Range Overview

high priority

The ICD-10 code range G80-G83 is dedicated to cerebral palsy and other paralytic syndromes. These codes cover a variety of conditions that result in paralysis, including cerebral palsy, hemiplegia, paraplegia, and quadriplegia. The codes are used to document the specific type of paralysis, the body part affected, and the cause of the condition, if known. These codes are essential for accurate medical documentation and billing, and for tracking and studying these conditions on a population level.

Key Usage Points:

  • Always code the specific type of paralysis when known.
  • Use additional codes to document the cause of the paralysis, if known.
  • When the affected body part is not specified, use the unspecified code.
  • Use the appropriate code for transient paralysis conditions.
  • For congenital paralysis conditions, use the appropriate code from the Q00-Q99 range.

Coding Guidelines

When to Use:

  • When a patient is diagnosed with cerebral palsy.
  • When a patient has a paralytic syndrome due to a stroke.
  • When a patient has a paralytic syndrome due to a spinal cord injury.
  • When a patient has a paralytic syndrome due to a brain injury.
  • When a patient has a paralytic syndrome due to a disease such as multiple sclerosis.

When NOT to Use:

  • When a patient has temporary weakness but not true paralysis.
  • When a patient has a condition that causes muscle weakness, such as muscular dystrophy, but not paralysis.
  • When a patient has a condition that affects the nerves, such as neuropathy, but not the muscles.
  • When a patient has a condition that affects the muscles, such as myopathy, but not the nerves.

Code Exclusions

Always verify the patient's specific condition and symptoms before coding.

Documentation Requirements

When documenting a diagnosis of cerebral palsy or another paralytic syndrome, it is essential to include the specific type of paralysis, the body part affected, and the cause of the condition, if known. The documentation should also include the patient's symptoms, the results of any diagnostic tests, and the treatment plan.

Clinical Information:

  • Specific type of paralysis
  • Body part affected
  • Cause of the condition, if known
  • Patient's symptoms
  • Results of diagnostic tests

Supporting Evidence:

  • Medical history
  • Physical examination findings
  • Imaging studies
  • Laboratory test results
Good Documentation Example:

Patient diagnosed with left-sided hemiplegia due to a stroke. Symptoms include weakness and loss of sensation on the left side of the body. CT scan shows a right-sided cerebral infarct.

Poor Documentation Example:

Patient has weakness on the left side.

Common Documentation Errors:

  • Not specifying the type of paralysis
  • Not specifying the body part affected
  • Not documenting the cause of the condition
  • Not including the patient's symptoms or the results of diagnostic tests

Coding Complexity

Medium
Complexity Rating

Coding for cerebral palsy and other paralytic syndromes can be complex due to the need to accurately identify the specific type of paralysis, the body part affected, and the cause of the condition. In addition, it is important to understand the difference between muscle weakness and true paralysis, as conditions that cause muscle weakness are coded elsewhere.

Key Factors:
  • Determining the specific type of paralysis
  • Identifying the body part affected
  • Determining the cause of the condition
  • Understanding the difference between muscle weakness and true paralysis

Specialty Focus

The G80-G83 range is primarily used by neurologists, physiatrists, and pediatricians. These specialists diagnose and treat patients with cerebral palsy and other paralytic syndromes.

Primary Specialties:
Neurology
40%
Physical Medicine and Rehabilitation
30%
Pediatrics

Clinical Scenarios:
  • A child with spastic cerebral palsy due to a birth injury.
  • An adult with left-sided hemiplegia due to a stroke.
  • A patient with paraplegia due to a spinal cord injury.
  • A patient with quadriplegia due to a progressive neurological disease such as multiple sclerosis.

Frequently Asked Questions

How do I code for a patient with cerebral palsy who also has epilepsy?

You would use a code from the G80 range for the cerebral palsy and a code from the G40 range for the epilepsy. Always code each condition separately.
