KA05.6

ICD-11 MMS 2026-01

Fetus or newborn affected by abnormal uterine contractions

Description

Abnormal uterine contractions can either be hypertonic or hypotonic. Hypertonic contractions are ones that occur more frequently and are marked by an increase in resting tone to more than 15 mm Hg. Hypotonic contractions are ones where the number of contractions is unusually low, the resting tone of the uterus is less than 10 mm Hg, and the strength of contractions is consistently < 26 mm Hg.

Coding note from above levels

These codes are for use when the listed maternal conditions are specified as the cause of confirmed morbidity or potential morbidity which have their origin in the perinatal period (before birth through the first 28 days after birth). Use additional code to identify the condition in the fetus or newborn.

Conditions arising in the perinatal period, even though death or morbidity occurs later, should, as far as possible, be coded to chapter 19, which takes precedence over chapters containing codes for diseases by their anatomical site. For children less than 28 days old, assume that a reported condition developed in the perinatal period, unless the duration is stated and the onset was after the first completed week of life.
