D44.3 - Neoplasm of uncertain behavior of pituitary gland

Version 2023
ICD-10:D44.3
Short Description:Neoplasm of uncertain behavior of pituitary gland
Long Description:Neoplasm of uncertain behavior of pituitary gland
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
      • Neoplasm of uncertain behavior of endocrine glands (D44)

D44.3 is a billable ICD-10 code used to specify a medical diagnosis of neoplasm of uncertain behavior of pituitary gland. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic craniobuccal pouch ; Neoplasm, neoplastic fossa (of) pituitary ; Neoplasm, neoplastic hypophysis ; Neoplasm, neoplastic intrasellar ; Neoplasm, neoplastic pituitary (body) (fossa) (gland) (lobe) ; Neoplasm, neoplastic Rathke's pouch ; Neoplasm, neoplastic sella turcica ; etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:


Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

Index to Diseases and Injuries References

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:

Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education


Pituitary Disorders

Your pituitary gland is a pea-sized gland at the base of your brain. The pituitary is the "master control gland" - it makes hormones that affect growth and the functions of other glands in the body.

With pituitary disorders, you often have too much or too little of one of your hormones. Injuries can cause pituitary disorders, but the most common cause is a pituitary tumor.
