When did you last bill a carrier for paying you late?
For almost every practice in California the answer is never. Not because the money isn’t owed — Labor Code §4603.2 increases a late-paid treatment bill by 15 percent with interest, and §4622 adds 10 percent with interest to a late-paid medical-legal bill. Both are self-executing: owed by operation of law, with no dispute to file and nobody’s permission to ask.
Almost nobody collects it, because collecting it means knowing the exact date a properly documented bill was received, counting calendar days rather than business days, and doing that for every charge in the practice. That is not a discipline problem. It is a bookkeeping problem, and it is the kind of problem software is actually good at.
Put your own numbers in.
The figures below are placeholders, not claims about your practice — replace them. The percentages are the statute’s and cannot be changed; everything else is yours.
Your estimate, not ours. If you have never measured it, that is itself the finding.
§4622 · 60 days · a 10% penalty and 7% interest, on a much larger average bill.
Two bill types, two clocks, both in calendar days.
| Bill type | Payment due | If late | Interest |
|---|---|---|---|
Treatment bill LC §4603.2 | 45 calendar days | 15% increase | 10% per annum, retroactive to receipt civil-judgment rate, CCP §685.010 |
Medical-legal bill LC §4622 | 60 calendar days | 10% penalty | 7% per annum self-executing |
The §4603.2 clock was counted in business days in an earlier build of this product and corrected to calendar days on 13 September 2026. We mention it because the difference is roughly two weeks per charge, and because a vendor who will not tell you what they got wrong is not telling you much.
An estimate is an argument for looking, not a receipt.
It is deliberately conservative
Nothing compounds, and medical-legal interest is accrued only from the 60-day deadline rather than from receipt. A number you don’t believe is worth less than no number, so where the reading is arguable this one takes the low side.
Entitlement turns on facts we can’t see
Whether the bill was properly documented, the date it was actually received, and whether the carrier has a defence. This page is not legal advice and not a promise of recovery.
The real number comes off your EORs
Every explanation of review carries the dates the calculation actually needs. One month of them turns the estimate above into a figure with charge numbers attached.
Going forward is the larger half
Recovering what is already late is one conversation. Never being late-paid without billing for it again is the part that compounds, and it is what the revenue cycle is built to do.
Bring one month of EORs and we will do this properly.
We will walk the money path on your own paper — what was paid late, what the statute entitles you to on it, and which denials still have a live second-review window. You keep the findings whether or not you ever buy anything. That is a more useful forty minutes than any slide we could show you.
