Complete code families applicable to Endometrial Adenocarcinoma

C54-C55Primary Range

Malignant neoplasms of corpus uteri

This range includes codes for malignant neoplasms of the endometrium, which is the primary site for endometrial adenocarcinoma.

Other noninflammatory disorders of female genital tract

This range includes codes for conditions that may be associated with or lead to the diagnosis of endometrial adenocarcinoma, such as cervical stenosis and postmenopausal bleeding.

Key Information: ICD-10 code for endometrial adenocarcinoma

Essential facts and insights about Endometrial Adenocarcinoma

The ICD-10 code for endometrial adenocarcinoma is C54.1.

Primary ICD-10-CM Code for endometrial adenocarcinoma

Malignant neoplasm of endometrium
Billable Code

Decision Criteria

clinical Criteria

  • Histopathological confirmation of endometrial adenocarcinoma

documentation Criteria

  • Detailed pathology report specifying histologic type and grade

Applicable To

  • Endometrial adenocarcinoma

Excludes

  • Endocervical adenocarcinoma (C53.9)

Clinical Validation Requirements

  • Histopathological confirmation of endometrial adenocarcinoma
  • Imaging studies showing endometrial thickening

Code-Specific Risks

  • Misclassification with other uterine neoplasms

Coding Notes

  • Ensure histological confirmation before coding.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Cervical stenosis

N88.2
Use when cervical dilation is required for biopsy due to stenosis.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Malignant neoplasm of cervix, unspecified

C53.9
Use p16 and ER/PR markers to differentiate endometrial from endocervical adenocarcinoma.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Endometrial Adenocarcinoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C54.1.

Impact

Clinical: Impacts treatment decisions and prognosis estimation., Regulatory: Non-compliance with cancer registry reporting standards., Financial: Potential for incorrect DRG assignment.

Mitigation Strategy

Use standardized reporting templates, Ensure complete pathology report review

Impact

Reimbursement: Incorrect DRG assignment leading to reimbursement issues., Compliance: Potential for audit discrepancies., Data Quality: Inaccurate cancer registry data.

Mitigation Strategy

Always specify 'endometrial' origin in pathology reports.

Impact

Lack of specificity in histologic documentation can lead to audit findings.

Mitigation Strategy

Use detailed synoptic reporting for all pathology findings.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Frequently Asked Questions

Common questions about ICD-10 coding for Endometrial Adenocarcinoma, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Endometrial Adenocarcinoma

Use these documentation templates to ensure complete and accurate documentation for Endometrial Adenocarcinoma. These templates include all required elements for proper coding and billing.

Postmenopausal bleeding with biopsy-confirmed adenocarcinoma

Specialty: Gynecologic Oncology

Required Elements

  • Patient history
  • Biopsy results
  • Molecular testing results
  • Treatment plan

Example Documentation

62F with postmenopausal bleeding. Biopsy shows endometrioid adenocarcinoma, FIGO grade 1, 30% myometrial invasion. Plan: Laparoscopic hysterectomy.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Endometrial cancer
Good Documentation Example
Endometrioid adenocarcinoma, FIGO grade 1, invading outer third of myometrium (50% invasion), LVSI absent, MMR intact
Explanation
The good example provides detailed histologic and invasion information necessary for accurate coding.
