Plain-English guides to the parts of California workers'-comp and med-legal billing that actually move money — electronic billing, the Medical-Legal Fee Schedule, Second Review, IBR, reading an EOR, and getting paid on time. Written by the team that builds MindBill.
How an 837P flows through Carisk, Jopari, Data Dimensions, and CorVel — and why electronic bills get paid in days, not weeks.
ML200–ML205, the MLPRR record-review code, and how modifiers 92–98 multiply (not add) to set what a med-legal evaluation is worth.
The first and most important appeal in California work-comp: which reductions to dispute, the 90-day deadline, and what to put on the SBR-1.
When a Second Review is denied, IBR is your binding remedy for fee-schedule amount disputes. The 30-day window, the $180 fee, and when IBR is the wrong tool.
The two forms every California work-comp biller lives in — which boxes matter, what goes in Box 19, and how the SBR-1 attaches to a Second Review.
Decode the Explanation of Review line by line — billed vs. allowed vs. paid, the EOFS, and how to spot an illegal PPO reduction hiding in the math.
CO-45, CO-97, CO-50, CO-16, PR-242 and the rest — what each adjustment reason means, and which to accept versus dispute.
California work-comp penalty and interest are self-executing — a late payer owes them automatically. Here's how much, and from when.
These guides are general information for California workers'-comp and med-legal billers, not legal advice. Statutes and fee schedules change — always confirm against the current DWC regulations for your dates of service.
