Chiropractic insurance billing in Georgia.

Medicare’s chiropractic rules are federal — the same in every state. Medicare Part B covers ONLY manual manipulation of the spine to correct a subluxation (CPT 98940–98942), and ONLY when the care is active or corrective — which you signal with the AT modifier. Maintenance care, exams, X-rays, and any therapies performed by a chiropractor are not covered, so a properly executed ABN is essential before non-covered services. The full federal rules are in our chiropractic Medicare billing guide.

Part B claims in Georgia are processed by Palmetto GBA (JJ) — its Local Coverage Determination and documentation expectations (and its audits of the AT modifier and medical necessity) are the ones your Georgia claims are measured against.

A Georgia chiropractic or multi-specialty practice spends most of its commercial billing day with: Anthem Blue Cross Blue Shield of Georgia (Elevance); UnitedHealthcare; Aetna (CVS Health); Cigna; Kaiser Permanente; Humana. Each has its own claim portal, fee schedule, and chiropractic medical-policy quirks.

The dominant DELEGATED musculoskeletal/chiropractic network managers operating in Georgia are American Specialty Health (ASH) and Optum (UnitedHealth Group), plus Carelon Medical Benefits Management (formerly AIM Specialty Health) for utilization management on Anthem.

• AMERICAN SPECIALTY HEALTH (ASH) — ASH is active in Georgia and administers chiropractic (and often acupuncture, and in many markets physical/occupational therapy) for CIGNA: when a Cigna plan delegates to ASH, network contracting, the treatment plan/medical-necessity review, and CLAIMS route to ASH (ashlink.com), NOT to Cigna directly; ASH separately has had Aetna and other health-plan relationships. So a Cigna chiropractic claim or auth sent to Cigna instead of ASH is a common denial cause — check the member card.
• OPTUM / Optum Physical Health (UnitedHealth Group) — manages chiropractic and outpatient therapy for UnitedHealthcare; UHC requires prior authorization for chiropractic/PT/OT/ST for Medicare Advantage members (effective 9/1/2024; initial evaluation exempt, the ongoing treatment plan/visit count needs review, with reviews delegated to Optum via the UHC Provider Portal/Optum systems).
• CARELON (formerly AIM Specialty Health) — Anthem Blue Cross and Blue Shield of Georgia uses Carelon Medical Benefits Management to administer prior authorization / clinical-appropriateness review for physical/occupational/speech therapy and chiropractic on many Anthem products (the claim still goes to Anthem, but the AUTH/clinical review goes to Carelon). Always verify on the member’s card/portal whether chiropractic is carved out to ASH or whether auth runs through Optum or Carelon, because that determines where authorizations and claims go; delegation arrangements change by plan/product/year, so re-confirm.

What trips up chiropractic billing in Georgia:

• GEORGIA INSURANCE ‘EQUALITY’ STATUTE — O.C.G.A. 33-24-27 requires that accident-and-sickness policies covering a service within a chiropractor’s lawful scope must reimburse that service whether it is rendered by an MD or by a licensed Georgia chiropractor (a non-discrimination/equal-reimbursement mandate); it does NOT, however, force coverage of services a plan doesn’t otherwise cover, set rates, or override Medicare/Medicaid program rules.
• GEORGIA MEDICAID DOES NOT COVER ADULT CHIROPRACTIC — chiropractic is not a covered Medicaid benefit for adults in Georgia; the only route is for members UNDER 21 via EPSDT when a service is medically necessary and documented, and the CMOs administer that tightly. Do not assume a Medicaid card means chiropractic is payable.
• COMMERCIAL VISIT CAPS / MEDICAL-NECESSITY — the dominant Georgia commercial payers (Anthem BCBS Georgia, UnitedHealthcare, Aetna, Cigna) generally cover spinal manipulation (98940-98942) only when medically necessary for an active neuromusculoskeletal condition under a documented WRITTEN treatment plan with periodic re-evaluation; ‘maintenance’/supportive care is typically not reimbursable; many plans impose ANNUAL VISIT CAPS (commonly ~20-30 chiropractic/therapy visits per year, plan-dependent) and unit/code caps per date of service; extra-spinal manipulation (98943) and therapy modalities/exercise codes (97xxx) often need the correct modifiers (e.g., -59/-XS for distinct services, GP for PT plan of care) and may be denied as not separately payable.
• PRIOR-AUTH / DELEGATION QUIRKS — Anthem routes chiropractic/therapy clinical review through Carelon (ex-AIM); Cigna chiropractic is frequently delegated to ASH (send auth/claims to ASH, not Cigna); UHC Medicare Advantage now requires prior auth (via Optum) for the chiropractic treatment plan after the exempt initial eval — sending these to the wrong entity is a leading denial cause.
• MEDICARE — spinal CMT (98940-98942) must carry the AT modifier for active/corrective treatment; routine ‘maintenance’ manipulation is non-covered (bill with GA/GZ as appropriate and an ABN); X-ray is no longer required to demonstrate subluxation but documentation must support it.
• WORKERS’ COMP — treatment must be by the Authorized Treating Physician (panel of physicians or WC-certified MCO); chiropractors can be ATPs/panel members, but pre-authorization (Form WC-205) and Board Rule 205 documentation are essential, and billing follows the GA WC Fee Schedule.
• MVA — since Georgia has no PIP, chiropractic MVA care is paid by MedPay (up to limits, 3-year window), the patient’s health plan, or on a third-party lien/letter-of-protection basis at settlement; under SB 168 (2023) chiropractors now have statutory lien rights but must bill health insurance first. Not legal advice — verify benefits and current rules per payer.

