiers. This makes it suitable for cases like senile dementia, where the exact type of dementia may not be further specified, allowing for comprehensive coding of the condition.

The other codes listed correspond to different conditions. For instance, F32.9 denotes unspecified major depressive disorder, which is unrelated to dementia. F06.31 codes for dementia due to other conditions, and F17.223 pertains to nicotine dependence, which is entirely different. The selection of F03.90 reflects the need to accurately code senile dementia within its appropriate diagnostic framework in the ICD-10 classification.
