R27.9

Unspecified lack of coordination

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R27.9 is a billable code used to indicate a diagnosis of unspecified lack of coordination.

Key Diagnostic Point:

Unspecified lack of coordination refers to a condition where an individual experiences difficulties in coordinating movements, which may manifest as clumsiness, unsteadiness, or difficulty in performing tasks that require fine motor skills. This symptom can arise from various underlying conditions affecting the nervous system, musculoskeletal system, or even metabolic disorders. Patients may present with a range of symptoms including tremors, difficulty walking, or challenges in performing daily activities. The lack of coordination may be acute or chronic and can significantly impact a patient's quality of life. It is essential to conduct a thorough clinical evaluation to determine the underlying cause, which may include neurological assessments, imaging studies, and laboratory tests. The unspecified nature of this code indicates that the exact cause of the lack of coordination has not been determined, necessitating further investigation and documentation to guide treatment and management.

Internal Medicine

Documentation Requirements

Detailed patient history, physical examination findings, and any relevant lab results must be documented to support the diagnosis.

Common Clinical Scenarios

Patients presenting with unexplained clumsiness or difficulty in performing daily activities, often requiring a multidisciplinary approach for diagnosis.

Billing Considerations

Consideration of comorbidities such as diabetes or hypertension that may contribute to neurological symptoms.

Emergency Medicine

Documentation Requirements

Acute care documentation must include a rapid assessment of neurological status and any immediate interventions taken.

Common Clinical Scenarios

Patients presenting with sudden onset of lack of coordination, potentially indicating a stroke or other acute neurological event.

Billing Considerations

Rapid identification of life-threatening conditions is crucial; documentation should reflect the urgency of the situation.
