About ICD-9-CM 200.55

200.55 is an ICD-9-CM diagnosis code for primary central nervous system lymphoma, lymph nodes of inguinal region and lower limb. 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 2 ICD-10-CM codes, such as C83.35 (Diffuse large B-cell lymphoma, lymph nodes of inguinal region and lower limb) and C83.85 (Other non-follicular lymphoma, lymph nodes of inguinal region and lower limb). All of these are approximate matches, so review the record to pick the right one.
