R26.89 diagnosis code: Other abnormalities of gait and mobility

The R26.89 diagnosis code is a medical code under the International Classification of Diseases, 10th Revision (ICD-10). It indicates the presence of other abnormalities of gait and mobility that cannot be classified under any other code in the ICD-10 system.

This code may describe various conditions, such as difficulty with walking, loss of balance, problems with coordination, weakness, stiffness, or other issues that affect a person's ability to move around normally.

Healthcare providers who use this code, such as physical therapists, podiatrists, orthopedists, and neurologists, may have to use additional codes to provide a more specific diagnosis or indicate the underlying cause of the gait or mobility abnormality. A healthcare provider or medical coder can provide more information on the appropriate use of this code for more accurate coding.

Is R26.89 billable?

Yes, this ICD-10-CM code is billable.

Clinical information

Various neurological, musculoskeletal, and cardiovascular conditions can cause gait abnormalities. Some of the common conditions that may result in gait abnormalities include:

  • Stroke or other neurological disorders
  • Parkinson's disease, postural instability gait disorder, or other movement disorders
  • Multiple sclerosis
  • Spinal cord injury or disease
  • Arthritis or other joint problems
  • Peripheral neuropathy or nerve damage
  • Trauma or injury to the legs or feet
  • Congenital disorders or developmental delays

The symptoms of gait abnormalities can vary widely depending on the underlying cause. Some people may experience difficulty with balance or coordination, while others may have weakness or stiffness in their legs, making walking difficult. In some cases, a patient's gait abnormalities may be temporary and can be resolved with treatment, while in other cases, they may be chronic and require ongoing management.

Treatment for gait abnormalities may include physical therapy, medication, assistive devices such as braces or canes, or surgery in some cases. For improved patient outcomes, a specific treatment approach may be needed based on the underlying cause of the gait abnormality and the patient's needs.

Synonyms include

  • Multifactorial gait disorder
  • Weakness gait disorder
  • Unsteady gait
  • Weakness gait disturbance
  • Ambulatory dysfunction
