2024 ICD-10-CM Diagnosis Code D49.1
Neoplasm of unspecified behavior of respiratory system
- ICD-10-CM Code:
- D49.1
- ICD-10 Code for:
- Neoplasm of unspecified behavior of respiratory system
- Is Billable?
- Yes - Valid for Submission
- Chronic Condition Indicator: [1]
- Not chronic
- Code Navigator:
D49.1 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of unspecified behavior of respiratory system. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic antrum (Highmore) (maxillary) ; Neoplasm, neoplastic antrum (Highmore) (maxillary) tympanicum ; Neoplasm, neoplastic aryepiglottic fold laryngeal aspect ; Neoplasm, neoplastic arytenoid (cartilage) ; Neoplasm, neoplastic auditory canal (external) (skin) internal ; Neoplasm, neoplastic auditory tube ; Neoplasm, neoplastic bronchiogenic, bronchogenic (lung) ; etc
Unspecified diagnosis codes like D49.1 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.

Clinical Classification
Clinical Category is Neoplasms of unspecified nature or uncertain behavior
- CCSR Category Code: NEO072
- Inpatient Default CCSR: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
- Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.
Clinical Information
Epiglottis
a thin leaf-shaped cartilage that is covered with laryngeal mucosa and situated posterior to the root of the tongue and hyoid bone. during swallowing, the epiglottis folds back over the larynx inlet thus prevents foods from entering the airway.Eustachian Tube
a narrow passageway that connects the upper part of the throat to the tympanic cavity.Glottis
the vocal apparatus of the larynx, situated in the middle section of the larynx. glottis consists of the vocal folds and an opening (rima glottidis) between the folds.

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.

Patient Education
Lung Diseases
When you breathe, your lungs take in oxygen from the air and deliver it to the bloodstream. The cells in your body need oxygen to work and grow. During a normal day, you breathe nearly 25,000 times. People with lung disease have difficulty breathing. Millions of people in the U.S. have lung disease. If all types of lung disease are lumped together, it is the number three killer in the United States.
The term lung disease refers to many disorders affecting the lungs, such as asthma, COPD, infections like influenza, pneumonia and tuberculosis, lung cancer, and many other breathing problems. Some lung diseases can lead to respiratory failure.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
