0.000What This Code Means
This is a type of aggressive blood cancer (lymphoma) that affects immune cells and does not have a specific genetic marker (ALK-negative), and the patient is currently in remission, meaning the cancer is not actively growing or detectable.
Coding Tips
- •Ensure documentation clearly states 'in remission' status, as this affects staging and prognosis coding; remission status must be explicitly documented by the physician
- •Verify the ALK-negative status is confirmed through pathology or molecular testing results, as this distinguishes it from ALK-positive anaplastic large cell lymphoma (C84.7A)
Clinical Significance
Anaplastic large cell lymphoma, ALK-negative, in remission indicates the patient has achieved disease control from this aggressive lymphoma. ALK-negative ALCL has lower remission rates than ALK-positive disease, making this a notable clinical milestone. Ongoing surveillance is essential due to the higher relapse risk associated with ALK-negative status.
Documentation Requirements
- ✓Original pathology confirming ALCL ALK-negative
- ✓Oncologist documentation explicitly stating remission status
- ✓Most recent imaging confirming no active disease
- ✓Surveillance plan documented
- ✓Treatment history including regimen received
Commonly Confused Codes
C84.6A — ALCL ALK-positive, in remission: Different ALK status; verify original pathologyC84.70 — ALCL ALK-negative, unspecified (active): Active disease, not remissionZ85.79 — Personal history of malignant neoplasm of lymphoid tissue: History code implies resolved disease; premature during active remission monitoringC84.4A — PTCL-NOS, in remission: Different lymphoma subtype
