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 mets to bone
Decision Criteria
clinical Criteria
- Presence of metastatic lesions on imaging
coding Criteria
- Primary cancer site known and documented
Applicable To
- Bone metastasis
Excludes
- Multiple myeloma (C90.00)
Clinical Validation Requirements
- Imaging studies confirming bone lesions
- Histological confirmation of metastatic cancer
Code-Specific Risks
- Incorrect sequencing with primary cancer codes
- Misuse in conditions like multiple myeloma
Coding Notes
- Ensure primary cancer is documented if known; otherwise, use C80.1.
C50.--- - Malignant neoplasm of breast
Use when breast cancer is the primary site of metastasis.
Applicable To
- Breast cancer
Clinical Validation Requirements
- Histological confirmation of breast cancer
Coding Notes
Ensure laterality and specific site within the breast are documented.
C80.1 - Malignant (primary) neoplasm, unspecified
Use when the primary site of cancer is not documented.
Clinical Validation Requirements
- Lack of documentation for primary cancer site
Coding Notes
Use only when primary site cannot be determined.
Ancillary Codes

C90.00Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Bone Metastases to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C79.51.
Impact
Clinical: Incomplete clinical picture., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Review patient history for primary cancer documentation, Ensure all relevant codes are included
Impact
Reimbursement: May lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate representation of patient condition.
Mitigation Strategy
Do not use C79.51; bone involvement is integral to multiple myeloma.
Impact
Reimbursement: Incorrect DRG assignment., Compliance: Violates CMS coding guidelines., Data Quality: Misleading data on cancer treatment focus.
Mitigation Strategy
Sequence secondary code first if treatment is for metastasis.
Impact
Failure to sequence codes correctly based on treatment focus.
Mitigation Strategy
Regular training on ICD-10 guidelines and CMS updates.
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.
