Cerebral Palsy: Documenting Motor Type, Severity, and Coding Impact
Definition: Cerebral palsy (CP) describes a group of heterogeneous conditions that have lifelong impact on motor function, muscle tone, posture, and movement. This is due to the improper development of the fetal or infant brain. Motor function deficits can range in severity and are commonly accompanied by altered sensation, intellectual disability, seizures, and musculoskeletal complications.
Clinical Features and Indicators of Cerebral Palsy
Common Motor Function Features:
- Muscle spasticity
- Hyperreflexia
- Clonus
- Hypotonia
- Ataxia
Common Clinical Indicators:
- Abnormalities in motor activity and tone
- Delay in meeting developmental motor milestones
- Abnormal developmental reflexes
- Feeding difficulty
- Growth failure
- Epilepsy
Cerebral Palsy Motor Phenotypes
Common motor phenotypes:
- Spastic CP - Most common pattern of motor impairment, accounting for up to 85 percent of individuals with CP. These patients have clinical features of an upper motor neuron syndrome, including muscle hypertonia, hyperreflexia, extensor plantar responses, and clonus.
- Dyskinetic CP - Indicates that dyskinesia such as dystonia or choreoathetosis (e.g., involuntary twitching) is the predominant pattern of abnormal tone.
- Ataxic CP - Characterized by uncoordinated movements and speech, usually associated with widespread disorder of motor function. This type is rare.
ICD-10-CM Coding for Cerebral Palsy
| Condition | Code | SOI | CC/MCC/OSP |
|---|---|---|---|
| Spastic diplegic cerebral palsy | G80.1 | 1 | CC/OSP |
| Spastic hemiplegic cerebral palsy | G80.2 | 1 | CC/OSP |
| Spastic athetoid cerebral palsy | G80.3 | 2 | CC/OSP |
| Spastic quadriplegic cerebral palsy | G80.0 | 2 | MCC |
CDI Documentation and Query Considerations
Thoughts for the CDI Professional
- Intellectual disability is common in children with CP, 40-65%.
- Documentation should indicate the degree of weakness or paralysis associated with CP and any intellectual disability with severity specified.
Sample CDI Query for Cerebral Palsy Specificity
Query Example:
Dr. _________
This patient has documentation and findings for cerebral palsy in the H&P from x/x.
Based on review of the clinical indicators presented, can this information be further specified? For example:
- Spastic hemiplegic cerebral palsy
- Other explanation of clinical findings (please specificity)
Additional supporting information from patient’s record:
Clinical Indicators:
- Physical Exam notes left sided spasticity and increased tone and thin left upper extremity likely related to limitation of use.
Risk Factors:
- Patient with neonatal asphyxia at birth
Monitoring/Evaluation and/or Treatment:
- Continuation of PTA Baclofen
- Recent injection of Botulinum toxin
- PT/OT consult ordered

Please use your independent professional judgment when responding. A question does not imply that a particular diagnosis is expected. Please update your last progress note and/or discharge summary to include the relevant diagnosis.
This query will become part of the patient’s permanent medical record.
