2022 ICD-10-CM Code J22
Unspecified acute lower respiratory infection
Valid for Submission
| ICD-10: | J22 |
| Short Description: | Unspecified acute lower respiratory infection |
| Long Description: | Unspecified acute lower respiratory infection |
Code Classification
J22 is a billable diagnosis code used to specify a medical diagnosis of unspecified acute lower respiratory infection. The code J22 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 J22 might also be used to specify conditions or terms like acute lower respiratory tract infection, acute respiratory infections, bacterial lower respiratory infection, covid-19, infection of lower respiratory tract and mediastinum , lower respiratory infection caused by sars-cov-2, etc.
Unspecified diagnosis codes like J22 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.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code J22:
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Acute (lower) respiratory (tract) infection NOS
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- upper respiratory infection acute J06.9
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code J22 are found in the index:
- - Infection, infected, infective (opportunistic) - B99.9
- - chest - J22
- - respiratory (tract) NEC - J98.8
- - acute - J22
- - lower (acute) - J22
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Acute lower respiratory tract infection
- Acute respiratory infections
- Bacterial lower respiratory infection
- COVID-19
- Infection of lower respiratory tract and mediastinum
- Lower respiratory infection caused by SARS-CoV-2
- Lower respiratory tract infection
- Postoperative lower respiratory tract infection
- Severe acute respiratory infection
- Viral lower respiratory infection
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code J22 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
| MS-DRG | MS-DRG Title | MCD | Relative Weight |
|---|---|---|---|
| 205 | OTHER RESPIRATORY SYSTEM DIAGNOSES WITH MCC | 04 | 1.6823 |
| 206 | OTHER RESPIRATORY SYSTEM DIAGNOSES WITHOUT MCC | 04 | 0.8842 |
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 J22 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code J22 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.

Information for Patients
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.
