About coding diabetes puerperal
The ICD-10-CM code for diabetes puerperal is O24.93 (Unspecified diabetes mellitus in the puerperium). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on O24.93.
Within O24.9 (unspecified diabetes mellitus in pregnancy, childbirth and the puerperium), O24.93 is specifically for unspecified diabetes mellitus in the puerperium. Related codes cover pregnancy (O24.91) and childbirth (O24.92).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 769 (Postpartum and Post Abortion Diagnoses with O.R. Procedures, relative weight 1.6673) and DRG 776 (Postpartum and Post Abortion Diagnoses without O.R. Procedures, relative weight 0.6721), 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.
