2021 ICD-10-CM Code D44.9

Neoplasm of uncertain behavior of unspecified endocrine gland

Version 2021

Valid for Submission

D44.9 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of unspecified endocrine gland. The code D44.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

The ICD-10-CM code D44.9 might also be used to specify conditions or terms like neoplasm of uncertain behavior of endocrine gland, neoplasm of uncertain behavior of endocrine glands and nervous system or neoplasm of uncertain behavior of multiple endocrine glands.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic endocrine gland NEC or Neoplasm, neoplastic endocrine gland NEC pluriglandular or Neoplasm, neoplastic gland, glandular (lymphatic) (system) [See Also: Neoplasm, lymph gland] or Neoplasm, neoplastic gland, glandular (lymphatic) (system) [See Also: Neoplasm, lymph gland] endocrine NEC or Neoplasm, neoplastic pluriendocrine .

Unspecified diagnosis codes like D44.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Convert D44.9 to ICD-9 Code

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D44.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The code D44.9 is included 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.

Information for Patients


Endocrine Diseases

Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include

If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels.

In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.
