N97.2 Female infertility of uterine origin

Name of the Condition

• Female Infertility of Uterine Origin
• ICD-10 Code: N97.2

Summary

Female infertility of uterine origin refers to the inability to conceive due to abnormalities or conditions affecting the uterus. This may involve structural issues, such as fibroids, polyps, or congenital malformations, or functional problems that impair implantation or support pregnancy. The condition is a subset of female infertility, focusing specifically on uterine factors as the primary cause.

Causes

Uterine infertility can result from congenital anomalies (e.g., uterine septum, bicornuate uterus), acquired structural changes (e.g., fibroids, adenomyosis, or scar tissue from prior surgeries), or conditions like Asherman syndrome (intrauterine adhesions). Endometrial inflammation, infections, or hormonal imbalances affecting the uterine lining may also contribute. In some cases, the cause remains unexplained despite evaluation.

Risk Factors

• Prior uterine surgery: Procedures like dilation and curettage (D&C) or cesarean sections.
• Chronic uterine conditions: Fibroids, polyps, or adenomyosis.
• Infections: Pelvic inflammatory disease (PID) or endometritis.
• Hormonal disorders: Conditions affecting endometrial development.
• Genetic factors: Congenital uterine abnormalities.

Symptoms

• Difficulty conceiving or recurrent pregnancy loss.
• Abnormal menstrual bleeding (e.g., heavy, irregular, or painful periods).
• Pelvic pain or discomfort.
• Symptoms related to underlying conditions (e.g., fibroid-related pressure).

Diagnosis

Diagnosis involves a thorough medical history, physical exam, and specialized tests. Imaging (e.g., ultrasound, MRI, or hysterosalpingography) assesses uterine structure. Hysteroscopy may visualize the uterine cavity directly. Hormonal evaluations and endometrial biopsies check for functional or inflammatory issues. Additional tests rule out other infertility causes.

Treatment Options

Treatment targets the underlying uterine condition. Structural abnormalities (e.g., fibroids, polyps) may be removed surgically. Asherman syndrome may require adhesion lysis. Hormonal therapies or medications address endometrial issues. Assisted reproductive technologies (ART) like IVF may be used if natural conception is unlikely.

Prognosis and Follow-Up

Prognosis depends on the specific uterine issue and its severity. Correctable conditions (e.g., minor polyps) often have good outcomes, while complex malformations may reduce fertility. Follow-up includes monitoring for recurrence, especially after surgery, and ongoing evaluation of reproductive health.

Complications

• Persistent infertility despite treatment.
• Increased risk of miscarriage or preterm birth.
• Surgical complications (e.g., infection, scarring).
• Emotional or psychological stress related to fertility challenges.

Lifestyle & Prevention

• Maintain a healthy weight to reduce fibroid risk.
• Practice safe sex to prevent PID.
• Avoid unnecessary uterine procedures when possible.
• Manage chronic conditions (e.g., endometriosis) to minimize uterine damage.

When to Seek Professional Help

Seek care if you have difficulty conceiving after 12 months of unprotected intercourse, experience abnormal bleeding, or have a history of uterine surgery. Prompt evaluation is important for identifying treatable causes.

Tips for Medical Coders

Use N97.2 for cases where uterine factors are the primary cause of female infertility. Document the specific uterine condition (e.g., fibroids, adhesions) and confirm it is the main contributor to infertility. Ensure differentiation from other infertility causes (e.g., ovarian or tubal) to support accurate coding.
