Georgia Medicaid has specific billing requirements, MCO contracting rules, waiver programs, and EVV mandates that differ from other states. This page covers what Georgia home care agency operators need to understand to bill correctly, manage authorizations, and avoid the revenue gaps that come from getting any of it wrong.

These aren't general Medicaid billing principles — they're Georgia-specific rules that catch agencies by surprise. Operators moving from another state, or operators building their agency for the first time, make the same mistakes here repeatedly.
EDWP patients are enrolled in one of the four Georgia MCOs. Their care authorizations are managed by MCO case managers. You bill the MCO directly, not GAMMIS, for EDWP patients in managed care.
GAMMIS is primarily for fee-for-service Georgia Medicaid — a minority of patients in most service areas. Most Georgia Medicaid patients are in managed care, so MCO portal fluency matters more than GAMMIS proficiency for daily operations.
Every Georgia Medicaid personal care visit must have a valid HHAeXchange EVV record. Exceptions — GPS mismatches, missed clock-outs — must be resolved before the billing deadline. Unresolved exceptions make visits unbillable. CareBravo's EVV compliance function manages HHAeXchange exception resolution for Georgia agencies.
Each Georgia MCO may use different service codes for the same service type. What bills as T1019 for CareSource may differ from Amerigroup's preferred code. Billing with the wrong code for a specific MCO is a common preventable denial cause.
Amerigroup and Peach State (Centene) are among the higher-enrollment MCOs in the Atlanta metro area where Jackie operates. WellCare and CareSource also have significant enrollment in Georgia. Apply to all four simultaneously — sequential contracting is a common timeline mistake that adds 3-4 months before first patients.
EDWP authorizations are renewed through MCO case managers. The authorization specifies hours per week and service type. Hours authorized but not scheduled before the authorization period ends cannot be retroactively billed — the most significant revenue gap for most Georgia agencies.

100+ agencies. The authorization and billing gaps that produce CareDrain losses look the same in every state — approved hours expiring before they're scheduled, claims denied and left unworked, compliance gaps interrupting billing. The state-specific version of that story in Georgia runs through its MCO landscape and waiver program rules.
Georgia DCH conducts licensing surveys and ongoing compliance surveys. DCH surveyor findings are state-recorded. Caregiver credential lapses, supervisory visit gaps, and care plan documentation deficiencies are common citation areas.
Credential lapses found during a survey are both a compliance deficiency and a billing problem — visits delivered during the lapsed period may not be billable, and survey citations create corrective action requirements. CareBravo's credentialing function tracks every Georgia caregiver credential with expiration alerts and schedule gating before lapses become survey or billing issues.
The Elder and Disability Waiver Program (EDWP) is Georgia's primary Medicaid HCBS waiver for elderly and physically disabled adults who qualify for nursing facility level of care. EDWP funds personal care services, homemaker services, and other HCBS as an alternative to nursing facility placement. EDWP patients are case-managed by the Georgia Medicaid MCOs — Amerigroup, CareSource, Peach State, or WellCare — and their care authorizations are issued and managed by MCO case managers.
Yes. Georgia requires all Medicaid home care agencies providing personal care services to submit EVV data through HHAeXchange, the state's designated EVV aggregator. Agencies can use HHAeXchange's caregiver mobile app directly or use another EVV system that integrates with HHAeXchange for data aggregation. Either way, the EVV data must flow through HHAeXchange — it cannot be submitted to Georgia Medicaid without HHAeXchange processing. MCOs may have additional EVV requirements on top of the state mandate.
GAPP — Georgia Applications Processing Portal — is the online system for Georgia Medicaid provider enrollment and maintenance. Agencies submit their initial enrollment application through GAPP, maintain their provider information, and apply for specific waiver program enrollments (EDWP, NOW, COMP) through the same portal. Base Medicaid enrollment through GAPP is a prerequisite for waiver program enrollment and MCO contracting.
EDWP claims for patients in Georgia managed care are submitted through each MCO's provider billing portal — not through GAMMIS. Each MCO has its own billing portal, service code requirements, and timely filing rules. GAMMIS is used for fee-for-service Medicaid patients, who represent a small minority of most Georgia agencies' patient populations. Most Georgia EDWP patients are enrolled in one of the four MCOs, so MCO portal setup and MCO-specific billing knowledge is the more practically important skill for most Georgia agencies.
The most common Georgia Medicaid home care denial reasons are HHAeXchange EVV mismatch, expired or inactive EDWP authorization, incorrect service code for the specific MCO contract, caregiver credential lapse, and timely filing violations. Most are preventable before submission. CareBravo's pre-submission review checks EVV match, authorization status, service code, and caregiver credential status for every Georgia claim before it leaves the agency.
The billing facts above explain how Georgia Medicaid works. The diagnostic shows what the gaps are costing your specific agency — authorization hours expiring in your waiver program, claims denied and unworked in your MCO mix, compliance issues in your caregiver roster — on your real records.
