Allergy & Immunology billing · Charleston, SC
247 Medical Billing Services provides allergy and immunology billing services in Charleston built around the one truth that decides an allergy practice's revenue: the antigen line, not the office visit, is where you get paid or audited.
Serving allergists across Charleston County and the wider Lowcountry since 2005, our team treats your mixing log, your skin-test counts, and your biologic authorizations as the core of the claim, because in this specialty they are.
We lead with denials because the fastest money in allergy billing is the money you never lose. The most-audited line in the specialty is antigen preparation, so that is where our scrubbing is tightest, and every edit below runs before submission rather than after the remittance.

Running these edits on the front end is what produces up to 40% fewer denials and up to 90% recovery on anything that still slips through, and it is why Palmetto audits do not rattle the practices we serve.
Once the denials are engineered out, the claim itself follows a fixed, audit-ready path from eligibility to posted payment.
| Stage | What happens | Who owns it |
|---|---|---|
| Eligibility + benefit routing | Healthy Connections / commercial / Medicare verified; biologic sent to medical vs. pharmacy benefit | 247 MBS + front desk |
| Prior authorization | Biologic and non-covered testing authorized before service | 247 MBS |
| Charge capture | Skin tests counted per test; antigen prep read from the mixing log | 247 MBS coders |
| Prep vs. administration split | Antigen-prep line and injection-administration line billed separately | 247 MBS coders |
| Modifier review | Distinct same-day E/M flagged only when documentation supports it | AAPC/AHIMA coders |
| Clean-claim submission | Claim scrubbed and filed within 24 hours | 247 MBS |
| Payment + denial posting | Remittance posted; short-pays worked the same cycle | 247 MBS A/R team |
That discipline is how we hold a 99% first-pass clean-claim rate and keep days in A/R under 25 for Lowcountry allergists.
Allergy and immunology revenue is unit-driven and buy-and-bill-driven, which makes it unlike almost any other office-based specialty. Skin and intradermal testing is reported per individual test performed, with units set to the number of tests and held inside each payer's annual cap and MUE ceiling. Bill the panel as one unit and every patient is underpaid; ignore the cap and the overage is denied.
Antigen preparation is billed from the mixing log at one cc per dose, with ten billable doses per multidose vial under the Medicare dosing convention, and venom immunotherapy counted by the number of venoms rather than the vial. The preparation service and the injection-administration service are distinct line items: the injection is billed once for two or more shots on the same day and never multiplied, and the antigen line appears only when your practice actually prepared the extract. A Charleston billing company that cannot read a mixing log the way Palmetto does will cost you more than it saves.
Biologics for severe asthma and chronic urticaria carry the highest single-error cost. On a thirty-thousand-dollar-a-year drug the HCPCS unit math must be exact, the discarded-drug modifier must sit on every single-dose vial, and prior authorization must be confirmed before the dose is drawn up. Medical billing for allergy and immunology in Charleston that skips the verification of benefits and medical-versus-pharmacy benefit check turns a paying drug into a write-off.

The reason practices outsource allergy and immunology billing in Charleston is rarely cost alone; it is risk concentration. When antigen reconciliation and biologic authorization live in one in-house biller's head, a single vacation stalls the buy-and-bill revenue and a single misread mixing log invites a recoupment. Outsourcing allergy and immunology billing services in Charleston to a dedicated specialty team removes that fragility and replaces it with a bench of professional, credentialed coders.
As an allergy and immunology billing company working this specialty since 2005, we bring a ~99% net collection rate, 24-hour submission, and 98% client retention, with no lock-in and a clean, benchmarked handoff. Choosing our allergy and immunology billing services outsourcing in Charleston converts an audit-exposed, unpredictable revenue stream into a managed one. As a medical billing services company, we back every engagement with HIPAA and SOC 2 Type II compliance, HBMA membership, and AAPC and AHIMA credentialed coders.
You can read our full allergy and immunology billing overview or see how we support allergy and immunology billing in South Carolina statewide. Our prior authorization services and eligibility verification plug straight into the biologic and buy-and-bill side of your workflow.
Our allergy and immunology billing services provider team supports the full Charleston-market range: solo and group allergists, pediatric and adult allergy clinics, high-volume skin-testing and shot suites, immunotherapy clinics billing incident-to, severe-asthma and biologic infusion programs, and food-allergy and oral immunotherapy practices. Whether you operate near the MUSC medical district downtown or run satellite shot clinics out toward Mount Pleasant and West Ashley, the antigen and administration rules are identical, and so is our attention to them.
Every client works with a dedicated account manager who knows the Healthy Connections and Palmetto rulebooks, plus a free 360-degree reporting dashboard showing clean-claim rate, A/R aging, and denial trends in real time. Charleston's mix of established downtown groups and fast-growing suburban satellites means no two of our clients bill the same way, and we build each practice's edits, fee schedule, and immunotherapy workflow around its own patient panel rather than a one-size template.
The Lowcountry's steady population growth has pushed allergy demand up sharply, and with it the volume of skin testing, seasonal immunotherapy build-ups, and biologic starts a single practice runs in a quarter. That volume is exactly what makes a disciplined billing partner pay for itself: at scale, a fraction of a percent of misread antigen units or missed authorizations becomes real money. We measure that leakage on your baseline, close it, and report the recovered dollars back to you every month, so the value of the partnership is never a matter of guesswork or a promise you cannot audit.
Charleston allergists keep more of what they earn when the antigen and biologic lines are billed to the letter, and that precision is what we deliver. 247MBS handles medical billing for allergy and immunology in Charleston as an audit-first discipline — reading Palmetto GBA's Jurisdiction M edits, verifying Healthy Connections and commercial benefits, and tying every antigen unit to the mixing log before a claim posts. Practices from the MUSC district to Mount Pleasant and West Ashley see faster, cleaner payment through peak Lowcountry pollen seasons. We have run specialty revenue since 2005 under HIPAA and SOC 2 Type II controls, holding a 99% first-pass clean-claim rate and days in A/R under 25. Request a revenue review to find your leak points.

Allergy & Immunology billing services in South Carolina — the payer programs, authorities and rules behind every Charleston claim.
The national Allergy & Immunology Billing Services — the codes, unit rules and denials without the local layer.
Yes. We verify the member's South Carolina Medicaid managed-care plan, confirm immunotherapy and biologic authorization rules, and count antigen and testing units to the plan's cap before the claim is filed.
Every antigen unit is tied to your mixing log at one cc per dose under the Medicare dosing convention. If the log will not support the units, the line does not go out, which is the single best defense in a Jurisdiction M review.
Yes. We confirm prior authorization and medical-versus-pharmacy routing before administration, apply the discarded-drug modifier on single-dose vials, and reconcile the HCPCS units against what was actually administered.
Most practices go live within a few weeks. We baseline your clean-claim rate and A/R, then run parallel until your first clean cycle confirms the lift, with your account manager mapping every local contract up front.
From solo practices to multi-provider groups, we bill Allergy & Immunology for Charleston practices with a dedicated account manager, certified coders and a live dashboard — so the units, authorizations and appeals that decide your month stop being the thing nobody has time for.
