G81Hemiplegia and hemiparesis

Non-billable headerICD-10-CM

G81 is a non-billable header ICD-10-CM code for hemiplegia and hemiparesis. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

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

Notes

Additional guidance from the ICD-10-CM tabular list.

  • This category is to be used only when hemiplegia (complete)(incomplete) is reported without further specification, or is stated to be old or longstanding but of unspecified cause. The category is also for use in multiple coding to identify these types of hemiplegia resulting from any cause.

Risk adjustment

G81 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 to one of these instead G81

3 child codes. Green means billable.
