About ICD-9-CM 839.30

839.30 is an ICD-9-CM diagnosis code for open dislocation, lumbar vertebra. 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 S31.000A (Unspecified open wound of lower back and pelvis without penetration into retroperitoneum, initial encounter) and S33.101A (Dislocation of unspecified lumbar vertebra, 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.
