Treating a patient who is immunocompromised poses more risks and challenges; therefore, it is important to identify a patient with this status. Code D84. 821, Immunodeficiency due to drugs, was created for immunodeficiency due to medications that interfere with the immune system.
Immunodeficiency disorders impair the immune system's ability to defend the body against foreign or abnormal cells that invade or attack it (such as bacteria, viruses, fungi, and cancer cells). As a result, unusual bacterial, viral, or fungal infections or lymphomas.
Clinical ModificationUnderstanding ICD-10 (ICD-10-CM) ICD-10-CM, which stands for International Classification of Diseases, 10th Revision, contains two code sets. They are ICD-10-CM, Clinical Modification; and ICD-10-PCS, Procedure Coding System.
When the communicable disease in question is COVID-19, the appropriate ICD-10 code is Z20. 828, “Contact with and (suspected) exposure to other viral communicable diseases.”
Who is immunocompromised? People who are considered immunocompromised include those diagnosed with HIV, AIDS, cancers like leukemia and Hodgkin lymphoma,3 alcoholism, diabetes mellitus, kidney disease, hepatitis, lupus, and congenital disorders (disorders present at birth, such as cystic fibrosis).
When your immune system fails to respond adequately to infection, it's called an immunodeficiency, and you may be immunocompromised. People may also suffer from the opposite condition, an overactive immune system that attacks healthy cells as though they were foreign bodies, and that is called an autoimmune response.
The main differences between ICD-10 PCS and ICD-10-CM include the following: ICD-10-PCS is used only for inpatient, hospital settings in the U.S., while ICD-10-CM is used in clinical and outpatient settings in the U.S. ICD-10-PCS has about 87,000 available codes while ICD-10-CM has about 68,000.
A Five-Step ProcessStep 1: Search the Alphabetical Index for a diagnostic term. ... Step 2: Check the Tabular List. ... Step 3: Read the code's instructions. ... Step 4: If it is an injury or trauma, add a seventh character. ... Step 5: If glaucoma, you may need to add a seventh character.
The first is the alphabetic abbreviations “NEC” and “NOS.” NEC means “Not Elsewhere Classified” while NOS means “Not Otherwise Specified.” Simply put, NEC means the provider gave you a very detailed diagnosis, but the codes do not get that specific.
For individuals with MIS and COVID-19, assign code U07. 1, COVID-19, as the principal/first-listed diagnosis and assign code M35. 81 as an additional diagnosis. If MIS develops as a result of a previous COVID-19 infection, assign codes M35.
For cases where there is a concern about a possible exposure to COVID-19, but this is ruled out after evaluation, assign code Z03. 818, Encounter for observation for suspected exposure to other biological agents ruled out.
Assign a code(s) explaining the reason for encounter (such as fever, or Z20. 828).
