Summary
Maryland Medicaid nursing home billing must transition from procedure codes using DHMH 263 forms to revenue codes using UB92/837I format effective April 17, 2004, with revised interim reimbursement rates taking effect January 1, 2004. This represents a major HIPAA-mandated billing format change requiring system updates and staff retraining.
Action Required
By April 17, 2004: Nursing home billing teams must transition from procedure codes/DHMH 263 forms to revenue codes/UB92/837I format for all Maryland Medicaid claims. Update billing software to use new revenue code mappings provided in rate letter. For services prior to April 1, 2004, bill both revenue codes AND procedure codes. For Decubitus Ulcer Care and Medicaid Tube Feeding, use two revenue codes (nursing time + supplies). Convert therapy services to quarter-hour units when billing. Failure to comply will result in claim rejections after April 17, 2004.
