Implication

Validation study reveals ICD-10-CM intracranial injury codes reliably identify traumatic brain injury in hospitalized patients, highlighting strong diagnostic accuracy for surveillance.

Key Points

Assess the positive predictive value of ICD-10-CM codes included in the CDC's 2016 traumatic brain injury surveillance definition for identifying confirmed inpatient cases.
Reviewed a random sample of N=196 inpatient records containing ICD-10-CM traumatic brain injury codes from a 1,160-bed health system.
Calculated positive predictive values with 95% confidence intervals against clinician-documented traumatic brain injury diagnoses.
The overall positive predictive value was 74% [95% CI: 67.9%, 80.1%] for codes in any diagnostic position and 91.5% [95% CI: 86.2%, 96.8%] when documented as the principal diagnosis.
Intracranial injury codes (S06) yielded a positive predictive value of 80.2% [95% CI: 74.3%, 86.1%] across any position and 96.9% [95% CI: 93.3%, 100%] as the principal diagnosis.
Skull fracture codes (S02.0-.1) lacking concurrent S06 codes demonstrated a positive predictive value of 15.8% [95% CI: 0%, 33.2%] in any diagnostic field.
