D35 is a non-billable ICD-10-CM category code for benign neoplasm of other and unspecified endocrine glands, so it cannot be submitted on claims. Use a more specific code from this category instead, such as D35.00, D35.01, D35.02, and D35.1.

Specific Coding for Benign neoplasm of other and unspecified endocrine glandsOverview

Non-specific codes like D35 require more characters. Use one of these billable codes instead:

  • D35.0 for Benign neoplasm of adrenal gland

  • Use D35.00 for Benign neoplasm of unspecified adrenal gland

  • Use D35.01 for Benign neoplasm of right adrenal gland

  • Use D35.02 for Benign neoplasm of left adrenal gland

  • Use D35.1 for Benign neoplasm of parathyroid gland

  • Use D35.2 for Benign neoplasm of pituitary gland

  • Use D35.3 for Benign neoplasm of craniopharyngeal duct

  • Use D35.4 for Benign neoplasm of pineal gland

  • Use D35.5 for Benign neoplasm of carotid body

  • Use D35.6 for Benign neoplasm of aortic body and other paraganglia

  • Use D35.7 for Benign neoplasm of other specified endocrine glands

  • Use D35.9 for Benign neoplasm of endocrine gland, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to D35: its own notes plus those printed at 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.

  • benign neoplasm of endocrine pancreas (D13.7)
  • benign neoplasm of ovary (D27.-)
  • benign neoplasm of testis (D29.2.-)
  • benign neoplasm of thymus (D15.0)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • code to identify any functional activity

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).

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Questions About D35Overview

What is the ICD-10 code for benign neoplasm of other and unspecified endocrine glands?

D35 is the ICD-10-CM category for benign neoplasm of other and unspecified endocrine glands, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is D35 (Benign neoplasm of other and unspecified endocrine glands) a billable code?

No. This is a category header that groups the codes for benign neoplasm of other and unspecified endocrine glands, and headers cannot be submitted on claims. Claims for benign neoplasm of other and unspecified endocrine glands need a more specific code from this category, such as D35.00, D35.01, and D35.02.

Can D35 be reported with D13.7?

Not as a rule. The Excludes1 note on D35 lists "benign neoplasm of endocrine pancreas (D13.7)". 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).

Does D35 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code to identify any functional activity. The additional code is reported after D35.
