Which MS-DRGs does D65 group to?
D65 sits in MDC 15 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 791Prematurity with Major Problemsmedical
As a secondary diagnosis, D65 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
How is D65 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to D65. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Defibrination (syndrome)
- Fibrinolysis (hemorrhagic) (acquired)
- Proteolysis, pathologic
- Afibrinogenemia › acquired
- Coagulation, intravascular › COVID-19 associated (diffuse) (disseminated)
- Coagulopathy › consumption
- Coagulopathy › intravascular
- Fibrinogenopenia › acquired
- Hypofibrinogenemia › acquired
- Purpura › fulminans, fulminous
- Purpura › gangrenous
- Syndrome › DIC
Excludes1 — never code together
The conditions below can never be reported together with D65 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of D65, but a patient may have both at the same time. When documentation supports it, D65 and the excluded code may both be reported.
Code also
Two codes may be needed to describe the condition fully. Whether D65 is sequenced first depends on the reason for the encounter.
- , if applicable, associated condition
Inclusion terms
Alternative wording in documentation that is classified to D65.
- Afibrinogenemia, acquired
- Consumption coagulopathy
- COVID-19 associated diffuse or disseminated intravascular coagulopathy
- Diffuse or disseminated intravascular coagulation [DIC]
- Fibrinolytic hemorrhage, acquired
- Fibrinolytic purpura
- Purpura fulminans
Excludes2 — not included here — inherited from Chapter 3
The conditions below are not part of D65, but a patient may have both at the same time. When documentation supports it, D65 and the excluded code may both be reported.
- autoimmune disease (systemic) NOS (M35.9)
- certain conditions originating in the perinatal period (P00-P96)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)

- human immunodeficiency virus [HIV] disease (B20)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
How long has D65 existed?
D65 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with D65?
ICD-10-CM declares these codes mutually exclusive with D65 — exactly one of each pair can be correct for a given encounter.
