South Carolina Fee Schedule Is a Mod Story, Not Just Compliance
South Carolina held its 2026 medical conversion factor at $52.00. That's a price story. Your experience mod runs on severity, and severity is what a frozen fee schedule doesn't touch.
South Carolina's 2026 medical fee schedule held the medical conversion factor at $52.00 and anesthesia at $32.85 (SC WCC, effective April 1, 2026). Holding the price per service flat is a compliance headline, not a severity ceiling. Utilization, surgery, and independent medical exam fees reaching $3,000 to $4,000 keep claim dollars climbing, and those dollars build your experience mod.
The number everyone read in South Carolina's 2026 fee schedule is the one that didn't move. The medical conversion factor held at $52.00 (SC WCC, effective April 1, 2026). Anesthesia held at $32.85. Underwriters and CFOs saw "held flat" and filed it under good news.
Held flat is a price story. Your mod is a severity story. Those are not the same number.
What the 2026 fee schedule actually froze
A fee schedule sets the price a provider can bill per service. South Carolina's Workers' Compensation Commission approved the 2026 schedule on March 16, 2026, keeping the medical conversion factor at $52.00 and the anesthesia factor at $32.85 (SC WCC, 2026). It updated Evaluation and Management policies and revised CPT and HCPCS codes, but the headline price levers stayed put.
Freezing the price per service does not freeze the cost of a claim. A frozen unit price times more units is still a bigger bill. Frequency of the code, the number of visits, the surgery that gets authorized, the specialist referral: none of that lives in the conversion factor.
The IME line is the tell
The Commission didn't cap what it flagged. It formed an independent medical examination (IME) subcommittee, calling out exam fees "reaching $3,000 to $4,000" and delays in care tied to payment practices (SC WCC, March 2026). An IME is a single line on a claim. At $3,000 to $4,000 a look, on a contested claim that draws two or three of them, the medical spend climbs fast while the conversion factor sits still.
That's the mechanic contractors miss. The compliance document held the price. The cost curve on a real claim runs on utilization, and utilization is exactly what a fee schedule doesn't touch.
Act 185 wired the annual review in
Then the legislature moved. Act 185 (H.3874), signed May 18, 2026, amended Section 42-15-90 to require the Commission to review the fee schedule annually and to weigh the medical consumer price index and the fee schedules of neighboring states (SC statute, 2026). Read that plainly. The state built in a mechanism to let medical prices track inflation over time. The 2026 hold is a snapshot, not a ceiling.
For a contractor, the direction of travel matters more than this year's number. NCCI's (the National Council on Compensation Insurance) 2026 State of the Line described the same national pattern: frequency drifting down, severity drifting up (NCCI SOL, 2026). South Carolina just codified the review process that lets its schedule follow severity.
How a frozen price still lifts your mod
Here's where it lands on the worksheet. Your experience mod (EMR, the Experience Modification Rate) is built from the medical and indemnity dollars on your claims inside the experience period. Primary medical dollars, the portion below the split point, go into the calculation at close to full weight. A fee schedule that holds the price while IMEs, imaging, and surgery push the total up means the same injury posts a larger number on your worksheet than it would have three years ago.
Run it on a real account. A South Carolina contractor with $500,000 in payroll and roughly a $50,000 manual premium sits at the point where mod movement is real money. A 0.05 swing in the mod on that premium is about $2,500 a year, before schedule credits or carrier debits. Two claims that each run a few thousand dollars heavier on medical, thanks to severity the fee schedule doesn't restrain, is enough to move a mod by that much. The renewal doesn't announce it. The multiplier just sits higher.
What an audit would check
An audit doesn't argue with the fee schedule. It checks whether the medical dollars sitting on your worksheet reflect what actually happened on the claim. That means confirming the claim values on your NCCI worksheet match the carrier's current paid-and-reserved figures, that reserves inside your experience period haven't drifted above where the medical facts support them, and that a severity-heavy claim isn't carrying inflated primary dollars into your mod. In our reviews of Southeast contractor worksheets, a stale reserve on a single lost-time claim is the most common reason a mod reads higher than the underlying injuries justify.
A held conversion factor won't lower your premium. A worksheet that reflects reality can lower the mod you multiply against it. Send us your NCCI worksheet and we'll review it for free.
