Appealing an underpayment: Second Review → IBR
Step 1 — The underpaid bill and the shortfall
This is a comprehensive medical-legal evaluation that the payer paid at just 12% of the fee schedule — $7,561 below what's owed. Because it's under 99% of MLFS, Mindbill already flags it as recoverable, so the appeal starts from a quantified shortfall rather than a hunch.
Step 2 — Confirm the reduction line by line
The payment cycle moves the bill from processed toward IBR. Line by line, Mindbill posts what the payer allowed against what they paid — the page-by-page record review (MLPRR) came back at 9%, leaving over $7,000 on the table. Confirming the per-line math is how you build an appeal the payer can't wave away: the dispute amount is the sum of those balances.
Step 3 — The spawned Second Review and the 90-day clock
Mindbill spawns the first step automatically: a Second Review. California law gives you 90 days from the EOR to file the DWC SBR-1, and the clock is right here on the bill — e.g. 56 days left. File exactly one SBR per EOR within that window; miss it and the A/R is legally deemed satisfied.
Step 4 — Generate and file the SBR-1
Filing it is one screen. Mindbill pre-fills the appeal reason, lets you attach new supporting records, and picks the dispatch route. It then auto-generates the DWC Form SBR-1 with every bill, claim, and employee field already populated, plus the modified second-review bill — filed via the same clearinghouse the original used and saved to the bill's documents.
Step 5 — Escalate to IBR if the SBR is denied
If the Second Review comes back denied, the next step is Independent Bill Review. Mindbill carries the disputed balance — here $7,560 — onto the DWC IBR-1, tracks the 30-day filing window, and handles the $180 Maximus filing fee, which is refunded by the claims administrator if you win. IBR is only for amount disputes that have already been through one SBR.
Step 6 — The matched-precedent panel (the part nobody else has)
This is the differentiator. Mindbill matches your dispute against thousands of real DWC Independent Bill Review decisions — auto-matched, no manual search — on the exact codes and issues in front of you: here ML203, the MLPRR page count, and the modifier downgrade. The corpus turns a fee-schedule argument into a citation-backed one.
Step 7 — Walk the matched decisions and attach the winners
Each precedent shows whether it was overturned or upheld, the dollars the provider recovered, and a link to the source determination. Attach the winning ones straight to your appeal — the receipts that make Maximus pay. That's how Mindbill turns an underpayment into recovered revenue.
Turning an underpaid med-legal bill into a winning appeal is Mindbill's biggest edge — Second Review, then Independent Bill Review, backed by real DWC precedent. Mindbill auto-matches your dispute against a corpus of thousands of DWC IBR decisions and surfaces the precedents that fit the exact codes and issues in front of you. (The example below is real sandbox data from Bill #3: billed $8,594.00, paid $1,033.25 = 12% of MLFS, $7,560.75 below schedule, ~$4,688 recoverable.)
