South Carolina home-care margin recovery: a one-year window that also closes on your fixes.

South Carolina's filing rule is the detail that turns ordinary reconciliation gaps into permanent losses. Most states give an agency one window to file and a separate, longer window to correct and rebill. South Carolina collapses both into a single one-year window from the date of service. A claim has to be filed inside that year, and every resubmission and every void or replacement adjustment has to happen inside that same year too. So when a personal-care claim denies, the clock that is already running is the only clock you get. There is no second, longer runway to fix it.

This page is about where that money leaks in South Carolina specifically, and why catching it means reconciling your EVV visits against the authorization fast, before the one-year window closes on the fix as well as the claim.

EVV captured from the participant's home, at the time of the visit

South Carolina's EVV rule is specific about where and when the visit is captured. The SCDHHS Personal Care scope of service requires that personal-care services be recorded in the state's mandated EVV system from the participant's home at the time of the visit, and documented in the record. The unit of service is one hour of direct personal care. The EVV compliance deadline for personal care services was January 1, 2020, and for home health services January 1, 2023, with EVV launched for the state's developmental-disability-operated waivers in December 2022.

Because the rule ties the capture to the home and the moment of service, the failure modes are about location and timing. A visit clocked from the wrong place, or recorded outside the visit window, does not satisfy the requirement even when the care was real. Providers must follow all EVV system policies, and repeated non-compliance is subject to recoupment and the Sanctioning Guidelines in the scope of service. So the EVV exposure in South Carolina is not only denied claims, it is money clawed back after the fact.

Match the visit, or face denial and recoupment

Here is the South Carolina mechanism. A personal-care claim has to match a verified EVV visit within the state's tolerance. When the EVV record and the schedule or the authorization disagree beyond that tolerance, the claim can be denied or recouped. The exact tolerances and edit detail live in the EVV system policies rather than as a single published code, so the reliable way to find these is to reconcile the visit records against the authorization rather than wait for one tidy denial reason.

That last point is what makes South Carolina unforgiving. In a state with a separate, longer resubmission window, an agency can let denials accumulate and work them in batches. In South Carolina, a denial that is not reworked inside one year of the date of service simply stops being collectible. The recoupment risk compounds it, because a visit that looked paid can be pulled back later, and by then the window to re-establish it cleanly may already be gone.

Where the margin actually leaks in South Carolina

• Location and timing mismatches. Visits not captured from the participant's home at the time of service, so they fail the EVV requirement even though the care happened. This is the core South Carolina EVV leak.
• Recoupment exposure. Claims that paid but get clawed back under the Sanctioning Guidelines for EVV non-compliance, often discovered too late to rebuild cleanly.
• Authorization mismatches. Claims that fall outside the prior authorization on units, dates, or service, common as a member moves across the Community Choices, Community Supports, and HASCI waivers.
• The one-year resubmission trap. Denials that age past one year from the date of service, where the same window that governed filing has already closed on the fix.
• Silent underpayments. Claims that pay below the expected rate, never flagged as a denial, visible only when payment received is compared against payment expected, line by line.

None of these are visible from inside the scheduling view. The schedule says the visit happened. The EVV system says the caregiver clocked in. It is only when you reconcile the EVV visit records against the authorization and the actual remittances that the gap appears, and in South Carolina you have to find it before the year runs out.

Why a read-only recovery layer is the right tool for this

Reeve sits read-only over whatever EMR and EVV export an agency already runs, whether that is WellSky, AxisCare, HHAeXchange, AlayaCare, or anything else, and compares what was delivered with what was authorized and what was actually paid. For a South Carolina agency, that means lining up the EVV visit records, the claim lines, and the prior authorizations, then surfacing every place they fail to reconcile: the location and timing mismatches, the recoupment exposure, the authorization gaps, and the silent underpayments, fast enough to act inside the one-year window.

Because Reeve is read-only and neutral across every EMR, it never writes to your billing workflow without your control, and it has no reason to look past a finding that implicates a billing module. It hands you a ranked list of recoverable dollars with the reason attached. The ones still inside the one-year window are the ones you can rebill now, and in South Carolina that window is doing double duty.

What the free South Carolina Margin Teardown does

The way to find out whether EVV mismatches or recoupment exposure are draining your margin is to look at a real, de-identified slice of your own data, before you spend a dollar. The Margin Teardown is a one-time, read-only read of where margin is leaking in your book: the location and timing mismatches, the authorization gaps, the recoupment exposure, and the underpayments, with the one-year window front of mind. It is free, and it is yours to keep whether or not you ever work with Reeve. It carries the same 3×-or-free guarantee the rest of the engine does. If Reeve does not surface at least three times its monthly fee in recoverable margin you agree is real, you do not pay.
