2025 ICD-10-CM code Q89.3
(Active) Effective Date: N/A Congenital malformations, deformations and chromosomal abnormalities - Other congenital malformations 7 Feed
Situs inversus is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions.
The diagnosis of situs inversus is medically necessary as it affects the normal anatomical landmarks and can influence the approach to various medical procedures.It also helps in understanding potential complications associated with this condition.
Diagnosing and managing situs inversus typically falls under the purview of specialists like geneticists, cardiologists, gastroenterologists, and general surgeons, depending on the specific organ systems involved and the presence of any associated complications.
In simple words: Situs inversus is a birth defect where the organs inside the body, like the heart and liver, are on the opposite side compared to most people.So, if your heart is normally on the left, with situs inversus, it would be on the right.
Situs inversus involves the transposition of the internal organs, such as the heart, liver, and stomach, to the opposite side of the body from their normal locations.It includes conditions such as dextrocardia with situs inversus, mirror-image atrial arrangement with situs inversus, situs inversus of the abdomen and/or thorax, and transposition of abdominal and/or thoracic viscera.Dextrocardia without situs inversus is excluded (Q24.0).
Example 1: A newborn infant is found to have dextrocardia during a routine physical exam. Further imaging studies reveal situs inversus totalis, with all major organs mirrored in their positions., A patient undergoing an appendectomy presents with atypical abdominal pain.Intraoperatively, the surgeon discovers situs inversus, with the appendix located on the left side., A patient with situs inversus and no other health issues is being evaluated for an unrelated condition. The code Q89.3 is used to document this anatomical variation, which may be relevant to future treatments or procedures.
Documentation should include imaging studies (e.g., X-ray, CT scan, MRI) confirming the reversed position of organs.Specific details about the affected organs and any associated abnormalities should be clearly noted.
** While situs inversus itself is often asymptomatic, it can be associated with other congenital anomalies, particularly cardiac defects. Therefore, thorough evaluation is crucial.
