Healthcare Providers

During this challenging and unprecedented event, CareFirst wants to keep you informed of the benefit updates we are making to ensure our members, your patients, have access to the care they need.

Billing and Submitting Claims for Coronavirus Treatment

CareFirst is waiving cost sharing (copays, coinsurance and deductibles) for in-network or out-of-network visits to a provider’s office, lab fees or treatments related to COVID-19. Though CareFirst is waiving out-of-pocket costs, members may experience balance billing from out-of-network providers.

Providers should not collect copays for these services. If a member does owe a copay or coinsurance after the claim is processed, you can bill the member as you do for all other claims.

Billing for Home Births

Home birth services are covered when the member has maternity coverage. When billing for home deliveries, use place of service code 12 and refer to the provider guidelines in the Global Maternity Care Medical Policy ( for procedure coding guidance.

Submitting Claims for Office Visits, Urgent Care or ER Visits

Submit claims for office visits, urgent care, or ER visits for the purpose of diagnosing or ordering testing for COVID-19 using ICD-10 primary diagnosis code of Z20.828 regardless of the place of service. Use the following ICD-10 reporting codes for billing COVID-19 treatment:

  • Treatment of coronavirus- use code U07.1 as primary diagnosis code
  • Treatment of comorbidity symptoms should be submitted with the appropriate diagnosis code

For cases where there was a concern about a possible exposure to COVID-19, but was ruled out after evaluation, submit claims using ICD-10 primary diagnosis code of Z03.818.

Claims for asymptomatic individuals who are being screened for COVID-19, have no known exposure to the virus, and the test results are either unknown or negative, should be submitted using ICD-10 primary diagnosis code Z11.59.

For more information on claims reporting view the CDC’s ICD-10-CM Official Coding and Reporting Guidelines.
