2024 ICD-10-CM Diagnosis Code D15.0

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• Benign neoplasm of superior mediastinum
• Benign neoplasm of superior mediastinum
• Benign neoplasm of thymus
• Benign thymoma
• Myasthenia gravis associated with thymoma
• Thymoma

Clinical Information

• Thymoma

  a neoplasm originating from thymic tissue, usually benign, and frequently encapsulated. although it is occasionally invasive, metastases are extremely rare. it consists of any type of thymic epithelial cell as well as lymphocytes that are usually abundant. malignant lymphomas that involve the thymus, e.g., lymphosarcoma, hodgkin's disease (previously termed granulomatous thymoma), should not be regarded as thymoma. (from stedman, 25th ed)

• Benign Thymoma

  a thymoma that is completely surrounded by a capsule, without evidence of capsular invasion, infiltration of the surrounding tissues, and metastases.

• Experimental Organism Benign Thymoma Neoplasm|THYMOMA, BENIGN

  a benign neoplasm of the thymus, originating from epithelial thymus cells.

D15.0 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
814	RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITH MCC	16	2.1281
815	RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITH CC	16	0.9942
816	RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITHOUT CC/MCC	16	0.7102

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

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.

Filter table of neoplasms:

Neoplasm, neoplastic	Malignant Primary	Malignant Secondary	CaInSitu	Benign	Uncertain Behavior	Unspecified Behavior
»Neoplasm, neoplastic   »thymus (gland)	C37	C79.89	D09.3	D15.0	D38.4	D49.89

Patient Education

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.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

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:

• Growth and development
• Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature
• Sexual function
• Reproduction
• Mood

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.
