Dementia is a general term for loss of memory, language, problem-solving and other thinking abilities that are severe enough to interfere with daily life. ICD-Code F03.90 is a billable ICD-10 code used for Unspecified Dementia without Behavioral Disturbance. Its corresponding ICD-9 code is 294.2. Read

Basic ICD-10 INFORMATION
World Health Organization (WHO) authorized the publication of the International Classification of DiseasesExternal 10th Revision (ICD-10), which was implemented for mortality coding and classification from death certificates in the U.S. in 1999. The U.S. developed a Clinical Modification (ICD-10-CM) for medical diagnoses based on WHO’s ICD-10. This medical classification list is generated by the World Health Organization (WHO), and is used to help healthcare providers identify and code health conditions.
ICD-10 is required for use by physicians and healthcare providers under the Health Insurance Portability & Accountability Act (HIPAA) and will replace all ICD-9 code sets. There are nearly 5 times as many diagnosis codes in ICD-10-CM than in ICD-9-CM.ICD-10 has alphanumeric categories instead of numeric ones.

What is Alzheimer’s disease?
Alzheimer’s is a progressive neurodegenerative disease that destroys memory, mental function, thinking skills and affects the behavior of those plagued with the disease. In the disease process, the brain cells degenerate and die which leads to dementia/decline in memory and mental function. It is the most common cause of dementia and accounts for over 50% of the cases of diagnoses of dementia. The disease is irreversible and progressive and typically begins in patients during their 60’s.
Alzheimer’s disease and dementia coding
Dementia is an inherent part of the diagnosis of Alzheimer’s disease. The physician does not have to give both a diagnosis of Alzheimer’s disease and dementia in order to report both codes. Per the ICD-10-CM Alphabetic Index, G30.9 would be reported first, followed by F02.81 or F02.80 to show dementia with or without behavioral disturbances. Since the codes F02.80 and F02.81 are in brackets, these are considered a manifestation of the disease and would be sequenced second per the Official Guidelines for Coding and Reporting (1.A.13) or pages 11 & 12 of FY2017.
From the ICD-10-CM Alphabetic Index:
Alzheimer’s G30.9 [F02.81]
- with behavioral disturbance G30.9 [F02.81]
