Billable Medical Code for Asthma Unspecified Diagnosis Code for Reimbursement Claim: ICD-9-CM 493.9. Code will be replaced by October 2015 and relabeled as ICD-10-CM 493.9. This applies to asthma (bronchial) (allergic NOS), bronchitis: allergic and …
2013 ICD-9-CM Diagnosis Codes 493.*. : Asthma. A chronic disease in which the bronchial airways in the lungs become narrowed and swollen, making it difficult to breathe. Symptoms include wheezing, coughing, tightness in the chest, shortness of breath, and rapid breathing. An attack may be brought on by pet hair, dust, smoke, pollen, mold, exercise, cold air, or stress.
493.90 is a legacy non-billable code used to specify a medical diagnosis of asthma, unspecified type, unspecified. This code was replaced on September 30, 2015 by its ICD-10 equivalent. Convert 493.90 to ICD-10 The following crosswalk between ICD-9 to ICD-10 is based based on the General Equivalence Mappings (GEMS) information:

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a morbidity classification published by the United States for classifying diagnoses and reason for visits in all health care settings. The ICD-10-CM is based on the ICD-10, the statistical classification of disease published by the World Health Organization (WHO). Deaths have been coded using asthma diagnostic codes (ICD-9 Code: 493; or ICD-10 Codes: J45, J46) as the underlying causes of death. However, a clinical modification of the classification for morbidity purposes has been developed by the National Center for Health Statistics (NCHS), the federal agency responsible for use of the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10-CM) in the United States. 1
The ICD-10-CM code sets have updated medical terminology and disease classifications, thus ICD-9-CM and ICD-10-CM are vastly different. There are nearly 5 times as many diagnosis codes in ICD-10-CM than in ICD-9-CM. The clinical modification represents significant changes from ICD-9-CM to ICD-10-CM which include:
The transition from ICD-9-CM to ICD-10-CM will impact public health surveillance activities, particularly those regarding asthma morbidity and healthcare utilization. A major challenge for asthma surveillance is the difference in coding for asthma. There will also be a lag in data collection to analyze trends.
The transition from ICD-9-CM to ICD-10-CM occurred on October 1, 2015. In 2015, asthma hospitalization and emergency department visits data for the first three quarters of the year were coded as ICD-9-CM (493.0-493.9) and the fourth quarter was coded as ICD-10-CM (J45.0-J45.998). If you received 2015 data with both coding schemes, you will have to differentiate ICD-9-CM and ICD-10-CM records to identify asthma-related hospitalization and emergency department visits. However, if your state coded the complete year (2015) using ICD-9-CM codes, then there will be no change to how data are analyzed and reported. For both scenarios, trend analysis will require a dash or other symbol indicating a coding change.
the creation of combination diagnosis/symptom codes to reduce the number of codes needed to fully describe a condition
493.90 is a legacy non-billable code used to specify a medical diagnosis of asthma, unspecified type, unspecified. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
Code also note - A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
NOS "Not otherwise specified" - This abbreviation is the equivalent of unspecified.
Not all people who have asthma have these symptoms. Having these symptoms doesn't always mean that you have asthma. Your doctor will diagnose asthma based on lung function tests, your medical history, and a physical exam. You may also have allergy tests.
Asthma with COPD is classified to code 493.2x. However, all coding directives in the Tabular List and index need to be reviewed to ensure appropriate code assignment. A fifth-digit sub classification is needed to identify the presence of status asthmaticus or exacerbation.
A diagnosis of COPD and acute bronchitis is classified to code 491.22. It is not necessary to assign code 466.0 (acute bronchitis) with 491.22. Code 491.22 is also assigned if the physician documents acute bronchitis with COPD exacerbation. However, if acute bronchitis is not mentioned with the COPD exacerbation, then code 491.21 is assigned (AHA Coding Clinic for ICD-9-CM, 2008, fourth quarter, pages 241-244).
Exacerbation is defined as a decompensation of a chronic condition. It is also defined as an increased severity of asthma symptoms, such as wheezing and shortness of breath. Although an infection can trigger it, an exacerbation is not the same as an infection superimposed on a chronic condition. Status asthmaticus is a continuous obstructive asthmatic state unrelieved after initial therapy measures.
Chronic obstructive pulmonary disease is a chronic bronchitis alpha-1 antitrypsin deficiency that is a genetic form of emphysema. The disease is most of the time characterized by the narrowing or obstruction of airflow and interference that hinders normal breathing. The primary risk factor for chronic obstructive pulmonary disease is smoking or second hand smoking, heredity and air pollution.
When the acute exacerbation of COPD is clearly identified, it is the condition that will be designated as the principal diagnosis. (AHA Coding Clinic for ICD-9-CM, 1988, third quarter, pages 5-6).
Coding and sequencing for COPD are dependent on the physician documentation in the medical record and application of the Official Coding Guidelines for inpatient care.
It is characterized by spasmodic contraction of airway smooth muscle, wheezing, and dyspnea (dyspnea, paroxysmal). Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen.
A chronic respiratory disease manifested as difficulty breathing due to the narrowing of bronchial passageways. A form of bronchial disorder with three distinct components: airway hyper-responsiveness (respiratory hypersensitivity), airway inflammation, and intermittent airway obstruction.
Symptoms include wheezing, coughing, tightness in the chest, shortness of breath, and rapid breathing. An attack may be brought on by pet hair, dust, smoke, pollen, mold, exercise, cold air, or stress. A chronic respiratory disease manifested as difficulty breathing due to the narrowing of bronchial passageways.
In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere.". Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code.
Refer Chapter 10 (Diseases of the respiratory system (J00- J99) in ICD-10-CM for Asthma guidelines.
Need to code both asthma and COPD because asthma with additional specificity can be coded along with COPD.
What happens to our Lungs (Center of respiratory system)during asthma attack: During asthma attack, muscles around the airway gets tighten and the lining inside the airways becomes swollen and produce extra mucus. This makes airway to become narrow and partially block airflow in and out of air sacs.
This type of asthma occurs more than 2 times in a week with regular breathing difficulties to an extent of disturbing daily activities. Moderate persistent. These patients suffer from symptoms daily and last for several days. Severe persistent.
Their symptoms may completely disappear after few years. Experts say this may be due to the growth of airways along with body growth. Cough variant. It is so called because of the main symptom, dry cough. Mild intermittent.
Asthma causes symptoms like shortness of breath, wheezing, coughing or chest tightness. Severity differs in each person.
Inhaler : – Medicine filled inhalers are given to patient to use comfortably at any place when symptoms occurs suddenly.
