About ICD-9-CM 866.12

866.12 is an ICD-9-CM diagnosis code for injury to kidney with open wound into cavity, laceration. 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 4 ICD-10-CM codes, such as S31.001A (Unspecified open wound of lower back and pelvis with penetration into retroperitoneum, initial encounter), S37.039A (Laceration of unspecified kidney, unspecified degree, initial encounter) and S37.049A (Minor laceration of unspecified kidney, initial encounter). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
