Neurology & Pain Management Coding Alert

Keep learning new codes to avoid falling behind.

Another issue of Neurology & Pain Management Coding Alert, another round of ICD-10 2023 stories.

The basics: Since the World Health Organization (WHO) debuted its 1,500-plus additions, deletions, and revisions for 2023, coders and providers have been scrambling to get to the bottom of the list, noting which codes they’ll need to start using when ICD-10 2023 takes effect Oct. 1, 2022.

Check out these new additions to ICD-10 2023 that you’ll want to familiarize yourself with before this autumn.

Vascular Dementia Gets Significant Additions

There will be several changes to the F01.- (Vascular dementia) code set in ICD-10 2023.

According to Mayo Clinic, “vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain.”

ICD-10 2023 converted the code F01.51 (Vascular dementia, unspecified severity, with behavioral disturbance) to parent.

Then, ICD-10 added these new codes under the parent:

• F01.511 (Vascular dementia, unspecified severity, with agitation)
• F01.518 (Vascular dementia, unspecified severity, with other behavioral disturbance)

ICD-10 2023 also adds other new codes for vascular dementia, which will ask you to clarify these elements of the patient’s condition:

• Severity
• Presence or absence of other disturbances (psychotic, mood, behavioral, anxiety)

Here’s a sampling of the new codes you’ll find in the F01.- code set in ICD-10 2023. (This is not a complete list.)

• F01.52 (Vascular dementia, unspecified severity, with psychotic disturbance)
• F01.A0 (Vascular dementia, mild, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
• F01.A1 (Vascular dementia, mild, with behavioral disturbance)
• F01.A11 (Vascular dementia, mild, with agitation)
• F01.A2 (Vascular dementia, mild, with psychotic disturbance)
• F01.A3 (Vascular dementia, mild, with mood disturbance)
• F01.A4 (Vascular dementia, mild, with anxiety)
• F01.B0 (Vascular dementia, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
• F01.B1 (Vascular dementia, moderate, with behavioral disturbance)
• F01.B18 (Vascular dementia, moderate, with other behavioral disturbance)
• F01.C1 (Vascular dementia, severe, with behavioral disturbance)
• F01.C2 (Vascular dementia, severe, with psychotic disturbance)
• F01.C3 (Vascular dementia, severe, with mood disturbance)
• F01.C4 (Vascular dementia, severe, with anxiety)

ICD-10 Also Ups Code Count in Dementia in Other Diseases

ICD-10 2023 will also bump up the total number of codes you could use in order to diagnose dementia in other diseases classified elsewhere, which you’ll find under F02.- (Dementia in other diseases classified elsewhere).

Converted to parent: F02.81 (Dementia in other diseases classified elsewhere with behavioral disturbance)

Then, ICD-10 added these new codes under the parent:

• F02.811 (Dementia in other diseases classified elsewhere, unspecified severity, with agitation)
• F02.818 (Dementia in other diseases classified elsewhere, unspecified severity, with other behavioral disturbance)

The new dementia codes don’t stop there, however. ICD-10 2023 introduces new codes that will require you to specify the following elements of the patient’s care:

• Severity
• Presence or absence of other disturbances (psychotic, mood, behavioral, anxiety)

Here’s a sampling of the new codes you’ll find in the F02.- code set in ICD-10 2023. (This is not a complete list.)

• F02.82 (Dementia in other diseases classified elsewhere, unspecified severity, with psychotic disturbance)
• F02.83 (Dementia in other diseases classified elsewhere, unspecified severity, with mood disturbance)
• F02.84 (Dementia in other diseases classified elsewhere, unspecified severity, with anxiety)
• F02.A0 (Dementia in other diseases classified elsewhere, mild, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
• F02.A1 (Dementia in other diseases classified elsewhere, mild, with behavioral disturbance)
• F02.A2 (Dementia in other diseases classified elsewhere, mild, with psychotic disturbance)
• F02.A3 (Dementia in other diseases classified elsewhere, mild, with mood disturbance)
• F02.B0 (Dementia in other diseases classified elsewhere, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
• F02.B18 (Dementia in other diseases classified elsewhere, moderate, with other behavioral disturbance)
• F02.B4 (Dementia in other diseases classified elsewhere, moderate, with anxiety)
• F02.C0 (Dementia in other diseases classified elsewhere, severe, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
• F02.C1 (Dementia in other diseases classified elsewhere, severe, with behavioral disturbance)
• F02.C18 (Dementia in other diseases classified elsewhere, severe, with other behavioral disturbance)
• F02.C3 (Dementia in other diseases classified elsewhere, severe, with mood disturbance)
• F02.C4 (Dementia in other diseases classified elsewhere, severe, with anxiety)

Unspecified Dementia Dx Gets a Little More Specific

There will also be several changes and additions to the F03.- (Unspecified dementia) code set in ICD-10 2023. The new code book will introduce converted to parent code F03.91 (Unspecified dementia with behavioral disturbance).

Then, ICD-10 added these new codes under the new parent:

• F03.911 (Unspecified dementia, unspecified severity, with agitation)
• F03.918 (Unspecified dementia, unspecified severity, with other behavioral disturbance)

The new unspecified dementia codes don’t stop there, however. ICD-10 2023 introduces new codes that will require you to specify the following elements of the patient’s care:

• Severity
• Presence or absence of other disturbances (psychotic, mood, behavioral, anxiety)

Here’s a sampling of the new codes you’ll find in the F03.- code set in ICD-10 2023. (This is not a complete list.)

• F03.92 (Unspecified dementia, unspecified severity, with psychotic disturbance)
• F03.93 (Unspecified dementia, unspecified severity, with mood disturbance)
• F03.94 (Unspecified dementia, unspecified severity, with anxiety)
• F03.A0 (Unspecified dementia, mild, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
• F03.A3 (Unspecified dementia, mild, with mood disturbance)
• F03.A4 (Unspecified dementia, mild, with anxiety)
• F03.B0 (Unspecified dementia, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety)
• F03.B11 (Unspecified dementia, moderate, with agitation)
• F03.B18 (Unspecified dementia, moderate, with other behavioral disturbance)
• F03.B2 (Unspecified dementia, moderate, with psychotic disturbance)
• F03.B3 (Unspecified dementia, moderate, with mood disturbance)
• F03.B4 (Unspecified dementia, moderate, with anxiety)
• F03.C18 (Unspecified dementia, severe, with other behavioral disturbance)
• F03.C2 (Unspecified dementia, severe, with psychotic disturbance)
• F03.C4 (Unspecified dementia, severe, with anxiety).
