HB 1945 Missouri House · 2026 Regular Session

Modifies provisions relating to health care

HB 1945 modifies Missouri's health care payment system for clinical pathology services under MO HealthNet (the state's Medicaid program). It requires MO HealthNet to pay hospital-based pathologists 30% of Medicare's rate for the "professional component" of their services (interpretation and diagnosis), with payments going directly to the hospital if the pathologist is employed there, or to the third-party provider if not. This affects hospitals, pathologists, and MO HealthNet patients by standardizing reimbursement for these diagnostic services. The bill also adds licensing requirements for drug distributors (section 338.333), but the primary focus is on pathology billing changes.

Introduced House Committee Substitute · 5 edits
MODERATE
The bill was amended to combine HB 1945 with HB 2570, expanding its scope to address both bills. The most significant change involves the definition of 'clinical pathology services,' which was broadened to explicitly include medical judgment in high-complexity laboratory environments. Additionally, the reimbursement mechanism was updated to require payment directly to the licensed physician rather than the hospital, and the funding calculation was adjusted to reference a specific MO HealthNet fee schedule.
Scope change
The bill's scope was expanded by merging it with HB 2570, indicated by the title change from 'House Bill No. 1945' to 'House Bill Nos. 1945 & 2570'.
DEFINITION

The definition of 'clinical pathology services' was expanded to explicitly include services involving medical judgment in high-complexity laboratory environments, clarifying what constitutes a professional service.

FISCAL

The reimbursement calculation was changed to be based on 'no less than thirty percent' of the approved MO HealthNet Independent Lab - Technical Component fee schedule, replacing the previous reference to Medicare's schedule.

REQUIREMENT

A new requirement mandates that payment for professional clinical pathology services be made directly to the licensed physician or the entity they assign, rather than to the hospital.

New language was added to address the need for federal Medicaid state plan amendments, requiring the department to seek approval and implement reimbursement to the fullest extent permitted by state and federal law.

SCOPE

The bill title and header were updated to reflect that it is now a combined substitute for House Bills 1945 and 2570.
