G32.8 — Other specified degenerative disorders of nervous system in diseases classified elsewhere

Non-billable headerICD-10-CM

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
amyloidosis cerebral degeneration (E85.-)
cerebral degeneration (due to) hypothyroidism (E00.0-E03.9)
cerebral degeneration (due to) neoplasm (C00-D49)
cerebral degeneration (due to) vitamin B deficiency, except thiamine (E52-E53.-)

Risk adjustment

G32.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

G32.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead G32.8
