Introduction: Why Understanding the Endometrial Cancer ICD-10 Code Matters
If you or someone you love has been diagnosed with endometrial cancer, chances are you’ve come across a long string of letters and numbers on your medical records—something like C54.1 or C55. These aren’t random codes. They’re part of the ICD-10 system, used to classify diseases worldwide. But what exactly is the endometrial cancer ICD-10 code, and why should you care?
In this post, we’ll break down what these codes mean, how they’re used in U.S. healthcare today, and why they matter for everything from insurance coverage to accurate treatment planning.
What Is Endometrial Cancer?
Endometrial cancer is the most common form of uterine cancer and begins in the lining of the uterus, known as the endometrium. It typically affects women after menopause but can also develop earlier.
Common symptoms include:
- Abnormal vaginal bleeding (especially post-menopause)
- Pelvic pain or cramping
- Pain during intercourse
- Unexplained weight loss
- Fatigue
If detected early, endometrial cancer has a high survival rate. In fact, the five-year survival rate for localized endometrial cancer in the U.S. is 95% according to the American Cancer Society.

What Is the ICD-10 Code for Endometrial Cancer?
The ICD-10 (International Classification of Diseases, 10th Revision) is a coding system used by medical professionals to classify diagnoses, symptoms, and procedures. These codes are used for:
- Medical billing
- Insurance claims
- Epidemiology tracking
- Research and treatment planning
Primary ICD-10 Codes for Endometrial Cancer:
- C54.1 – Malignant neoplasm of the endometrium
- C54.9 – Malignant neoplasm of unspecified part of the corpus uteri
- C55 – Malignant neoplasm of uterus, part unspecified
These codes help ensure the accurate classification of cancer based on location and type.
Why Multiple ICD-10 Codes?
Endometrial cancer doesn’t always present the same way. Physicians may use a more specific or broader code based on the available diagnosis.
Here’s a quick breakdown:
| ICD-10 Code | Description |
|---|---|
| C54.1 | Cancer specifically located in the endometrium |
| C54.9 | Cancer in an unspecified part of the uterine corpus |
| C55 | Uterine cancer where the exact location is unclear or unrecorded |
These distinctions are especially important in cases involving second opinions, insurance approvals, and national cancer registries.

Updated Trends and Guidelines (U.S., 2024–2025)
Endometrial cancer rates are increasing, particularly among younger and obese women, according to recent data from the National Cancer Institute (NCI).
Key 2025 Statistics:
- Over 66,000 new cases of uterine cancer are expected in the U.S. in 2025.
- It is the fourth most common cancer among women in the U.S.
- Obesity is a leading risk factor—linked to more than 50% of new cases.
- Black women are more likely to be diagnosed at later stages and have lower survival rates.
In response, public health policies now include:
- Earlier screenings for high-risk individuals
- Expanded genetic counseling for hereditary cancers
- Federal funding for obesity prevention programs
How the ICD-10 Code Impacts Patients
You might not think much about medical codes, but they play a big role in your cancer journey.
Here’s how:
- Insurance Claims: Your treatment may not be covered unless properly coded with ICD-10.
- Medical Records: These codes provide a snapshot of your condition across different health systems.
- Clinical Trials: Accurate coding determines eligibility for clinical research programs.
- Treatment Planning: Specialists may use specific codes to coordinate surgery, radiation, or chemotherapy.
For example, someone coded under C54.1 may be eligible for targeted endometrial cancer trials, while a C55 code might require further diagnostic clarification.
Diagnosing Endometrial Cancer
Diagnosis typically involves:
- Transvaginal ultrasound
- Endometrial biopsy
- Hysteroscopy
- Dilation and curettage (D&C)
- CT or MRI scan (to check for spread)
Once diagnosed, an ICD-10 code is assigned to track treatment and progress.

Treatments Linked to Endometrial Cancer
Treatment options vary by cancer stage and type, but most plans include:
- Surgery – Often a total hysterectomy (removal of uterus)
- Radiation therapy – Used post-surgery in high-risk cases
- Hormone therapy – For estrogen-sensitive tumors
- Chemotherapy – For advanced or aggressive forms
In 2025, emerging treatments include immunotherapy and targeted therapies for genetic mutations such as MSI-H or Lynch syndrome.
High-Risk Populations and Genetic Testing
Certain genetic mutations increase the risk of endometrial cancer. These include:
- Lynch syndrome (hereditary nonpolyposis colorectal cancer)
- BRCA1 and BRCA2 mutations
- PTEN and P53 gene mutations
If you have a family history of uterine, colon, or ovarian cancers, your doctor may recommend genetic counseling and testing. Many insurers in the U.S. are now required to cover these services under ACA mandates for at-risk individuals.
Tips for Living Well with Endometrial Cancer
Whether you’re in treatment or recovery, a healthy lifestyle can support healing and reduce recurrence risk:
✅ Maintain a healthy weight
✅ Eat a fiber-rich, plant-based diet
✅ Exercise regularly (as advised by your doctor)
✅ Quit smoking
✅ Stay consistent with follow-ups and screenings
ICD-10 Coding: What Healthcare Providers Should Keep in Mind
For medical coders and providers, precise ICD-10 documentation is critical to:
- Ensure accurate billing and avoid claim rejections
- Support clinical documentation improvement (CDI) initiatives
- Comply with HIPAA and CMS regulations
- Enable population health tracking and cancer surveillance
Coding education in 2025 has seen a rise in AI-supported coding tools—but human oversight remains essential for conditions as complex as endometrial cancer.
Final Thoughts: Why the Endometrial Cancer ICD-10 Code Is More Than Just a Number
The endometrial cancer ICD-10 code may seem like just a technical detail, but it plays a crucial role in how care is delivered, tracked, and reimbursed in the U.S. healthcare system.
Whether you’re a patient trying to understand your diagnosis, a caregiver navigating insurance claims, or a provider documenting treatment, accurate coding ensures better outcomes for everyone.
Stay Informed, Ask Questions, and Advocate for Your Health
If you or someone you know is navigating a uterine cancer diagnosis, ask your provider to explain your ICD-10 code and how it impacts your treatment and care.
Being informed is the first step toward better outcomes.
