Cerebral palsy (G80) ICD-10-CM
The G80 code range covers cerebral palsy with 8 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- hereditary spastic paraplegia G11.4

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the G80 range.
Ataxic Cerebral Palsy
The least common subtype of cerebral palsy, in which the individual displays hypotonia, a loss of motor coordination, and an intention tremor. Individuals with ataxic cerebral palsy walk very unsteadily, with a wide-based gait.
Athetoid Cerebral Palsy
A subtype of cerebral palsy characterized by involuntary, purposeless writhing movements which affect the hands, feet, arms, and legs; the face and tongue may be affected as well, leading to involuntary grimacing, drooling, dysarthria and difficulty eating.
Cerebral Palsy
A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)
Spastic Diplegia
A type of cerebral palsy characterized by spasticity and hypertonia of the lower extremities bilaterally, particularly the legs, hips, and pelvis; this is the most common (70%) form of cerebral palsy.
Spastic Hemiplegia
A type of spastic cerebral palsy characterized by increased muscle tone of the arm and leg on the same side of the body.
Spastic Quadriplegia
A type of spastic cerebral palsy characterized by increased muscle tone of all four extremities.
About the G80 Code Range
Cerebral palsy involves movement disorders linked to brain injuries from before birth, around birth, or the first few years of life. The disorders do not progressively worsen.
G80 separates spastic forms by the limbs affected: all limbs in G80.0, legs more than arms in G80.1, or one side of the body in G80.2. Separate subdivisions identify athetoid cerebral palsy (G80.3), ataxic cerebral palsy (G80.4), other forms (G80.8), and unspecified cerebral palsy (G80.9).
