About ICD-9-CM 73.91

73.91 is an ICD-9-CM procedure code for external version assisting delivery. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.

The CMS General Equivalence Mappings translate it to 2 ICD-10-PCS codes, such as 10E0XZZ (Delivery of Products of Conception, External Approach) and 10S0XZZ (Reposition Products of Conception, External Approach). 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.
