Expert Rheumatology Billing Services

We Fix Infusion Billing That General Billers Mess Up

You bought a $5,000 biologic. You did the infusion. Then the claim was denied for wrong units, missing JZ modifier, or expired prior auth. Now $5,000 is stuck in A/R past 90 days.

That happens a lot in rheumatology.

SwiftCare Billing assigns rheumatology claims to a dedicated rheumatology billing team. We know buy-and-bill, J-codes, NDCs, unit conversion, admin codes 96413 to 96417, and JW/JZ modifiers. So your infusion claims get paid right the first time.

Built for private rheumatology practices and in-office infusion centers in all 50 states.

Rheumatology Medical Billing Services for Private Practices and Infusion Centers

We provide Rheumatology Medical Billing Services for practices that want specialty billing, not generic RCM. We work as a Rheumatology Medical Billing Company for Private Practices.

Private Rheumatology Practices

You have 1 to 5 providers. You do RA, PsA, lupus, gout, AS, osteoporosis. You need Rheumatology Practice Billing Services that code to specificity, not M06.9 for everything.

Group Practices and Multi-Provider Clinics

Multiple providers and locations. We manage billing by provider and location. Collections by provider, A/R aging by location, denial rate by payer.

In-Office Infusion Centers and Buy-and-Bill Practices

This is where most money gets lost. Buy-and-bill means you you buy the drug, store it, infuse it, and bill it. You need correct J-code to NDC mapping, unit conversion, admin codes 96413 to 96417, wastage documentation.

We bill Remicade J1745, Inflectra Q5103, Orencia J0129, Rituxan J9312, Simponi Aria J1602, Benlysta J0490, Krystexxa J2507 daily.

Hospital Outpatient Rheumatology Clinics

Hospital outpatient needs correct place of service, revenue codes, and sometimes UB-04. We handle that compliance.

Pediatric and Autoimmune Specialty Clinics

Weight-based dosing for kids, juvenile arthritis. Dose changes by weight, so units and wastage change. We check MAR and inventory before billing.

Where Rheumatology Practices Lose Revenue on Biologics and Infusions

The problem is not that payers refuse to pay. It is small mistakes made before the claim goes out.

Prior Authorizations That Expire Before the Infusion Date

Auth approved for 6 months, 8 doses. Patient comes for 9th dose in month 7. You infuse, claim denies for no auth. We track auth start, end, units approved, units used, and send alert 14 days before expiry.

J-Code, NDC, and Unit Mismatches That Trigger Denials

This is the biggest denial reason. J1745 is 10mg per unit. If you infuse 400mg Remicade, you must bill 40 units. If you bill 1 unit, you lose $4,000. Also NDC must be 11-digit and must match vial actually used from inventory.

Missing JW and JZ Modifiers for Drug Wastage

Medicare Part B now requires JZ modifier when there is zero wastage from single-use vial. If there is wastage, JW modifier with wasted amount on separate line. Since October 1, 2023, Medicare returns single-dose drug claims that are missing JW or JZ.

Medical Necessity Denials for High-Cost Biologics

You billed biologic with M06.9, payer wanted M05.79 and proof patient failed methotrexate for 3 months. Without proper linkage and clinicals, high-cost drug denies.

Underpaid Infusion Claims Billed Without Drug Administration Codes

You billed J-code for drug but forgot 96413 for first hour IV infusion and 96415 for additional hour. That is $180 to $350 lost per infusion.

Infusion Claims Sitting in A/R Past 90 Days

An office claim is $150. An infusion claim is $5,000. If it sits past 90 days and hits timely filing limit for MA plans, loss is huge. We work high-dollar claims first, not alphabetical.

Why General Billing Fails at Infusion Billing

Billing Step	What General Biller Does	What Rheumatology Specialist Does
J-Code Units	Bills 1 unit for any dose	Converts dose to correct units. 400mg = 40 units
NDC Mapping	Uses same NDC for all claims	Maps 11-digit NDC from actual vial used
JW/JZ Modifiers	Skips JW/JZ, claim returns	Bills JW for wastage, JZ for no wastage
Admin Codes	Bills only J-code for drug	Bills J-code + 96413 + 96415
Prior Auth Tracking	Does not track auths; infuses without one	Tracks auth dates, units, expiry, re-auth

Our Rheumatology Coding and Billing Services

Our Rheumatology Coding and Billing Services are done by Rheumatology billing specialists. This also covers complete Rheumatology coding services.

Eligibility and Benefit Investigation for Biologics

Before infusion, we check if drug is covered under medical benefit or pharmacy benefit. What is deductible left? Coinsurance? Site of care restriction? Patient responsibility known before infusion.

Prior Authorization and Medical Necessity Documentation

We submit prior auth with ICD-10, CPT, J-code, dose, frequency, previous therapy failure, labs, disease activity score if needed.

HCPCS J-Codes, CPT Administration Codes, and NDC Mapping

We map every drug properly. Remicade’s NDC 57894-030-01 to 57894-0030-01, dose 400mg = 40 units of J1745. We put NDC in 2410 loop with N4 qualifier, unit UN, and price.

JW and JZ Modifier Compliance for Drug Wastage

We check inventory log and MAR. 100mg vial, dose 80mg, wastage 20mg. Bill 80mg one line, 20mg with JW second line with documentation. If no wastage, JZ added for Medicare.

ICD-10 Coding for Rheumatoid Arthritis, Psoriatic Arthritis, and Lupus

We code to specificity. M05.79 RA with rheumatoid factor, M07.60 enteropathic, L40.50 psoriatic, M32.10 SLE, M45.9 AS. Specific code helps medical necessity.

Modifier 25, 59, and 95 Usage for Rheumatology E/M

If E/M and infusion same day and separate, we use modifier 25 only when payer allows and documentation supports. For telehealth follow-up, 95 modifier and POS 10.

Rheumatology Claims Billing Services From Submission to Payment

Our Rheumatology claims billing services cover first submission to final payment.

Clean Claim Scrubbing for Rheumatology Edits

We have rheumatology-specific edits: J-code vs NDC vs units, missing admin code, missing JW/JZ, diagnosis not matching LCD, missing referring provider, timely filing risk.

Medical Benefit Claim Submission: CMS-1500 and 837P

Almost all rheumatology infusions go on medical benefit, not pharmacy. We submit on CMS-1500 / 837P with correct POS 11, rendering provider, taxonomy, NDC loop.

Rejection Triage Within 24 Hours

If clearinghouse rejects for NDC format, NPI mismatch, invalid J-code, we fix within 24 hours. Not next week.

Infusion Claim Status Tracking by Payer

We track every high-dollar claim daily. Did it go to medical review? Does payer need invoice, MAR, waste log? We send same day.

Rheumatology Insurance Billing Services for Commercial and Government Payers

Payer rules for biologics are completely different. Our Rheumatology insurance billing services handle that.

Commercial Payer Rules: BCBS, Aetna, Cigna, UHC

BCBS may need auth through Carelon, UHC through Optum, Aetna through CVS Caremark Specialty. Some require white bagging vs buy-and-bill. We confirm before infusion.

Medicare Part B and Part D Infusion Rules

Part B covers office infusions under incident-to rules if supervision met. Part D does not cover office infusions. Many practices bill Part D by mistake.

Medicare Advantage and Prior Auth Variations

MA plans follow Medicare LCDs but use their own auth portals and often have shorter timely filing limits than Original Medicare’s 12 months.

State Medicaid and Managed Medicaid Billing

Medicaid needs NDC, invoice, manual pricing. Managed Medicaid like Fidelis, Healthfirst, Anthem have different forms.
