Texas Civil Practice and Remedies Code - CIV PRAC & REM § 146.003. Certain Claims Barred

(a) A health care service provider who violates Section 146.002 may not recover from the patient any amount that the patient would have been entitled to receive as payment or reimbursement under a health benefit plan or that the patient would not otherwise have been obligated to pay had the provider complied with Section 146.002.

(b) If recovery from a patient is barred under this section, the health care service provider may not recover from any other individual who, because of a family or other personal relationship with the patient, would otherwise be responsible for the debt.
