Ever wonder how historical figures like Al Capone were clinically classified in their final days? ICD-10-CM code A52.17 represents general paresis, also known as dementia paralytica, which is a severe neuropsychiatric manifestation of late-stage neurosyphilis.

For medical coders, capturing this condition requires careful review of provider documentation to distinguish it from other forms of dementia. Understanding the sequencing rules for infectious manifestations is key to preventing diagnostic denials.
