Acquired atrophy of fallopian tube, unspecified side

This diagnosis code signifies the pathological reduction in size or wasting away of a fallopian tube that developed after birth, without specifying whether it affects the left or right tube. This atrophy can result from various factors such as chronic inflammation, vascular insufficiency, or hormonal changes, leading to impaired tubal function.

Assign this code when documentation clearly indicates acquired atrophy of a fallopian tube but does not specify the laterality (left or right). This is appropriate when imaging reports (e.g., ultrasound, MRI) or surgical findings describe tubal atrophy without further detail on the affected side.

• Avoid using this code if the documentation specifies laterality; instead, use N83.321 (right) or N83.322 (left).
• Ensure the documentation differentiates between congenital absence/hypoplasia (Q50.5) and acquired atrophy.
• Query the provider if laterality is not documented, as more specific codes are available.
