About ICD-9-CM 203.80

203.80 is an ICD-9-CM diagnosis code for other immunoproliferative neoplasms, without mention of having achieved remission. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.

The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as C88.8 (Other malignant immunoproliferative diseases), C90.20 (Extramedullary plasmacytoma not having achieved remission) and C90.30 (Solitary plasmacytoma not having achieved remission). All of these are approximate matches, so review the record to pick the right one.
