Orthopedic Billing Services in Texas

Texas Medicaid orthopedic volume splits across three managed care programs. STAR+PLUS covers adults with disabilities and dual-eligible seniors — the population for total knee (27447) and total hip (27130) arthroplasty when authorized as medically necessary. STAR covers pregnant women, low-income parents, and children with conditions that may require pediatric orthopedic intervention; STAR Kids serves children with disabilities, including those with congenital orthopedic conditions. Each MCO — Superior HealthPlan, Molina Healthcare, UnitedHealthcare Community Plan, Wellpoint (the plan Texas billers still call Amerigroup; Elevance rebranded Amerigroup Texas to Wellpoint Texas on January 1, 2024), Community Health Choice — has its own orthopedic prior auth pathway. Joint replacement requires medical necessity documentation referenced against MCO-specific criteria (typically failed conservative care, imaging confirming end-stage osteoarthritis, BMI documentation). Texas Medicaid is tight on the calendar: the Texas Medicaid Provider Procedures Manual states that, unless otherwise stated, claims must be received by TMHP within 95 days of each date of service, and managed care runs the same 95 days (365 days applies only to out-of-state providers; the federal 12-month outer limit still applies to everyone). Commercial payers in Texas typically run 95-180 days. Verified against the TMPPM claims filing chapter at tmhp.com on 17 September 2026. We build per-MCO orthopedic templates: Superior's portal for STAR+PLUS arthroplasty auth, Molina's separate documentation requirements for arthroscopy, and UnitedHealthcare Community Plan's medical necessity bar for elective procedures.

BCBSTX is the dominant commercial orthopedic payer in Texas. Like most large national plans, BCBSTX outsources orthopedic procedure prior authorization to eviCore healthcare and Carelon Medical Benefits Management (formerly AIM). The list of pre-auth codes is long: 27447 (TKA), 27130 (THA), 29881 and 29827 (arthroscopic procedures), spinal fusion codes (22612, 22633, 22845), shoulder arthroplasty (23472), and most advanced imaging (MRI of any joint, 73721 and similar). eviCore reviews against MCG or InterQual criteria — failed conservative care for at least 6 weeks (sometimes 12), imaging confirming structural damage, functional impairment documentation. We submit auth requests with the full clinical narrative — presenting symptoms, prior conservative treatment (PT, NSAIDs, injections), imaging findings, ICD-10 diagnoses — referenced to the criteria. Peer-to-peer review is available within 14 days of an adverse determination. We track auth status in real time so scheduling doesn't run ahead of approval.

Place of service drives orthopedic reimbursement in Texas. The same procedure billed at POS 11 (office), POS 22 (hospital outpatient), or POS 24 (ambulatory surgery center) reimburses very differently — and audit risk follows place-of-service mismatches. Office-based 20610 (major joint injection) is straightforward at POS 11. Knee scope with meniscectomy (29881) typically runs in an ASC at POS 24 or hospital outpatient at POS 22, with very different facility fees and bundling implications. Total knee (27447) and total hip (27130) historically ran at POS 22; CMS removed both from the inpatient-only list in recent years, so ASC-based primary TKA and THA are now possible for low-risk patients — and in Texas, ASCs in Houston, Dallas, and Austin have built TKA-in-ASC programs. Each payer treats ASC TKA differently: BCBSTX and Aetna pay it, Texas Medicaid MCOs typically still require hospital outpatient. Place-of-service discipline (POS code, facility NPI, supervising physician) is critical.

27447 (total knee arthroplasty) and 27130 (total hip arthroplasty) are the highest-revenue elective orthopedic codes in Texas. Both require prior auth from BCBSTX, Aetna, UnitedHealthcare, and Cigna in the commercial market, and from each Texas Medicaid MCO. Documentation requirements include conservative care trial, imaging, BMI (some MCOs flag BMI > 40), and surgical risk assessment. 29881 (knee arthroscopy with meniscectomy) and 29827 (shoulder arthroscopy with rotator cuff repair) need conservative care documentation and prior MRI. 20610 (major joint arthrocentesis) is reimbursed at office, hospital outpatient, and ASC settings, with HCPCS J-code for the injectable (J3301 for triamcinolone, J7321 for hyaluronic acid). 20680 (hardware removal) reimbursement varies by anatomic site and complexity; we document the body region and approach for clean adjudication. Modifier discipline matters: -50 for bilateral procedures, -RT/-LT for laterality, -78 for related return to OR, -79 for unrelated procedure during postop period.

The Texas prompt-pay clock turns on how the claim was submitted, not on what kind of plan received it. Insurance Code 843.338 requires a health maintenance organization to determine and pay a clean claim from a participating physician not later than the 45th day after receipt of a non-electronic claim or the 30th day after an electronically submitted one, and Section 1301.103 imposes the identical deadline on preferred provider benefit plans. An orthopedic practice that has calendared an HMO clock and a PPO clock has been tracking a distinction the statute does not make. The penalty is not a flat interest rate either. Section 843.342, and Section 1301.137 on the preferred provider side, make a late payer owe the contracted rate plus the lesser of 50 percent of the difference between billed charges as submitted and the contracted rate, or $100,000; the lesser of 100 percent of that difference or $200,000 if the claim is paid on or after the 46th day and before the 91st; and, on or after the 91st day, that penalty plus 18 percent annual interest on it. The penalty is computed off billed charges, which is why the charge master matters on a TKA (27447) claim carrying a professional fee and a far larger facility component. Statutory text verified against statutes.capitol.texas.gov on 17 September 2026. We track every clean claim against the date and format of receipt, flag stalled payments before the applicable deadline, and file TDI prompt-pay complaints when payers default.

Texas is the only state where workers' compensation insurance is optional for private employers (about 28% of Texas private employers don't carry coverage as of recent Texas Department of Insurance reporting). For orthopedic practices, that means a meaningful share of work-related injury patients arrive with one of three coverage realities: covered by the Texas Workers' Compensation system through the Texas Department of Insurance Division of Workers' Compensation (DWC), covered by a non-subscriber employer's alternative plan (which behaves more like commercial), or uncovered (patient liability). Texas DWC bills against the official medical fee guidelines and uses preauthorization for specified codes (most surgical orthopedics, advanced imaging, spinal injections beyond a threshold). The CompTPA designated treating doctor (DTD) and required medical examiner (RME) workflows differ from commercial; we manage the documentation, work status reports, and DWC-73 forms separately from the commercial workflow.
