ICD-10 code for shoulder girdle dystocia

The ICD-10-CM code for shoulder girdle dystocia is O66.0 (Obstructed labor due to shoulder dystocia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on O66.0.

Within O66 (other obstructed labor), O66.0 is specifically for obstructed labor due to shoulder dystocia. Related codes cover obstructed labor due to locked twins (O66.1), obstructed labor due to unusually large fetus (O66.2), obstructed labor due to other abnormalities of fetus (O66.3), failed trial of labor (O66.4), attempted application of vacuum extractor and forceps (O66.5), obstructed labor due to other multiple fetuses (O66.6), other specified obstructed labor (O66.8) and obstructed labor, unspecified (O66.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 817 (Other Antepartum Diagnoses with O.R. Procedures with MCC, relative weight 2.0534), DRG 818 (Other Antepartum Diagnoses with O.R. Procedures with CC, relative weight 1.2942), DRG 819 (Other Antepartum Diagnoses with O.R. Procedures without CC/MCC, relative weight 0.7739), DRG 831 (Other Antepartum Diagnoses without O.R. Procedures with MCC, relative weight 1.1558), DRG 832 (Other Antepartum Diagnoses without O.R. Procedures with CC, relative weight 0.7585) and DRG 833 (Other Antepartum Diagnoses without O.R. Procedures without CC/MCC, relative weight 0.5002), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
