About ICD-9-CM 663.31

663.31 is an ICD-9-CM diagnosis code for other and unspecified cord entanglement, without mention of compression, complicating labor and delivery, delivered, with or without mention of antepartum condition. 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 3 ICD-10-CM codes, such as O69.81X0 (Labor and delivery complicated by cord around neck, without compression, not applicable or unspecified), O69.82X0 (Labor and delivery complicated by other cord entanglement, without compression, not applicable or unspecified) and O69.89X0 (Labor and delivery complicated by other cord complications, not applicable or unspecified). All of these are approximate matches, so review the record to pick the right one.
