Unsteady gait is a common clinical complaint that may signal underlying health issues and increase fall risk. Accurate documentation using the R26.81 (Unsteadiness on feet) ICD-10 code is vital for effective treatment planning and reimbursement. This 2025 guide explores the use of R26.81, related codes, and documentation optimization strategies.
Unsteady gait, or gait instability, refers to an abnormal, uncoordinated walking pattern. Patients may exhibit a wobbly or shaky gait, difficulty maintaining balance, or an uneven stride, significantly impacting their quality of life and independence.
Common causes include:
The ICD-10-CM code R26.81 is used for "Unsteadiness on feet." As a symptom code, it describes a general lack of balance during walking without a specific underlying diagnosis.
Accurate coding may require multiple codes to fully describe the patient’s condition. Below are codes related to R26.81:
Include codes for underlying conditions causing unsteady gait, such as:
Thorough documentation supports medical necessity and reimbursement. Here are key tips and examples:
AI-powered tools like S10.AI can simplify documentation in busy clinical settings.
Using R26.81 and related ICD-10 codes accurately is crucial for quality care and reimbursement. Follow the outlined best practices to enhance documentation and consider AI tools like S10.AI’s CRUSH for efficient, accurate SOAP note automation.

What is the difference between ICD-10 codes R26.81, R26.2, and R26.9 for gait abnormalities?
Choosing the correct ICD-10 code is crucial for accurate clinical documentation and billing. Here’s a breakdown of these related but distinct codes: R26.81 (Unsteadiness on feet): This is the most specific code for a patient who presents with a wobbly or shaky gait and has difficulty maintaining balance. It should be used when this is the primary symptom observed. R26.2 (Difficulty walking, not elsewhere classified): This is a more general code for when a patient has trouble walking, but the specific nature of the difficulty isn't defined as unsteadiness. It's used when the issue is less about balance and more about the general act of walking. R26.9 (Unspecified abnormalities of gait and mobility): This code is used when a gait abnormality is present, but the specific type has not been identified or documented. It is considered non-specific and should be avoided for primary billing if a more precise diagnosis is available. For optimal reimbursement and to clearly justify the medical necessity of treatments like physical therapy, it's always best to use the most specific code that accurately describes the patient's condition.
Can I bill R26.81 (Unsteadiness on feet) with other codes, like for a history of falls (R29.6)?
Yes, not only can you, but you often should to provide a complete clinical picture. The ICD-10 guidelines have an "Excludes2" note for R26.81 and R29.6 (Repeated falls), which means the two conditions can occur together and can be coded separately. For example, if a 75-year-old patient presents with an unsteady gait (R26.81) and has fallen three times in the past six months, you would include R29.6 to document the history of falls. This combination strengthens the case for medical necessity for interventions like gait training or physical therapy. Tools like S10.AI's AI scribe can help ensure all relevant diagnoses are captured from the patient encounter and accurately documented in the SOAP note, reducing the risk of claim denials due to incomplete coding.
When should I use a primary diagnosis code, like Parkinson's disease (G20), instead of R26.81?
You should use the primary diagnosis code for the underlying condition causing the unsteady gait, with R26.81 as a secondary diagnosis. For instance, if a patient with a confirmed diagnosis of Parkinson's disease (G20) has an unsteady gait, G20 would be the primary ICD-10 code. R26.81 would then be used as a secondary code to specify the functional limitation (the unsteady gait) that requires intervention. This is important because it shows a more complete and accurate picture of the patient's health status. Manually keeping track of these coding nuances can be challenging. S10.AI can assist by automatically structuring the clinical narrative, making it easier for clinicians and coders to identify the primary and secondary diagnoses based on the documented evidence.
What kind of documentation is needed to support the use of R26.81?
To justify the use of R26.81, your clinical documentation should be detailed and specific. Your SOAP notes should include: Subjective: The patient's own description of their symptoms, such as "feeling wobbly," "losing balance," or "afraid of falling." Objective: Your clinical observations of the patient's gait, including descriptions of their stride, balance, and any assistive devices they use. Mentioning specific findings from examinations like the Timed Up and Go (TUG) test can also be very helpful. Assessment: A clear statement of the diagnosis, such as "Unsteadiness on feet (R26.81)." Plan: The specific interventions you plan to implement, such as physical therapy, balance training, or a referral to a specialist. High-quality, detailed documentation is your best defense against claim denials. AI-powered tools like S10.AI can automatically generate comprehensive SOAP notes from patient conversations, ensuring that the necessary details to support your coding are always included.
How can I improve my practice's coding accuracy and efficiency for gait-related diagnoses?
Improving coding accuracy and efficiency involves a combination of education and technology. Education: Regularly training your clinical and administrative staff on the latest ICD-10-CM coding guidelines for gait-related disorders is essential. Technology: Implementing an AI-powered clinical documentation tool like S10.AI can significantly streamline the process. S10.AI's ambient scribe listens to the natural patient-provider conversation and automatically generates a detailed, accurate, and billable SOAP note. This not only saves clinicians hours of administrative work but also helps ensure that the documentation fully supports the selected ICD-10 codes, leading to improved reimbursement and fewer denials. By leveraging AI, your practice can enhance the quality of your clinical documentation, improve coding accuracy, and free up valuable time to focus on what matters most: your patients.
