ICD-9 codes 493: Asthma; 493.0: Extrinsic asthma; 493.00: Extrinsic asthma, unspecified; 493.01: Extrinsic asthma with status asthmaticus; 493.02: Extrinsic asthma with (acute) exacerbation; 493.1: Intrinsic asthma; 493.10: Intrinsic asthma, unspecified; 493.11: Intrinsic asthma with status asthmaticus; 493.12: Intrinsic asthma with (acute) exacerbation
LOINC Code
In ICD-9-CM, asthma with chronic obstructive pulmonary disease is coded as chronic obstructive asthma, unspecified (493.20), chronic obstructive asthma with status asthmaticus (493.21), and chronic obstructive asthma with (acute) exacerbation (493.22).
ICD-10-CM Code for Unspecified asthma with (acute) exacerbation J45. 901.
ICD-Code J45* is a non-billable ICD-10 code used for healthcare diagnosis reimbursement of Asthma. Its corresponding ICD-9 code is 493.
Most ICD-9 codes are three digits to the left of a decimal point and one or two digits to the right of one. For example: 250.0 is diabetes with no complications. 530.81 is gastroesophageal reflux disease (GERD).
Overview. During an asthma attack, also called an asthma exacerbation, the airways become swollen and inflamed. The muscles around the airways contract and the airways produce extra mucus, causing the breathing (bronchial) tubes to narrow. During an attack, you may cough, wheeze and have trouble breathing.
ICD-10 | Fever, unspecified (R50. 9)
Unspecified asthma, uncomplicated J45. 909 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM J45. 909 became effective on October 1, 2021.
493.02 - Extrinsic asthma with (acute) exacerbation. ICD-10-CM.
ICD-10 Code for Severe persistent asthma- J45. 5- Codify by AAPC.
CMS will continue to maintain the ICD-9 code website with the posted files. These are the codes providers (physicians, hospitals, etc.) and suppliers must use when submitting claims to Medicare for payment.
Code Structure: Comparing ICD-9 to ICD-10ICD-9-CMICD-10-CMFirst character is numeric or alpha ( E or V)First character is alphaSecond, Third, Fourth and Fifth digits are numericAll letters used except UAlways at least three digitsCharacter 2 always numeric; 3 through 7 can be alpha or numeric3 more rows•Aug 24, 2015
ICD-9 uses mostly numeric codes with only occasional E and V alphanumeric codes. Plus, only three-, four- and five-digit codes are valid. ICD-10 uses entirely alphanumeric codes and has valid codes of up to seven digits.
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.
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.
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.
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).
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.
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.
