Wiki Elevated Serum Free Light Chains

[sorcha48]

I am auditing an Oncology Clinic visit. The patient had an lab come back showing elevated light chains. The coder has the primary dx of c90.00 (multiple myeloma that has not achieved remission)

The Oncologist indicates there is no evidence of malignancy or a plasma cell dycrasia on a test of the bone marrow.

I believe coding C90.00 is incorrect and would be R74.8: Abnormal levels of other serum enzymes.

Can I get some assistance?

Elevated light chains is a symptom/lab result. It's not a definitive diagnosis. With the oncologist also indicating no evidence of malignancy, I would definitely not code it as MM not in remission. Multiple myeloma is a malignant diagnosis.

Thank you. I was thinking the same thing. But then I over thought it.
