C47 is a non-billable ICD-10-CM category code for malignant neoplasm of peripheral nerves and autonomic nervous system, so it cannot be submitted on claims. Use a more specific code from this category instead, such as C47.0, C47.10, C47.11, and C47.12.

Specific Coding for Malignant neoplasm of prph nerves and autonomic nervous sysOverview

Non-specific codes like C47 require more characters. Use one of these billable codes instead:

  • Use C47.0 for Malignant neoplasm of peripheral nerves of head, face and neck

  • C47.1 for Malignant neoplasm of peripheral nerves of upper limb, including shoulder

  • Use C47.10 for Malignant neoplasm of peripheral nerves of unspecified upper limb, including shoulder

  • Use C47.11 for Malignant neoplasm of peripheral nerves of right upper limb, including shoulder

  • Use C47.12 for Malignant neoplasm of peripheral nerves of left upper limb, including shoulder

  • C47.2 for Malignant neoplasm of peripheral nerves of lower limb, including hip

  • Use C47.20 for Malignant neoplasm of peripheral nerves of unspecified lower limb, including hip

  • Use C47.21 for Malignant neoplasm of peripheral nerves of right lower limb, including hip

  • Use C47.22 for Malignant neoplasm of peripheral nerves of left lower limb, including hip

  • Use C47.3 for Malignant neoplasm of peripheral nerves of thorax

  • Use C47.4 for Malignant neoplasm of peripheral nerves of abdomen

  • Use C47.5 for Malignant neoplasm of peripheral nerves of pelvis

  • Use C47.6 for Malignant neoplasm of peripheral nerves of trunk, unspecified

  • Use C47.8 for Malignant neoplasm of overlapping sites of peripheral nerves and autonomic nervous system

  • Use C47.9 for Malignant neoplasm of peripheral nerves and autonomic nervous system, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to C47: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • malignant neoplasm of sympathetic and parasympathetic nerves and ganglia

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • Kaposi's sarcoma of soft tissue (C46.1)

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • Functional activity
  • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
  • Morphology [Histology]
  • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
  • Primary malignant neoplasms overlapping site boundaries
  • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
  • Malignant neoplasm of ectopic tissue
  • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Autonomic Nervous System Disorders

Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including:

Questions About C47Overview

What is the ICD-10 code for malignant neoplasm of peripheral nerves and autonomic nervous system?

C47 is the ICD-10-CM category for malignant neoplasm of peripheral nerves and autonomic nervous system, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is C47 a billable code?

No. This is a category header that groups the codes for malignant neoplasm of peripheral nerves and autonomic nervous system, and headers cannot be submitted on claims. Claims for malignant neoplasm of peripheral nerves and autonomic nervous system need a more specific code from this category, such as C47.0, C47.10, and C47.11.

Can C47 be reported with C46.1?

Not as a rule. The Excludes1 note on C47 lists "Kaposi's sarcoma of soft tissue (C46.1)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
