Valid for Submission
D15.9 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of intrathoracic organ, unspecified. The code D15.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code D15.9 might also be used to specify conditions or terms like benign neoplasm of intrathoracic organs or benign neoplasm of respiratory system and intrathoracic organ.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: intrathoracic (cavity) (organs) .
Unspecified diagnosis codes like D15.9 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Benign neoplasm of intrathoracic organs
- Benign neoplasm of respiratory system and intrathoracic organ
Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|180||RESPIRATORY NEOPLASMS WITH MCC||04||1.7378|
|181||RESPIRATORY NEOPLASMS WITH CC||04||1.1209|
|182||RESPIRATORY NEOPLASMS WITHOUT CC/MCC||04||0.7875|
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.
Convert D15.9 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D15.9 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 D15.9 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
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.
