0.000What This Code Means
A type of blood cancer (leukemia) of unknown cell type that is currently in remission, meaning the cancer is not detectable or has responded well to treatment.
Coding Tips
- •Only assign this code when documentation explicitly states the patient is in remission
- •Remission status must be clearly documented in the medical record to differentiate from C95.90
Clinical Significance
Leukemia, unspecified, in remission represents the uncommon scenario where a leukemia achieved remission without ever having its specific type determined. This may occur when treatment was initiated empirically, the patient transferred care with incomplete records, or early records were lost.
Documentation Requirements
- ✓Documentation must confirm remission status despite the inability to specify the leukemia type.
- ✓The reason for the lack of specificity should be explained.
- ✓Remission evidence such as normalized blood counts and bone marrow findings should be recorded, along with the ongoing surveillance plan.
Commonly Confused Codes
C95.01 (acute leukemia, unspecified, in remission) and C95.11 (chronic leukemia, unspecified, in remission) offer more specificity if the acute/chronic nature is known.Z85.6 (personal history of leukemia) should not replace this active diagnosis code during surveillance.Any specific leukemia code in remission is preferred.
