Documentation Best Practices

Documentation Checklist
  • Long-term current drug therapy diagnosis
  • ICD-10-CM Z79.89 Other long term drug therapy
  • Document drug name, dosage, frequency, and route
  • Specify duration of therapy and indication
  • Include patient response and any adverse effects

Coding and Audit Risks

Common Risks
  • Unspecified Drug

    Coding Z79.898, Other long term current drug therapy, without specifying the drug creates audit risks and impacts reimbursement.

  • Unconfirmed Diagnosis

    Lack of proper documentation confirming long-term drug therapy can lead to coding errors and compliance issues. CDI review needed.

  • Incorrect Z Code Use

    Using Z79.898 when a more specific Z code for the medication exists leads to inaccurate reporting and potential denials. Review guidelines.

Mitigation Tips

Best Practices
  • Document drug start date, indication, and duration for accurate coding.
  • Regularly review long-term drug therapy necessity for optimal patient care and compliance.
  • Query physicians for clarification on unspecified diagnoses related to drug therapy.
  • Ensure medication documentation aligns with ICD-10-CM and RxNorm coding guidelines.
  • Educate CDI staff on proper coding of chronic conditions requiring long-term medication.

Clinical Decision Support

Checklist
  • Verify medication active > 3 months documented
  • Confirm medication aligns with chronic condition
  • Review patient reported medication adherence
  • Check for documented long-term therapeutic intent

Reimbursement and Quality Metrics

Impact Summary
  • Long-term drug therapy reimbursement impacts coding accuracy, impacting hospital revenue cycle management and requiring correct ICD-10-CM Z79.89 and appropriate supporting documentation for optimal claims processing.
  • Quality metrics for long-term drug therapy focus on medication adherence and potential adverse drug events, impacting hospital quality reporting and requiring accurate documentation and coding for performance measurement.
  • Accurate coding and documentation of long-term drug therapy directly impact hospital reimbursement, affecting case mix index and potentially triggering audits. Proper coding maximizes payment and minimizes denials.
  • Hospital reporting on long-term drug therapy relies on accurate diagnosis coding for patient risk stratification, influencing quality improvement initiatives and resource allocation for chronic disease management.
