ICD-10 Diagnosis Code C34.81

• 180 - RESPIRATORY NEOPLASMS WITH MCC
• 181 - RESPIRATORY NEOPLASMS WITH CC
• 182 - RESPIRATORY NEOPLASMS WITHOUT CC/MCC

• 162.8 - Mal neo bronch/lung NEC (Approximate Flag)

Also called: Bronchogenic carcinoma

Lung cancer is one of the most common cancers in the world. It is a leading cause of cancer death in men and women in the United States. Cigarette smoking causes most lung cancers. The more cigarettes you smoke per day and the earlier you started smoking, the greater your risk of lung cancer. High levels of pollution, radiation and asbestos exposure may also increase risk.

Common symptoms of lung cancer include

• A cough that doesn't go away and gets worse over time
• Constant chest pain
• Coughing up blood
• Shortness of breath, wheezing, or hoarseness
• Repeated problems with pneumonia or bronchitis
• Swelling of the neck and face
• Loss of appetite or weight loss
• Fatigue

Doctors diagnose lung cancer using a physical exam, imaging, and lab tests. Treatment depends on the type, stage, and how advanced it is. Treatments include surgery, chemotherapy, radiation therapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

• Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
• No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
• Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.

Present on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.
