    2016 2017 2018 2019 2020 2021 2022 2023 Billable/Specific Code
  • D35.4 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • The 2023 edition of ICD-10-CM D35.4 became effective on October 1, 2022.

Annotation Back-References
In this context, annotation back-references refer to codes that contain:
  • Applicable To annotations, or
  • Code Also annotations, or
  • Code First annotations, or
  • Excludes1 annotations, or
  • Excludes2 annotations, or
  • Includes annotations, or
  • Note annotations, or
  • Use Additional annotations
that may be applicable to D35.4:
  • C00-D49
    2023 ICD-10-CM Range C00-D49


    • 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 neoplasm of other and unspecified endocrine glands
Clinical Information
  • A benign growth of the cells that comprise the pineal gland. Despite benign histology, symptoms can be produced due to the location: increased intracranial pressure, endocrine abnormalities, cerebellar and/or brainstem compression. The latter can produce a constellation of symptoms known as parinaud's syndrome.
ICD-10-CM D35.4 is grouped within Diagnostic Related Group(s) (MS-DRG v40.0):
  • 054 Nervous system neoplasms with mcc
  • 055 Nervous system neoplasms without mcc
