What is the ICD-10 code for acute lymphoblastic leukemia?

The ICD-10 code for acute lymphoblastic leukemia is C91.0, with subcategories for remission status: C91.00 (not in remission), C91.01 (in remission), and C91.02 (in relapse).

How is remission status documented for ALL?

Remission status for ALL should be documented with specific criteria such as complete hematologic remission and MRD-negative status, supported by lab results.

Code	Description	When to Use	Key Documentation
C91.00	Acute lymphoblastic leukemia not having achieved remission	Use when the patient has not achieved remission post-treatment.	Bone marrow biopsy showing ≥20% blasts Failed induction therapy Persistent lymphoblasts
C91.01	Acute lymphoblastic leukemia, in remission	Use when the patient is in complete remission.	No detectable blasts on flow cytometry Complete hematologic remission
C91.02	Acute lymphoblastic leukemia, in relapse	Use when the patient experiences a relapse.	Relapse confirmed by bone marrow biopsy Reappearance of CD19+/CD10+ blasts

Documentation & Coding Risks

Avoid these common issues when documenting Lymphoblastic Leukemia.

Omitting genetic marker documentation.

Impact

Clinical: Incomplete clinical picture., Regulatory: Potential non-compliance with coding standards., Financial: Possible denial of claims.

Mitigation

Ensure genetic markers are documented in the patient's record., Review lab reports for genetic findings.

Using C91.0 without specifying remission status.

Impact

Reimbursement: Incorrect coding can lead to improper reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Query for specific remission status: not achieved, in remission, or in relapse.

Remission Status Documentation

Impact

Inadequate documentation of remission status can lead to audit issues.

Mitigation

Implement regular documentation audits and training for clinical staff.
