0.000What This Code Means
Cancer that develops in the nerves of the pelvic region. This malignant tumor affects peripheral nerve tissue in the pelvis.
Coding Tips
- •Pelvis includes pelvic sidewall and pelvic floor nerves; distinguish from primary pelvic organ cancers
- •Verify documentation specifies peripheral nerve origin rather than other pelvic structures
Clinical Significance
Malignant neoplasm of peripheral nerves of the pelvis involves tumors arising from pelvic plexus or sacral nerve roots in the peripheral distribution. These deeply seated tumors are challenging to resect completely and frequently involve critical neurovascular structures, leading to significant postoperative morbidity.
Documentation Requirements
- ✓Pathology confirming malignant peripheral nerve tumor in the pelvic region
- ✓Specific nerve or plexus involved (sacral plexus, obturator nerve, etc.)
- ✓MRI pelvis showing tumor extent and relationship to pelvic organs
- ✓Functional impact (bladder, bowel, sexual function, lower extremity neurological status)
- ✓Distinction from primary pelvic organ malignancies
Commonly Confused Codes
C49.5 (Malignant neoplasm of connective/soft tissue of pelvis) — soft tissue pelvic sarcoma, not nerve originC47.4 (Peripheral nerves of abdomen) — different anatomical region above the pelvic brimC47.6 (Peripheral nerves of trunk, unspecified) — use C47.5 when pelvis is documentedC76.3 (Malignant neoplasm of pelvis) — ill-defined pelvic site malignancy, not nerve-specific
