Hydrops fetalis due to hemolytic disease (P56)

ICD-10 code P56 covers cases of hydrops fetalis due to hemolytic disease, a serious condition where excess fluid builds up in a fetus because of red blood cell destruction. This section is used to specify the type and cause of hemolytic disease leading to hydrops fetalis.

The main ICD-10 codes in this category help healthcare providers and coders identify the underlying cause precisely. For example, P56.0 is the code assigned when hydrops fetalis results from isoimmunization, a condition where the mother's immune system attacks fetal red blood cells, sometimes referred to simply as "hydrops fetalis due to isoimmunization." Other codes like P56.9, P56.90, and P56.99 distinguish between unspecified or other types of hemolytic diseases causing the fluid buildup. Correctly using these codes ensures clear documentation of cases involving hemolytic jaundice and perinatal complications. Thus, the ICD-10 code for hydrops fetalis related to hemolytic disease is essential for accurately capturing the cause and guiding proper medical management and reporting.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Hydrops Fetalis

Abnormal accumulation of serous fluid in two or more fetal compartments, such as SKIN; PLEURA; PERICARDIUM; PLACENTA; PERITONEUM; AMNIOTIC FLUID. General fetal EDEMA may be of non-immunologic origin, or of immunologic origin as in the case of ERYTHROBLASTOSIS FETALIS.
