Documentation Best Practices

Documentation Checklist
  • History of drug use: type, frequency, amount, route
  • Document specific drug names, including OTC and illicit
  • Dates of first and last use for each drug
  • Prior treatment for substance use disorder if any
  • Impact of drug use on patients health social life

Coding and Audit Risks

Common Risks
  • Unspecified Drug Use

    Coding Z72.0 without specific drug details leads to inaccurate data, impacting quality reporting and reimbursement.

  • Past vs. Present Use

    Confusing past drug use (Z86.4) with active addiction (F1x.2x) creates compliance and patient safety risks.

  • Drug Use Documentation

    Insufficient clinical documentation to support drug use diagnosis causes coding errors and potential denials.

Mitigation Tips

Best Practices
  • Document specific drug names, routes, frequency, and last use.
  • Distinguish past use, recent use, and active addiction.
  • Use standardized terminology (SNOMED CT, ICD-10) for drug use.
  • Query physician for clarification if documentation is vague.
  • Correlate drug history with physical exam and lab results.

Clinical Decision Support

Checklist
  • Verify documented drug use details: type, route, frequency, duration.
  • Check ICD-10 Z codes (Z72.0, Z86.4) for personal history of drug use.
  • Screen for related diagnoses: substance use disorder, overdose, withdrawal.
  • Review patient history for social determinants of health impacting drug use.
  • Assess for current drug use and document appropriately using ICD-10 codes.

Reimbursement and Quality Metrics

Impact Summary
  • History of Drug Use coding impacts reimbursement through accurate risk adjustment and HCC capture.
  • Proper coding of drug history affects quality metrics related to substance use screening and intervention rates.
  • Accurate drug use documentation and coding improves hospital reporting on patient populations and resource allocation.
  • Specificity in drug history coding (e.g., opioid use, cannabis use) enhances data analysis for public health initiatives.
