Decision Tree for

Follow this step-by-step guide to choose the correct ICD-10 code.

Is the assessment for a specific procedure?

  • Yes

    Is there a complication?

  • No

    Do not code a pre-operative assessment. Code the reason for the encounter.

Documentation Best Practices

Documentation Checklist
  • Pre-op H&P: Date, time, surgeon
  • Patient medical history: Current medications
  • Surgical risk factors documented
  • Review of systems: Pertinent positives/negatives
  • Physical exam: Vital signs, relevant findings

Coding and Audit Risks

Common Risks
  • Unspecified Assessment

    Lack of specific pre-op diagnosis details leads to inaccurate coding and potential underpayment. CDI can clarify.

  • Unlinked Conditions

    Pre-existing conditions impacting surgery risk may be unlinked, affecting DRG assignment and reimbursement. Coding review crucial.

  • Missing History

    Incomplete pre-op history documentation can hinder accurate risk assessment and proper E/M coding. Compliance audits essential.

Mitigation Tips

Best Practices
  • Accurate ICD-10-CM diagnosis coding for pre-op assessments.
  • Thorough pre-op HPI & physical exam documentation improves CDI.
  • HCC coding compliance for pre-op risk adjustment documentation.
  • Clear, concise pre-op assessment details support medical necessity.
  • Timely pre-op documentation submission prevents compliance issues.

Clinical Decision Support

Checklist
  • Verify pre-op H&P: ICD-10-CM Z01.818 documented
  • Confirm surgical risk assessment: ASA score recorded
  • Check labs: CBC, BMP, Coags - CPT documented
  • Review EKG and CXR: Results & interpretations signed

Reimbursement and Quality Metrics

Impact Summary
  • Pre-operative Assessment reimbursement hinges on accurate CPT coding (e.g., 99201-99205) impacting hospital revenue cycle management.
  • Coding quality directly affects pre-operative assessment claim denial rates impacting hospital financial performance metrics.
  • Proper documentation of pre-op assessment supports medical necessity for surgical procedures impacting payer contract compliance.
  • Timely and accurate pre-operative assessment reporting influences hospital quality scores like surgical site infection rates.

Documentation Templates

Pre-operative assessment completed for scheduled surgical procedure.  Patient presents for pre-surgical clearance and optimization.  Medical history reviewed including current medications, allergies, past surgical history, and relevant family history.  Surgical risks assessed and discussed with the patient.  Physical examination performed, including vital signs, cardiovascular, pulmonary, and neurological systems.  Laboratory results reviewed including complete blood count (CBC), comprehensive metabolic panel (CMP), coagulation studies (PT/INR, PTT), and urinalysis.  Electrocardiogram (ECG) obtained and reviewed.  Patient's functional status and American Society of Anesthesiologists (ASA) physical status classification documented.  Anesthesia risks evaluated and discussed, including airway assessment and potential for post-operative nausea and vomiting (PONV).  Pre-operative instructions provided, including NPO guidelines and medication management.  Informed consent obtained for the planned surgical procedure.  Patient deemed optimized for surgery and cleared for the scheduled procedure.  Pre-operative diagnosis consistent with the indication for surgery.  Plan includes continuing current medications as directed and following pre-operative instructions.  Follow-up scheduled post-operatively.  Surgical clearance documentation completed and available in the electronic health record.
