Endometrial polyps, also known as uterine polyps, are common growths in the inner lining of the uterus. Accurate diagnosis and coding are crucial for medical billing, statistics, and patient care. The ICD-10-CM code N84.0 is specifically used to classify polyp of corpus uteri. This article provides a comprehensive overview of the diagnosis code N84.0, its application, and clinical context.
Decoding ICD-10-CM Code N84.0
ICD-10-CM code N84.0 is designated as a billable/specific code. This means it is precise enough to be used for reimbursement purposes and clearly indicates a diagnosis of polyp of corpus uteri. The code is part of the 2025 ICD-10-CM edition, effective from October 1, 2024. It’s important to note that while N84.0 is the American ICD-10-CM version, international versions of ICD-10 N84.0 may have variations.

ICD-10-CM Coding Guidelines for N84.0
The application of N84.0 is strictly for female patients. This code falls under the broader category of N84, which encompasses polyps of the female genital tract. Specifically, N84.0 is applicable to conditions described as:
- Polyp of endometrium
- Polyp of uterus NOS (Not Otherwise Specified)
It is important to understand “Type 1 Excludes” in ICD-10-CM coding. A type 1 excludes note associated with N84.0 signifies conditions that are “not coded here.” This exclusion indicates that code N84.0 should not be used simultaneously with a condition specifically listed under “type 1 excludes,” implying that these conditions are mutually exclusive with polyp of corpus uteri. For instance, if a congenital form of a uterine condition exists alongside an acquired polyp, the type 1 excludes rule would guide coders to use a different, more appropriate code for the congenital condition, not N84.0. (Note: The original text mentions Type 1 Excludes conceptually but doesn’t list specific exclusions for N84.0.)
Clinical Perspective on Endometrial Polyps
Endometrial polyps are benign nodular lesions that protrude from the surface of the endometrium into the uterine cavity. Clinically, these polyps are characterized by a fibrous stroma containing thick-walled blood vessels and dilated endometrial glands. While typically benign, they can sometimes cause abnormal uterine bleeding, infertility, or pain.
The treatment of choice for endometrial polyps is polypectomy, the surgical removal of the polyp. Recurrence after polypectomy is rare, with only a few cases reported. These polyps are considered benign neoplasms projecting into the endometrial cavity or, less commonly, arising from the endocervix.
Code History and Context of N84.0
The ICD-10-CM code N84.0 is a relatively recent addition, introduced in 2016. The code history for N84.0 shows “New code (first year of non-draft ICD-10-CM) 2016 (effective 10/1/2015)”. From 2017 through 2025, the code has remained unchanged, indicating its established and consistent use in medical coding.
N84.0 sits within a range of related ICD-10-CM codes. Codes adjacent to N84.0 in the ICD-10-CM manual include codes for other noninflammatory disorders of the ovary, fallopian tube, and broad ligament (N83.8, N83.9), as well as other types of polyps in the female genital tract (N84.1-N84.9). Understanding this context helps ensure accurate code selection based on the specific location of the polyp.
Conclusion
The diagnosis code N84.0 is essential for accurately classifying and coding polyp of corpus uteri, a common gynecological condition. This specific and billable code plays a vital role in medical documentation, reimbursement, and tracking the prevalence of endometrial polyps. Healthcare professionals and medical coders should have a clear understanding of N84.0 and its appropriate application within the ICD-10-CM coding system.
