Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D36.17: its own notes plus those printed at D36.1 and Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Excludes1

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

From D36.1 Benign neoplasm of peripheral nerves and autonomic nervous system applies to 8 codes
  • benign neoplasm of peripheral nerves of orbit (D31.6-)
  • neurofibromatosis (Q85.0-)

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).

Questions About D36.17Overview

Is D36.17 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report benign neoplasm of peripheral nerves and autonomic nervous system of trunk, unspecified on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does D36.17 group to?

When benign neoplasm of peripheral nerves and autonomic nervous system of trunk, unspecified is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 566, 565, with relative weights from 0.7374 to 1.4909 depending on complications. Higher weights mean higher Medicare reimbursement.

Can D36.17 be reported with a code from D31.6?

Not as a rule. The Excludes1 note at D36.1, which applies to D36.17, lists "benign neoplasm of peripheral nerves of orbit (D31.6-)". 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).

What is the ICD-9 equivalent of D36.17?

Under the General Equivalence Mappings, benign neoplasm of peripheral nerves and autonomic nervous system of trunk, unspecified converts to ICD-9-CM 215.9 (ben neo soft tissue NOS). The mapping is approximate, so confirm the match fits the documentation.
