Accurate coding for covid 19 is essential for clinical communication, public health surveillance, and correct reimbursement. The diagnosis affects patient care pathways, isolation protocols, and payer coverage decisions. For revenue cycle teams, precise ICD-10 assignment reduces denials, supports medical necessity, and ensures correct claims data for pandemic-related reporting.
This guide explains what the ICD-10-CM code for covid 19 represents, concrete situations when to use U07.1, clear exclusions, related codes to consider, and practical documentation and billing strategies to improve first-pass claim acceptance. It is written for coders, billers, and RCM professionals who need actionable guidance.
The ICD-10-CM Code for COVID-19 is U07.1.
COVID-19 is the clinical illness caused by the SARS-CoV-2 virus, presenting with a spectrum from asymptomatic infection to severe viral pneumonia, acute respiratory distress syndrome, systemic complications, and post-infectious sequelae. Within the ICD-10-CM classification, U07.1 designates a confirmed diagnosis of COVID-19 due to SARS-CoV-2 and is used for encounters where the infectious disease is documented as present. U07.1 is intended for active or confirmed infection; related conditions and manifestations (for example, viral pneumonia or sepsis) should be coded in conjunction with U07.1 when documented.
The ICD-10-CM Code for COVID-19 is U07.1.
COVID-19 is the clinical syndrome resulting from SARS-CoV-2 infection. U07.1 represents a laboratory-confirmed or clinically diagnosed active infection due to that virus, and it should be sequenced based on the reason for the encounter and payer guidance. Use U07.1 when the provider documents COVID-19 as the diagnosis driving care during the encounter.
Use U07.1 when a patient presents with symptoms attributable to SARS-CoV-2 and the provider documents a confirmed COVID-19 diagnosis (by lab test or clinical criteria). Sequence U07.1 as the primary diagnosis if care is motivated by the infection; add manifestation codes (e.g., J12.82 for viral pneumonia) when documented.
Assign U07.1 on emergency department visits or inpatient admissions when COVID-19 is the reason for admission, including cases with respiratory failure, thromboembolic events, or sepsis related to SARS-CoV-2. Include secondary codes that describe organ dysfunction or complications to reflect severity and support medical necessity.
Use U07.1 for follow-up visits focused on active COVID-19 management when the provider documents ongoing infection or active treatment. If the visit pertains to post-COVID conditions without active infection, select the appropriate post-viral or sequela code instead.
When a visit documents a positive SARS-CoV-2 test and the provider records COVID-19 as a diagnosis, code U07.1. If testing is performed and results are negative or pending and the provider documents only exposure or screening, use the appropriate exposure or screening code instead.
Do not use U07.1 for asymptomatic encounters documenting exposure to SARS-CoV-2 or for screening tests without confirmed infection. Instead, use exposure or screening codes as specified by coding guidelines when the provider documents only exposure or screening intent.
Avoid U07.1 for long-COVID or post-COVID sequelae if the provider documents residual symptoms after the acute infection has resolved and does not indicate ongoing active infection. Use codes for sequelae or specific symptom codes that describe the chronic condition.
If documentation specifies a bacterial superinfection, influenza, or another pathogen as the cause of the current illness without COVID-19 confirmation, do not assign U07.1. Code the specific pathogen or condition supported by clinical documentation.
If the provider documents suspicion of COVID-19 but not confirmation and treats under observation or testing only, do not assign U07.1 unless the record contains a confirmed diagnosis statement or positive test result as documented by the clinician.
| Condition | Code | When It Is Used | When It Is Not Used |
|---|---|---|---|
| COVID-19 | U07.1 | Use for confirmed, active SARS-CoV-2 infection documented by provider or positive test and when infection is the reason for the encounter | Do not use for exposure, screening only, or resolved infection with sequelae unless active infection is documented |
| Viral pneumonia due to COVID-19 | J12.82 | Use when provider documents viral pneumonia and links it to SARS-CoV-2; code with U07.1 to identify the infectious agent | Do not use alone if COVID-19 is documented; pair with U07.1 for agent specificity |
| Sepsis due to COVID-19 | A41.89 (or A41.9 if unspecified) | Use when sepsis is documented and the clinician attributes sepsis to SARS-CoV-2; code alongside U07.1 to reflect causative agent | Do not use A41 codes alone if documentation explicitly attributes sepsis to COVID-19 without coding U07.1 |
| Post-COVID condition (sequela) | U09.9 | Use when provider documents post-COVID condition or sequelae after acute infection has resolved and documents sequela relationship | Do not use U09.9 during active infection; use U07.1 for acute, confirmed infections |
Ensure provider notes clearly state “confirmed COVID-19” or document the positive laboratory test and the date. Explicit confirmation and timing support sequencing decisions and medical necessity.
When COVID-19 causes pneumonia, respiratory failure, sepsis, or thromboembolic events, code those manifestations in addition to U07.1. This captures severity and justifies higher levels of care and reimbursement.
Place U07.1 as primary when COVID-19 drives the visit or admission. If a different condition (for example, acute myocardial infarction) is the primary reason and COVID-19 is incidental, sequence accordingly and document clinical relationship.

Q1: What is the ICD-10 code for covid 19?
The ICD-10-CM code for covid 19 is U07.1. Use it when a clinician documents a confirmed active SARS-CoV-2 infection or when a positive test result is recorded and the infection is the focus of care.
Q2: When should I use U07.1 vs related codes?
Use U07.1 for confirmed active COVID-19 and add manifestation codes (for example, viral pneumonia J12.82, or sepsis A41.89) when those conditions are present and documented. For post-infectious sequelae use U09.9; for exposure or screening without confirmed infection use exposure/screening codes instead.
Q3: What documentation is required when coding for covid 19?
Documentation should include the provider’s statement of confirmed diagnosis or linkage to a positive test, the date of onset or test, symptoms and clinical findings, and any complications attributed to the infection. Explicit linkage supports sequencing and medical necessity.
Q4: What are common denial reasons when coding for covid 19?
Common denials stem from using U07.1 without confirmation, failing to document manifestations or complications, coding U07.1 for screening or exposure-only encounters, and inconsistent sequencing. See our guide on denial management for strategies to prevent these denials.
