2025 ICD-10-CM code O28.8
Other abnormal findings on antenatal screening of mother.
The medical necessity of using this code is determined by the clinical significance of the abnormal finding.The documentation should support the need for further investigation or management based on the abnormal result.
The healthcare provider ordering and interpreting the antenatal screening tests is responsible for documenting the abnormal findings and using this code.
- O00-O9A Pregnancy, childbirth and the puerperium
- Other maternal disorders predominantly related to pregnancy (O20-O29)
In simple words: This code indicates that an unusual result was found during a routine pregnancy screening test. It is used when the specific abnormality doesn't have its own code.
This code is used to report other abnormal findings on antenatal screening of the mother that are not classified elsewhere.
Example 1: A pregnant woman undergoes a routine urine test as part of her antenatal screening. The test reveals an unusual protein level not high enough to be classified as proteinuria, but still considered abnormal. This would be coded as O28.8., During a routine ultrasound, a pregnant woman is found to have slightly elevated amniotic fluid levels but not enough to diagnose polyhydramnios. This could be coded as O28.8., A pregnant woman's blood test shows mildly elevated liver enzymes, but the levels are not indicative of a specific liver condition. In this case, O28.8 might be used to document this non-specific abnormal finding.
Documentation should specify the type of antenatal screening performed, the specific abnormal finding, and the date of the finding. Any associated symptoms or further investigations should also be documented.
** This code is for use in conjunction with codes from category Z3A, Weeks of gestation, to specify the pregnancy week if known.
