Guidelines for Medical Necessity Determination for Chromosomal Microarray Analysis

These Guidelines for Medical Necessity Determination (Guidelines) identify the clinical information that MassHealth needs to determine medical necessity for chromosomal microarray analysis. These Guidelines are based on generally accepted standards of practice, review of the medical literature, and federal and state policies and laws applicable to Medicaid programs.

Providers should consult MassHealth regulations at 130 CMR 433.000 and 130 CMR 450.000 and Subchapter 6 of the Physician Manual for information about coverage, limitations, service conditions, and prior-authorization (PA) requirements.

Providers serving members enrolled in a MassHealth-contracted accountable care partnership plan (ACPP), managed care organization (MCO), integrated care organization (ICO), senior care organization (SCO), or program of all-inclusive care for the elderly (PACE) should refer to the ACPP’s, MCO’s, ICO’s, SCO’s, or PACE’s medical policies for covered services.

MassHealth requires PA for chromosomal microarray analysis and reviews PA requests on the basis of medical necessity. If MassHealth approves the request, payment is still subject to all general conditions of MassHealth, including member eligibility, other insurance, and program restrictions.
