About coding eclampsia puerperal
The ICD-10-CM code for eclampsia puerperal is O15.2 (Eclampsia complicating the puerperium).
Within O15 (eclampsia), O15.2 is specifically for eclampsia complicating the puerperium. Related codes cover complicating pregnancy (O15.0), complicating labor (O15.1) and unspecified as to time period (O15.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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.
