About ICD-9-CM 200.50

200.50 is an ICD-9-CM diagnosis code for primary central nervous system lymphoma, unspecified site, extranodal and solid organ sites. 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 C83.39 (Diffuse large B-cell lymphoma, extranodal and solid organ sites), C83.80 (Other non-follicular lymphoma, unspecified site) and C83.89 (Other non-follicular lymphoma, extranodal and solid organ sites). All of these are approximate matches, so review the record to pick the right one.
