Look to 310 and 331 for Mild Cognitive Impairment
Published on Tue Mar 04, 2008
Question: What diagnoses do carriers usually accept for mild cognitive impairment? Tennessee Subscriber Answer: Codes in the 310 or 331 series might be your best choices. Carriers often accept diagnoses such as: - 310.8 -- Other specified nonpsychotic mental disorders following organic brain damage - 310.9 -- Unspecified nonpsychotic mental disorder following organic brain damage - 331.0 -- Alzheimer's disease - 331.2 -- Senile degeneration of brain - 331.83 -- Mild cognitive impairment, so stated. Note: Always check the specific carrier's local coverage determination to help ensure your diagnosis coding is on track. Medicare, for example, accepts 331.83 for mild cognitive impairment, but Blue Cross/Blue Shield prefers 780.93 (Memory loss). Don't forget: You should never code based on what will get the claim paid. Instead, you should always report the diagnosis code most clearly documented in the physician's notes.
