Diseases of the circulatory system complicating childbirth

This code signifies the presence of a pre-existing or new circulatory system disorder that complicates the peripartum period, including labor, delivery, and the immediate postpartum. It encompasses conditions such as hypertension, heart disease, or vascular disorders that adversely affect the childbirth process.

Apply this code when a patient experiences a circulatory system disease that impacts her pregnancy, labor, or delivery. Documentation should clearly link the circulatory condition to the childbirth event, indicating it as a complicating factor. This code is used in conjunction with a code identifying the specific circulatory disease.

• Always sequence this code after the primary code for the specific circulatory system disease (e.g., essential hypertension, cardiomyopathy).
• Ensure documentation explicitly states the circulatory condition is "complicating" or "due to" childbirth.
• Do not use this code for circulatory conditions that are incidental to childbirth and do not impact the peripartum course.
