0.000What This Code Means
Cancer that involves multiple overlapping sites of the peripheral nerves and autonomic nervous system. This code is used when the tumor spans more than one distinct nerve region.
Coding Tips
- •Use only when tumor involves two or more distinct anatomical sites of peripheral/autonomic nerves
- •Document all involved sites in the medical record to justify use of overlapping sites code
Clinical Significance
Malignant neoplasm of overlapping sites of peripheral nerves and autonomic nervous system indicates a tumor that spans multiple anatomical regions or involves both peripheral and autonomic nerve components. This reflects extensive disease with complex surgical and oncologic management needs.
Documentation Requirements
- ✓Pathology confirming malignant nerve tumor involving multiple sites or nerve systems
- ✓Documentation of all anatomical regions involved
- ✓Imaging demonstrating the overlapping nature of the tumor
- ✓Explanation of why a single site-specific code is insufficient
- ✓Treatment plan addressing the multi-site involvement
Commonly Confused Codes
C47.0-C47.5 (Site-specific peripheral nerve malignancies) — use when a single site is involvedC47.9 (Peripheral nerves, unspecified) — for unknown site, not overlapping sitesC49.8 (Overlapping sites of connective/soft tissue) — soft tissue overlap, not nerveC72._ (Malignant neoplasm of central nervous system) — central, not peripheral nervous system
