SDP Spark Enrollment: Vendor & Provider Guide
Welcome to Aid FMS. We utilize SDP Spark, a secure platform designed to streamline California’s Self-Determination Program (SDP). This guide outlines the mandatory enrollment process for all providers seeking to render services to participants represented by Aid FMS.
Important Onboarding Policies
-
Payment Timeline: Invoices are typically processed and paid within three weeks of receipt. This timeline is contingent upon the Regional Center’s funding cycle and fiscal department performance. While we strive for consistency, Aid FMS cannot guarantee exact payment dates.
-
Compliance Requirements: As an FMS, we must adhere to strict Medicaid and Department of Developmental Services (DDS) regulations. Your enrollment depends on providing complete documentation that meets these state and federal standards.
Step 1: Document Preparation
Before starting your digital enrollment, ensure you have the following documents ready for upload:
-
IRS Form W-9: Must be the most recent version. Aid FMS performs mandatory IRS TIN Matching; the name and Taxpayer Identification Number must match IRS records exactly to avoid rejection.
-
California State Tax Forms: * In-state vendors: Provide Form CA-590.
-
Out-of-state vendors: Provide Form CA-587.
-
Note: If these forms are not provided, we are legally required to withhold 7% in California state taxes.
-
-
Business Credentials: A copy of your current Business License or City Tax Certificate.
-
Professional Qualifications: Evidence of the qualifications required by Appendix C of the SDP Medicaid Waiver (e.g., specific licenses, degrees, or certifications relevant to your billing code).
-
Background Clearances: Providers delivering "direct care" (e.g., assistance with daily living, hygiene, or safety) must successfully clear a background check before they are authorized to work.
Step 2: Portal Registration
Access the SDP Spark portal to create your provider profile:
-
Registration Link: [Insert Aid FMS Spark Portal Link Here]
-
Account Setup: Click "Vendor Sign Up" and follow the prompts to create your credentials.
-
Email Verification: Check your inbox for a verification link; you must click this to activate your portal access.
Step 3: Complete the Digital Intake
Once logged into your dashboard, complete the following mandatory sections:
-
ACH/Direct Deposit: Input your banking details to enable Electronic Funds Transfer (EFT). This is the required method for receiving timely payments.
-
Service Code Selection: Ensure you select the correct Service (Billing) Code. Verify this code with the participant’s Independent Facilitator (IF) prior to submission.
-
Electronic Signatures: Review and digitally sign the Vendor Agreement and all uploaded tax documentation.
Step 4: Review and Activation
-
Internal Audit: Aid FMS will review your submission for regulatory compliance. We will contact you if any corrections are needed.
-
Approval Status: You will receive an automated email notification once your profile is moved to "Active" status.
-
Invoicing Authorization: Do not submit invoices until your profile is active and you have confirmed the participant’s spending plan is finalized in our system.
