Mitigation Strategy

Include explicit statements negating hyperactivity., Use templates that prompt for all required elements.

Impact

Reimbursement: Incorrect coding may lead to reduced reimbursement., Compliance: Non-compliance with coding specificity requirements., Data Quality: Inaccurate healthcare data and statistics.

Mitigation Strategy

Query provider for specificity and use F90.0 if inattentive type is confirmed.

Impact

Risk of audits due to non-specific ADHD coding.

Mitigation Strategy

Ensure detailed documentation of inattentive symptoms and absence of hyperactivity.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

  • Rating scales used

Example Documentation

**History of Present Illness** [Patient] is a [age]-year-old presenting for ADHD evaluation. Caregiver reports: - [Specific symptom] ×[duration] - Impact on [academics/social function] - [Negative hyperactive findings] **Assessment** DSM-5 Criteria Met: ☑ Loses necessary items (e.g., lost 3 jackets this semester) ☑ Avoids sustained mental effort (30min homework takes 2hrs) ☑ [4+ additional symptoms] **Negative Findings** ❌ No impulsivity/hyperactivity per Vanderbilt teacher/parent scales ❌ Normal thyroid function (TSH 2.1 μIU/mL)

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has trouble focusing. Possible ADD.
Good Documentation Example
Exhibits 7/9 DSM-5 inattentive criteria ×8 months: loses school materials daily, avoids sustained mental effort in homework, forgetful in daily activities per parent/teacher reports. No observed fidgeting, excessive talking, or motor restlessness.
