Neurologists showed substantial agreement when coding stroke diagnoses using ICD-9-CM codes. However, specific training did not improve coding accuracy for stroke or cerebral artery occlusion.

Area of Science:

  • Neurology
  • Medical Informatics
  • Health Services Research

Background:

  • Accurate coding of stroke diagnoses is crucial for epidemiological studies and healthcare management.
  • The International Classification of Diseases 9th Revision - Clinical Modification (ICD-9-CM) is widely used for disease classification.
  • Inter-coder reliability in stroke coding among neurologists requires evaluation.

Purpose of the Study:

  • To assess the agreement among neurologists when coding stroke using ICD-9-CM codes.
  • To compare coding agreement across different levels of neurologist expertise.
  • To determine if specialized ICD-coding training enhances reliability.

Main Methods:

  • Four neurology residents, four general neurologists, and four expert neurologists coded clinical records of 53 patients.

  • Patient records included stroke, transient ischemic attack (TIA), and other neurological conditions.
  • Inter-coder agreement was quantified using the kappa statistic, analyzing primary (PDx) and secondary diagnoses (SDx).

    • Main Results:

    • Overall kappa for ICD-9-CM codes 430-438 was substantial (0.77 for PDx, 0.82 for PDx+SDx).
    • Agreement was higher for intracerebral hemorrhage (ICD-9-CM 431) (0.83-0.88) than for occlusion of cerebral arteries (ICD-9-CM 434) (0.48-0.51).
    • Specialized ICD-coding training did not significantly improve inter-coder agreement.

    Conclusions:

    • Neurologists demonstrate substantial agreement in coding stroke diagnoses (ICD-9-CM 430-438).
    • Coding reliability varies by specific diagnosis, with intracerebral hemorrhage being more consistent than cerebral artery occlusion.
    • Current ICD-coding training approaches may not be sufficient to enhance inter-coder reliability for stroke diagnoses.
