D65Disseminated intravascular coagulation [defibrination syndrome]

D65 is the ICD-10-CM diagnosis code for disseminated intravascular coagulation [defibrination syndrome]. It belongs to block D65-D69 (coagulation defects, purpura and other hemorrhagic conditions) and chapter 3 (diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Don't report D65 together with the conditions in its Excludes1 note: disseminated intravascular coagulation (complicating):, in newborn (P60) and pregnancy, childbirth and the puerperium (O45.0, O46.0, O67.0, O72.3).

The conditions in its Excludes2 note aren't part of D65, but may be coded alongside it if the patient has both: disseminated intravascular coagulation (complicating): and abortion or ectopic or molar pregnancy (O00-O07, O08.1).

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 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195) and DRG 813 (Coagulation Disorders, relative weight 1.5257), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 16 (Diseases and Disorders of the Blood and Blood Forming Organs and Immunological Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 286.6 (defibrination syndrome).
