C75: ICD10 Code for Malignant neoplasm of other endocrine glands and related structures
C75 is the ICD10 code used for documenting Malignant neoplasm of other endocrine glands and related structures in clinical and billing records.

C75 refers to Malignant neoplasm of other endocrine glands and related structures, a group of cancers arising from the hormone-secreting glands such as the thyroid, adrenal glands, or other endocrine tissues. These malignancies may affect hormone levels, cause systemic symptoms, and often require multidisciplinary management. ICD10 coding ensures clear classification, documentation, and appropriate treatment planning.
Symptoms
- Neck lump or swelling – Typical of thyroid cancers
- High blood pressure – Common in adrenal gland tumors
- Unexplained weight loss or gain – Due to hormone imbalance
- Palpitations or anxiety – From excess thyroid or adrenal hormones
- Fatigue and weakness – Often related to hormonal disruption
- Changes in appetite or mood – Caused by endocrine dysfunction
- Hoarseness or difficulty swallowing – In thyroid gland involvement
Diagnosis
Diagnosis of Malignant neoplasm of other endocrine glands and related structures involves hormonal assays, imaging studies (ultrasound, CT, MRI), nuclear medicine scans, and biopsy. Endocrinologists and oncologists collaborate to evaluate tumor type, hormonal activity, and malignancy potential. Genetic testing may also be relevant in hereditary syndromes.
ICD10 Code Usage
ICD10 code C75 is used in endocrinology, oncology, and surgery to classify endocrine malignancies. It supports insurance billing, cancer registry data entry, and outcome analysis, and helps guide targeted treatments such as hormone-suppressive therapies or surgery.

Q4: What is the prognosis?
A: Prognosis varies by tumor type and stage. Thyroid cancers often have excellent outcomes with early treatment.
Q5: Who treats these cancers?
A: Typically managed by a team including endocrinologists, oncologists, surgeons, and radiologists.
