About ICD-9-CM 202.70
202.70 is an ICD-9-CM diagnosis code for peripheral T cell 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 2 ICD-10-CM codes, such as C84.40 (Peripheral T-cell lymphoma, not elsewhere classified, unspecified site) and C84.49 (Peripheral T-cell lymphoma, not elsewhere classified, extranodal and solid organ sites). All of these are approximate matches, so review the record to pick the right one.
