Model II Waiver Services PT (41)

​​​​​​​​​Model II Waiver (MIIW) is Kentucky Medicaid provider type 41. To bill Kentucky Medicaid an MIIW provider must be:  

  • Licensed per 907 KAR 1:595
  • Enrolled as a Kentucky Medicaid provider. ​

Covered Services

MIIW provides Medicaid-paid, in-home skilled services to individuals considered ventilator dependent per 907 KAR 1:022 and who, without MIIW services, would have to live in a hospital-based nursing facility.  

A MIIW provider must meet the coverage provisions and requirements of 9​07​​​ KAR 1:595. Services must be performed within the scope of practice for any provider. Listing of services in an administrative regulation is not a guarantee payment. Providers must follow all relevant state Medicaid regulations. All services must be medically necessary.


Verify eligibility by calling the automated voice response system at (800) 807-1301 or by using the web-based KYHealth-Net System


MIIW services are reimbursed per 9​07 KAR 1:595. Current reimbursement rates for the MIIW are available on the DMS Fee and Rate Schedule webpage​. 

Duplication of Service

Kentucky Medicaid will not reimburse for a service provided to a beneficiary by more than one provider of any program in which the service is covered during the same period. 

Service Authorization

Case managers approve most 1915(c) HCBS services. Kentucky Medicaid reviews requests for high-cost or high-skill servic​es as part of the Kentucky Medicaid Utilization Management (UM) Program​. If you have questions about service authorization, please contact the UM Call Center at (800) 292-2392. ​

Coding: Kentucky Medicaid uses the National Correct Coding Initiative edits and the McKesson Claim Check System to verify incidental or mutually exclusive codes. Kentucky Medicaid also uses Current Procedural Terminology (CPT) codes and Healthcare Common Procedure Coding system codes. Kentucky Medicaid requires the use of ICD-10 codes on all claims submitted for reimbursement. Kentucky Medicaid requires the use of CMS 1500 billing forms. Providers must bill Kentucky Medicaid using the correct CPT codes.

Claim Appeals: Appeal requests made on denied fee-for-service claims must be submitted to Gainwell Technologies and include the reason for the request along with a hard-copy claim.

Timely Filing: Claims must be received the longer of either 12 months from the date of service or six months from the Medicare pay date or within 12 months from the last Kentucky Medicaid denial.
