Letters of Protection in Illinois: How They Work — For Attorneys and Patients
A letter of protection is an attorney’s written commitment that a treating provider’s bill will be protected from the proceeds when the injury case resolves. Paired with a medical lien, it’s how injured clients begin treatment with $0 upfront and no insurance — and how Injury Network Chicago coordinates care for referring firms: (312) 451-0101.
What a letter of protection is
A letter of protection — often shortened to LOP — is a letter from a law firm to a medical provider. In it, the firm commits that when the client’s injury case resolves, the provider’s charges will be protected: paid from the proceeds before disbursement to the client. It’s a written assurance that the provider treating today will not be forgotten at resolution, and it’s one of the standard instruments that make $0-upfront injury treatment possible.
LOP vs. medical lien — and how they work together
The two documents are close cousins. A medical lien is the agreement the patient signs with the provider: treat now, be paid from the case. A letter of protection is the attorney’s commitment layered on top. In practice, many arrangements involve both — the patient’s signed lien and the firm’s letter — and together they give a provider full confidence to treat with nothing due at visits. Injury Network Chicago’s provider network operates on exactly this structure every day, which is why placement happens same-day rather than after a week of provider-side vetting.
For referring attorneys: how we handle the paperwork
When your firm refers a client, the lien and LOP workflow runs through one coordinator. We supply the lien documents, receive and acknowledge your letter of protection, confirm the arrangement with the treating provider, and keep your office copied — so the file’s financial instruments are in place before the first adjustment, not reconstructed before the demand. At treatment’s end, the itemized billing ledger and signed lien documents arrive with the records packet, inside 48 hours of closure.
For patients: what it means for you
Practically, it means access. With a lien in place — and a letter of protection when you’re represented — lien-based treatment starts promptly with nothing due at visits and no insurance involved. Reviewing any document with your attorney before signing is always a reasonable step, and a good arrangement holds no surprises: the terms say what happens, in plain language, for the outcomes a case can have.
Common questions about letters of protection
No — treatment can begin on a signed medical lien alone. When an attorney is involved, the letter of protection is typically added, and we coordinate that paperwork with the firm directly.
