Code Description

ICD-10 R29.705 is a billable code used to indicate a diagnosis of nihss score 5.

Key Diagnostic Point:

The NIHSS (National Institutes of Health Stroke Scale) score of 5 indicates a moderate stroke severity, reflecting significant neurological impairment. Patients scoring 5 may exhibit symptoms such as unilateral weakness, facial droop, and difficulty with speech or comprehension. This score is derived from a comprehensive assessment of various neurological functions, including consciousness, vision, motor function, and sensory perception. A score of 5 suggests that the patient may have some functional independence but requires close monitoring and potential intervention. Common causes of such a score include ischemic strokes, hemorrhagic strokes, or transient ischemic attacks (TIAs). The clinical context for this score is critical, as it guides treatment decisions and prognostic evaluations. Accurate documentation of the patient's neurological status, including specific deficits and their impact on daily activities, is essential for appropriate coding and management.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation of stroke symptoms
  • Need for precise documentation of neurological deficits
  • Potential overlap with other neurological conditions
  • Interpretation of NIHSS scores can vary among clinicians

Audit Risk Factors

  • Inadequate documentation of NIHSS assessment
  • Failure to specify the clinical context of the score
  • Misinterpretation of the NIHSS score leading to incorrect coding
  • Lack of correlation between documented symptoms and the NIHSS score

Specialty Focus

Internal Medicine

Documentation Requirements

Detailed documentation of neurological examination findings, including specific deficits and their impact on the patient's daily life.

Common Clinical Scenarios

Patients presenting with stroke symptoms in an outpatient or inpatient setting, requiring assessment of neurological function.

Billing Considerations

Consideration of comorbidities that may affect the NIHSS score and overall patient management.

Emergency Medicine

Documentation Requirements

Acute care documentation must include time of onset, NIHSS score, and immediate interventions performed.

Common Clinical Scenarios

Patients arriving at the emergency department with acute stroke symptoms needing rapid assessment and intervention.

Billing Considerations

Timeliness of documentation is critical; ensure that the NIHSS score is recorded promptly to guide treatment decisions.

Coding Guidelines

Inclusion Criteria

Use R29.705 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the NIHSS score is documented accurately and correlates with the clinical findings
  • Use additional codes to specify any underlying conditions contributing to the stroke

Exclusion Criteria

Do NOT use R29.705 When
No specific exclusions found.
