What Maryland’s texts say
The policy guide opens its description plainly: Maryland’s EVV system “is a smartphone application and phone-based electronic billing system.” The PDN and home health portal manual spells out the acronym behind the phone line, “ISAS – In-home Supports Assurance System.” And COMAR 10.09.36.03-2 lists what a record holds: “service type, provider and participant information, date of service, service delivery location, and beginning and ending times of service.”
A state-built system
Where many states let agencies shop for an EVV vendor, Maryland runs one system through LTSSMaryland. COMAR 10.09.36.03-2 points agencies and workers to the method the department approves, with exemptions the department grants, and lets self-directing participants use the EVV of an approved financial management and counseling services contractor. A live-in caregiver who qualifies for the exemption may elect a manual or other electronic timekeeping process under the same regulation.
App, phone line and OTP device
The Maryland Medicaid EVV policy guide, updated August 2025, makes the LTSSMaryland mobile app the normal way to clock in and out, with offline mode or the ISAS telephone as fallbacks. The ISAS call goes from a number listed in the participant’s LTSSMaryland profile, and the policy guide warns that calls from unlisted numbers are investigated and affect payment. The Provider Portal reference guide of August 2025 sends workers to a one-time password device in listed cases, care outside the participant’s home among them.
Location without the word GPS
None of the Maryland texts read here mentions GPS. The Provider Portal guide of August 2025 and the PDN and home health portal manual both say location services stay switched on while the app is open, and the guide adds that the app stops collecting location once closed. COMAR 10.09.36.03-2 defines EVV as recording, among other details, the service delivery location, but the telephone and OTP routes record visits too, so no Maryland text read here asks that every visit be located by satellite.
Gaps in this reading
The training page’s FAQ, app and ISAS panels load by script and could not be read. The developmental disabilities administration’s go-live notice returned an error. The effective date of COMAR 10.09.36.03-2 was not displayed, and Health-General § 7-309 only protects users of the administration’s services from harm by the system; it sets no EVV duty.
Where LockProof stands in Maryland
Maryland visits go into the department’s own system. A LockProof photo goes to people outside it, such as an adult child keeping watch over how a parent is looked after, or someone covering the agency’s bill from savings. Background reading: photo proof alongside a state EVV system; plus how a LockProof caregiver photo is built.
Reading date
All of these Maryland texts were read November 2, 2026; the department updates its guides, and a newer edition may differ. The wider set of states is gathered on our state-by-state EVV hub, and Pennsylvania, along Maryland’s northern border, gets its own treatment on a Pennsylvania page.
Common questions
Who runs EVV in Maryland?
The Maryland Department of Health. Its own EVV policy guide, updated August 2025, describes the system as a smartphone app plus a phone-based billing line, run through LTSSMaryland. In a letter of December 14, 2022 approving the state’s home health exemption, CMS classed it as an in-house model in which the state itself sets the EVV tools. None of the state pages read here names a commercial vendor behind it.
When did Maryland start using EVV?
Long before the federal deadline. The Maryland Medicaid EVV policy guide, updated August 2025, says the department implemented EVV in 2013 in place of paper billing, and its ISAS telephone policy carries an effective date of October 3, 2013. Home health and private duty nursing followed: the Maryland Medicaid home health and PDN policies took effect November 9, 2023, and claims for services from November 30, 2023 go through the Provider Portal.
Does Maryland EVV use GPS?
The state’s texts never use the word. What the Maryland Medicaid Provider Portal guide of August 2025 says is that location services stay on while the LTSSMaryland EVV app is in use, and that the app does not follow anyone once it is closed. The Maryland Medicaid EVV policy guide, updated August 2025, sends a worker to offline mode or the ISAS telephone line, from a number authorized in the participant’s profile, when the app is unavailable; the Provider Portal guide adds a one-time password device in listed cases, such as care outside the participant’s home.
How does Maryland handle a missed clock-in?
Through a missing time request. The Maryland Medicaid EVV policy guide, updated August 2025, gives an agency 30 calendar days from the date of service to send one and caps approvals at four a month per staff member in personal care programs; the home health and PDN policies of November 9, 2023 set six a month per clinician. The Provider Portal manual of October 2023 adds that exceptions left unresolved past 90 days are disapproved.
Is LockProof part of LTSSMaryland?
No. Flatly stated, LockProof is not an EVV system; Maryland’s Department of Health has not approved it under COMAR 10.09.36.03-2, and LTSSMaryland takes nothing from it. Maryland visits are recorded in the department’s own app, phone line or OTP device. What LockProof offers is something else: a sealed, time-marked visit photo an agency might forward to relatives or to someone buying care privately.
Does this Maryland page give legal advice?
It cannot. This page restates Maryland Health Department texts as read on November 2, 2026; the department revises its guides often. The effective date of COMAR 10.09.36.03-2 was not shown on the page read. Any question about one agency’s billing belongs with its lawyer, the department or its program contact.
