Valid for Submission
D38.3 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of mediastinum. The code D38.3 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 D38.3 might also be used to specify conditions or terms like anterior mediastinum mass, neoplasm of anterior mediastinum, neoplasm of posterior mediastinum, neoplasm of uncertain behavior of anterior mediastinum, neoplasm of uncertain behavior of mediastinum , neoplasm of uncertain behavior of posterior mediastinum, etc.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: mediastinum, mediastinal or mediastinum, mediastinal anterior or mediastinum, mediastinal posterior or substernal .
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Anterior mediastinum mass
- Neoplasm of anterior mediastinum
- Neoplasm of posterior mediastinum
- Neoplasm of uncertain behavior of anterior mediastinum
- Neoplasm of uncertain behavior of mediastinum
- Neoplasm of uncertain behavior of posterior mediastinum
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 D38.3 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D38.3 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 D38.3 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.

Chest Injuries and Disorders
The chest is the part of the body between your neck and your abdomen. It includes the ribs and breastbone. Inside your chest are several organs, including the heart, lungs, and esophagus. The pleura, a large thin sheet of tissue, lines the inside of the chest cavity.
Chest injuries and disorders include
- Heart diseases
- Lung diseases and collapsed lung
- Pleural disorders
- Esophagus disorders
- Broken ribs
- Thoracic aortic aneurysms
- Disorders of the mediastinum, the space between the lungs, breastbone, and spine