Largely contract/payer-set, NOT fixed by a Georgia statute. The common initial-claim filing window for commercial/private payers in Georgia runs roughly 90-180 days from the date of service (many Anthem BCBS Georgia, UnitedHealthcare, Aetna and Cigna commercial plans use ~90, 120, or 180 days; some allow up to 365 days — confirm the exact number in your participating-provider agreement or the payer’s provider manual, since it varies by plan and product and can be shorter or longer).

Georgia context: the state’s prompt-pay law — O.C.G.A. 33-24-59.5 (the ‘timely payment of health benefits’ statute, plus the broader Insurance Delivery Enhancement Act / HB 1234 framework at O.C.G.A. 33-24-59.14) — governs how fast the INSURER must adjudicate/pay a CLEAN claim (generally pay or deny within 15 working/business days for electronic clean claims and 30 calendar days for paper clean claims, with 12% per annum interest on amounts not timely paid); it does NOT set the provider’s SUBMISSION deadline, which remains contractual.

Note: a fully-insured commercial plan governed by Georgia law differs from a self-funded ERISA plan (where federal law and the plan document control) — verify which applies.

Federal limit: generally 12 months (one calendar year) from the date of service to submit an initial Medicare fee-for-service (Part B) claim. This is set by the Social Security Act (Sec. 1842(b)(3)(B)) and CMS in the Medicare Claims Processing Manual (Ch. 1), not by Georgia.

Medicare Advantage plans set their own contractual filing deadlines (often up to ~12 months, sometimes shorter) — confirm per plan. (For chiropractic specifically, Medicare covers only manual manipulation of the spine to correct a subluxation, 98940-98942, and requires the AT modifier for active/corrective treatment — see payerNuance.)

Georgia Medicaid is a SIX-MONTH (180-day) state: initial claims must be received within six

• months from the date of service, per the Georgia Department of Community Health (DCH) Part I Policies and Procedures Manual (timely-filing provisions; failure to file within six months results in denial). This applies to traditional fee-for-service Medicaid and is mirrored by the Georgia Families CMOs/managed-care plans (CareSource, Peach State Health Plan, Amerigroup/Wellpoint, Humana CareSource) — e.g., Peach State’s HB 1234 guide: ‘All claims must be received by the plan within six
• months from the date the service was provided… Claims received after this time frame will be denied for failure to file timely.’ Key sub-rules typically follow the HB 1234 / statewide framework: timely RESUBMISSION/correction is within six months of the month of service OR three months of the month of denial, whichever is later; COB/third-party claims must be received within 180 days of the primary carrier’s EOP but never more than 12 months from the month of service; provider claim APPEALS are due within ~30 days of the EOP date (verify each CMO’s exact appeal window). Confirm the precise number against the live DCH Part I manual and the specific CMO — and note Medicaid is the payer of last resort.

Georgia Workers’ Comp: providers must submit medical bills within ONE YEAR of the date of service. The Georgia State Board of Workers’ Compensation ‘Best Practices Guidelines for Medical Providers’ states: ‘All bills must be submitted by the medical provider within one year of the date of service (see O.C.G.A. 34-9-203).’ Related rules: the employer/insurer/self-insurer must PAY the provider within 30 days of receiving the bill, and if not paid within 30 days O.C.G.A. 34-9-203 imposes penalties; provider fee/payment APPEALS (e.g., over reimbursement amount) must be made within 120 days from receipt of payment and/or the EOB; documentation of services (office/operative notes) is REQUIRED under Board Rule 205, and no provider may collect fees unless the reports required by the Board have been made.

Reimbursement follows the Georgia WC Fee Schedule. Separately, treatment must be by an Authorized Treating Physician (panel/MCO), and pre-approval of treatment/testing uses Form WC-205 (the insurer must respond within 5 business days or the request stands pre-approved).

Confirm each carrier’s specifics.

Georgia is a FAULT/tort state — it has NO mandatory PIP/no-fault (Georgia repealed no-fault decades ago); Personal Injury Protection is not sold, and first-party auto medical coverage is optional MedPay (Medical Payments). There is therefore NO short statutory ‘days-from-service’ bill-submission deadline like a PIP state has; submission timing is governed by the auto policy’s terms (file/notify promptly per the policy) plus a key statutory outer limit:

O.C.G.A. 33-34-3 provides that MedPay covers reasonable/necessary medical expenses for services rendered WITHIN THREE YEARS from the date of the accident (the insurer may allow a longer period). Practical norms: bill MedPay and/or the patient’s health insurance promptly; for the third-party (at-fault driver’s) liability claim, the underlying bodily-injury tort claim is bound by Georgia’s TWO-YEAR personal-injury statute of limitations (O.C.G.A. 9-3-33).

IMPORTANT 2023 change: Georgia’s hospital/medical lien law (O.C.G.A. 44-14-470 et seq., as amended by SB 168, eff. 7/1/2023) now expressly lets CHIROPRACTORS assert a lien against an injury recovery — but providers must first submit bills to the injured person’s health insurer before enforcing the lien.

Confirm each policy’s notice/proof-of-claim terms.
