CodeDescriptionWhen to UseKey Documentation
C91.00Acute lymphoblastic leukemia, not having achieved remissionUse when diagnosing a child with ALL as the primary condition
  • Bone marrow biopsy confirming ALL

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Children's Oncology Group Impairment to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C91.00.

Impact

Clinical: Misrepresentation of patient's condition, Regulatory: Potential audit failure, Financial: Loss of reimbursement

Mitigation Strategy

Use standardized templates, Regular training on documentation standards

Impact

Reimbursement: Potential underpayment due to lack of specificity, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate clinical data representation

Mitigation Strategy

Use G31.84 with supporting documentation

Impact

Risk of incorrect coding without proper documentation

Mitigation Strategy

Ensure all documentation links cognitive issues to treatment

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.
