R26.9 - Unspecified abnormalities of gait and mobility: This is meant to be used if the patient is confirmed to have abnormalities of gait and mobility, but it's unspecified as to what the specific abnormalities are.
R26.81 - Unsteadiness on feet: This is meant to be used if the patient is confirmed to have unsteadiness whenever they're on their feet.
R26.1 - Paralytic gait: This is meant to be used if the patient is confirmed to have an abnormal walking pattern due to paralysis.
R26.0 - Ataxic gait: This is meant to be used if a patient is confirmed to have an abnormal walking pattern due to a failure of muscle coordination.
R26.89 - Other abnormalities of gait and mobility: This is meant to be used if a patient is confirmed to have a gait and mobility abnormality, but there are no specific ICD codes for it.

Which gait abnormalities ICD codes are billable?

All listed codes above are billable and can be used to designate a patient for reimbursement purposes.

Clinical information

Gait abnormalities refer to atypical walking patterns.
It is common for young children to exhibit temporary gait abnormalities during their growth and development stages as they learn to walk.
While parents may be concerned about their children's unusual walking patterns, it is essential to note that gait abnormalities are often a normal part of physical development.
In most cases, children naturally outgrow these abnormalities without requiring medical intervention.
Gait abnormalities tend to be more prevalent as individuals age.
Approximately 15% of people develop a gait abnormality by age 60, while over 80% of individuals aged 85 and above experience a gait abnormality.
In contrast, children are less likely to have gait abnormalities unless they have an underlying health condition or have suffered an injury.
Gait training can help address gait abnormalities, but sometimes not to the fullest extent.
