Code Description

ICD-10 R29.717 is a billable code used to indicate a diagnosis of nihss score 17.

Key Diagnostic Point:

The NIHSS (National Institutes of Health Stroke Scale) score of 17 indicates a severe level of neurological impairment, typically associated with significant stroke-related deficits. This score is derived from a comprehensive assessment of various neurological functions, including consciousness, language, motor skills, sensory perception, and visual fields. A score of 17 suggests that the patient may exhibit profound weakness, altered consciousness, and significant difficulties in communication and comprehension. Common symptoms may include hemiparesis, aphasia, and neglect. The NIHSS is crucial for determining the severity of a stroke, guiding treatment decisions, and predicting patient outcomes. It is essential for healthcare providers to accurately assess and document the NIHSS score to ensure appropriate coding and billing, as well as to facilitate effective communication among the care team.

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
  • Importance of accurate scoring for treatment decisions

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

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed documentation of neurological examination findings, including specific deficits and the context of the NIHSS score.

Common Clinical Scenarios

Patients presenting with acute stroke symptoms, requiring comprehensive neurological evaluation.

Billing Considerations

Consideration of comorbidities that may affect neurological function and NIHSS scoring.

Emergency Medicine

Documentation Requirements

Immediate and thorough documentation of the NIHSS score upon patient presentation, including time of onset and any interventions initiated.

Common Clinical Scenarios

Acute stroke presentations requiring rapid assessment and intervention.

Billing Considerations

Timeliness of documentation is critical for treatment eligibility and coding accuracy.

Coding Guidelines

Inclusion Criteria

Use R29.717 When
  • According to ICD
  • CM guidelines, the NIHSS score should be documented clearly in the medical record, with specific attention to the neurological deficits assessed
  • The score should correlate with the clinical findings and be supported by the physician's notes

Exclusion Criteria

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of stroke-related symptoms and severity, enhancing the ability to capture the complexity of neurological impairments such as those reflected in the NIHSS score.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of stroke-related symptoms and severity, enhancing the ability to capture the complexity of neurological impairments such as those reflected in the NIHSS score.

Reimbursement & Billing Impact
