Inclusion terms

  • Double athetosis (syndrome)
  • Dyskinetic cerebral palsy
  • Dystonic cerebral palsy
  • Vogt disease

Excludes1 inherited from the categories above G80.3

These are not written on G80.3, but they bind it: a note on a category applies to every code beneath it. Billing G80.3 with anything listed here is a denial.

Written on G80 Cerebral palsy

  • hereditary spastic paraplegia (G11.4)

Other codes that can never be billed with G80.3

These codes carry an Excludes1 note pointing at G80.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G80.3 alone.

  • G81Hemiplegia and hemiparesis
  • G82Paraplegia (paraparesis) and quadriplegia (quadriparesis)

Risk adjustment

G80.3 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:

  • HCC 192 Cerebral Palsy, Except Quadriplegic0.314 RAF

Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.

Medicare coverage

G80.3 is named in 39 Medicare coverage policies 39 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
