ImmuNet is Maryland's Immunization Information System (IIS). It is a secure web-based registry operated by the Center for Immunization at the Maryland Department of Health (MDH). ImmuNet information is confidential and available only to authorized users. To read more on the benefits of IIS please go here.
As of October 2019, all vaccinations administered in the State of Maryland are required to be reported to Maryland's Immunization Information System, ImmuNet, regardless of patient opt-out status in ImmuNet (see more info about patient opt-out here). All vaccination data should be reported on the same day or within one day of administration.
Note: Starting July 1, 2022, the exemption in §18–109(d)(6)(II) will be deleted. This means that vaccine providers who administers a vaccine in a nursing facility, an assisted living program, a continuing care retirement community, or a medical day care program will be required to report to ImmuNet.
Reporting COVID-19 Vaccinations
All administered doses of COVID-19 vaccines must be reported to ImmuNet per the CDC Provider Agreement and within 24 hours per the Governor's Executive Order 21-01-05-01. To meet this requirement, the most efficient options to report to ImmuNet are through Electronic Health Records (EHRs) or csv file uploads.
Please see here for the list of CDC/MDH-required data elements to report to ImmuNet.
Providers eligible to order COVID-19 vaccines through ImmuNet must report administered doses under each location’s unique Organization ID for accurate vaccine allocation and inventory reconciliation.
To ensure you are in compliance with the State Statute §18–109(d)(6)(I)3 to Report to ImmuNet all vaccines administered, please see the section below that applies to you.
How can providers tell if they are already reporting to ImmuNet?
Sign in to ImmuNet to check if your patients' vaccination records from your practice are already in ImmuNet. No ImmuNet access? Get access here.
Providers should put in a ticket with their EHR/EMR vendor to prepare their interface according to the ImmuNet specifications. When a test file is ready, contact ImmuNet Support for the onboarding team to assist with the testing/validation process.
ImmuNet supports bidirectional data exchange through the Maryland State Health Information Exchange partner, CRISP. Instructions for onboarding with CRISP can be found here.
Note: ImmuNet conforms to the CDC HL7 2.5.1 Implementation Guide for Immunization Messaging, Release 1.5 and Addendum, including supporting Query/Response, acknowledgment messaging, and the receipt of National Drug Codes (NDC) for newly-administered immunizations.
Providers who participate in the CMS Promoting Interoperability (PI) programs (aka EHR Incentive Program, Meaningful Use or MIPS) may already be registered to report to ImmuNet. If you are still in the queue and have a TEST file ready to submit, please contact the Public Health Reporting Help Desk. Note that participants must report from certified technology with Query/Response (bidirectional data exchange) capabilities and send NDC codes.
Multiple locations sharing the same electronic Health Records (EHR) system can register and onboard together as a group effort. However, each location/site will be assigned a separate Organization ID in ImmuNet.
The Maryland Department of Health (MDH) strongly recommends reporting vaccination data to ImmuNet through an EHR/EMR. A direct connection between your EHR/EMR and ImmuNet is the most efficient, cost-saving and reliable method to ensure your vaccination data is reported in compliance with Maryland law. If you do not have an EHR or EMR, MDH strongly recommends getting an EHR/EMR (there are a few low-cost or free options available).
If EHR/EMR is not a feasible option for you, there are two other methods of reporting to ImmuNet:
1. Upload CSV files on a daily basis.
Use the CRISP CSV-HL7 file conversion upload method (see instructions) to automate submission for CRISP to auto-convert the file to HL7 format (which will allow ImmuNet to deduct and reconcile your inventory). Please contact ImmuNet Support when you are ready to submit a test file. Do not include real patient data in your test file and do not email any files for confidentiality/security reasons.
Once testing is completed, you can submit CSV files using SFTP on an ongoing basis.
2. Manual Data Entry
Enter patient vaccination data (other than COVID-19) manually in ImmuNet on a daily basis. Note this option does not apply for COVID-19 vaccination data reporting. For vaccination data other than COVID-19, please review the ImmuNet Basic Guide for guidance. You will need to have an ImmuNet account.
