In simple words: This code describes a situation where a person has dementia (which isn't caused by a stroke or Alzheimer's, etc., and hasn't been classified as mild, moderate, or severe) and also experiences anxiety, both due to another medical condition. The other medical condition is diagnosed separately.

This code represents dementia with anxiety, occurring as a result of a known physiological condition other than those specifically classified elsewhere.The underlying physiological condition should be coded first. The unspecified severity indicates the dementia's impact hasn't been graded as mild, moderate, or severe. The associated anxiety should also be addressed.

Example 1: A patient with Huntington's disease (G10) experiences cognitive decline consistent with dementia and also exhibits symptoms of generalized anxiety disorder., A patient with a traumatic brain injury (S06.-) develops dementia and experiences persistent anxiety related to the injury and its consequences., A patient with systemic lupus erythematosus (M32.-) exhibits cognitive decline along with significant anxiety symptoms, potentially related to both the disease process and medications.

Documentation should clearly link the dementia and anxiety to the underlying physiological condition. The diagnostic workup should rule out other potential causes of dementia and anxiety.Severity of dementia (if known) and detailed anxiety symptoms must be documented.The underlying physiological condition must be clearly documented with its corresponding ICD-10-CM code.
