| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C50.111 | Malignant neoplasm of central portion of left female breast | Use when the tumor is specifically located in the upper-inner quadrant of the left breast. |
|
| C50.812 | Overlapping sites of left female breast | Use when the tumor spans multiple quadrants and specific origin cannot be determined. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for left breast carcinoma
Decision Criteria
clinical Criteria
- Confirmed tumor location in upper-inner quadrant
documentation Criteria
- Pathology report specifies invasive carcinoma
Applicable To
- Tumor in upper-inner quadrant of left breast
Excludes
- Benign neoplasm of breast (D24.-)
Clinical Validation Requirements
- Imaging or biopsy confirming tumor in upper-inner quadrant
- Pathology report specifying invasive carcinoma
Code-Specific Risks
- Incorrect quadrant documentation leading to unspecified coding
Coding Notes
- Ensure laterality and specific site are documented to avoid unspecified coding.
C50.812 - Overlapping sites of left female breast
Use when the tumor spans multiple quadrants and specific origin cannot be determined.
Applicable To
- Tumor spanning multiple quadrants of left breast
Excludes
- Non-overlapping tumors in separate quadrants
Clinical Validation Requirements
- Operative note indicating tumor spans multiple quadrants
- Imaging showing overlapping tumor sites
Coding Notes
Ensure documentation supports overlapping sites to avoid incorrect coding.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Estrogen receptor positive status
Z17.0Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Left Breast Carcinoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C50.111.
Impact
Clinical: May lead to incorrect treatment planning., Regulatory: Non-compliance with coding guidelines., Financial: Potential for denied claims.
Mitigation Strategy
Always document laterality in clinical notes., Use templates that prompt for laterality.
Impact
Reimbursement: May lead to lower DRG assignment and reimbursement., Compliance: Increases risk of audit due to lack of specificity., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Always use the most specific code available based on documentation.
Impact
Audits may focus on the specificity of breast cancer coding, particularly laterality and site.
Mitigation Strategy
Ensure detailed documentation and use of the most specific codes.
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.
