Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the N98 range.
Ovarian Hyperstimulation Syndrome
A complication of OVULATION INDUCTION in infertility treatment. It is graded by the severity of symptoms which include OVARY enlargement, multiple OVARIAN FOLLICLES; OVARIAN CYSTS; ASCITES; and generalized EDEMA. The full-blown syndrome may lead to RENAL FAILURE, respiratory distress, and even DEATH. Increased capillary permeability is caused by the vasoactive substances, such as VASCULAR ENDOTHELIAL GROWTH FACTORS, secreted by the overly-stimulated OVARIES.
About the N98 Code Range
ICD-10 code N98 covers complications arising specifically from artificial fertilization procedures. This section is used to document and code various medical issues encountered during or after treatments such as artificial insemination, in vitro fertilization, and embryo transfer.
The ICD-10 code for complications associated with artificial fertilization includes detailed categories addressing different types of problems. For example, N98.0 codes infections linked to artificial insemination, while N98.1 describes ovarian hyperstimulation syndrome, a condition involving excessive ovarian response during fertility treatments. Codes N98.2 and N98.3 relate to complications with embryo implantation and transfer, respectively, capturing failures or adverse effects during these specific steps. Additionally, N98.8 includes other less common complications, such as venous thrombosis or vaginal adenosis after assisted fertilization. When a more precise diagnosis cannot be determined, N98.9 serves as a catch-all for unspecified complications related to medically assisted reproduction. Including common terms like "disorder due to medically assisted reproduction" and "complication of artificial insemination" helps accurately identify the correct ICD-10 code for the documented issue.
