Specialty Medical Billing

Cardiology is one of the most procedure-dense and payer-scrutinized specialties in medicine. Interventional cardiology, electrophysiology, nuclear cardiology, and echocardiography each carry unique CPT families, global period rules, and payer-specific reimbursement policies that differ dramatically from standard E/M billing.

Cardiology billing errors most commonly occur in three areas: incorrect global period management for procedural follow-up visits, missed or incorrect modifier application for multiple procedures on the same date of service, and inadequate documentation to support the level of E/M service billed during complex chronic care management. Our cardiology billing specialists are trained specifically in cardiac CPT families — catheterization codes (93451–93572), echocardiography (93303–93356), electrophysiology (93600–93662), stress testing (93015–93018), and pacemaker/ICD codes — so every procedure is coded precisely and every reimbursable service is captured.

Orthopedic billing combines the complexity of surgical coding with the high-volume E/M demands of a busy office practice. From fracture care and joint replacement to sports medicine injections and spine surgery, orthopedic practices face a unique set of billing challenges that generalist billing teams consistently undermanage.

The most costly orthopedic billing mistakes involve surgical global periods. Medicare and most commercial payers assign 10-day or 90-day global periods to surgical procedures, during which follow-up visits are bundled into the surgical payment. Billing a separate E/M during the global period without the correct modifier results in automatic denial — and failing to append modifier 24 or 25 when billing is legitimately separate leaves money on the table. Our orthopedic billing specialists manage global period tracking for every provider in your practice, ensuring compliant billing of post-operative care while capturing every separately billable service. We also manage the high prior authorization burden of orthopedic surgery — joint replacement, spine surgery, and diagnostic imaging all require pre-approval from most commercial payers — and our 94%+ auth approval rate keeps your surgical schedule moving.

Family medicine and primary care practices bill the highest volume of E/M codes in medicine — and face the greatest scrutiny for E/M level selection. Undercoding is endemic in primary care: studies show that primary care physicians undercode their E/M levels by 20–30% due to documentation habits that underrepresent the complexity of care actually delivered.

The 2021 E/M guideline revision fundamentally changed how office visit levels are determined, shifting from a three-key-component documentation framework to a Medical Decision Making (MDM) or total time basis. Many primary care practices have not adapted their documentation templates to the new guidelines, resulting in systematic undercoding that costs the average primary care physician $30,000–$60,000 annually in missed revenue. Healix RCM's family medicine billing team reviews your E/M coding patterns against the 2021 AMA guidelines, identifies systemic undercoding, and works with your clinical team to implement documentation practices that support accurate level selection without increasing documentation burden. Beyond E/M, primary care billing complexity includes Chronic Care Management (CCM) and Principal Care Management (PCM) monthly billing, Annual Wellness Visit (AWV) vs. preventive visit vs. problem-focused visit distinction, and behavioral health integration billing under Collaborative Care Model codes.

Behavioral health billing has unique challenges that make it one of the most error-prone specialty areas in medical billing. The carve-out payer structure — where behavioral health benefits are managed by a separate company from the medical benefits — means that eligibility, authorization, and claims must be directed to a completely different entity than the patient's medical insurance. Missing this distinction results in systematic denials that are difficult to recover from.

Healix RCM's behavioral health billing specialists understand the full landscape of behavioral health payer relationships, including the major carve-out payers (Beacon Health Options, Magellan, ValueOptions, OptumBH), managed care behavioral health plans, and state Medicaid behavioral health carve-outs. We manage authorization tracking for every treatment episode, verify behavioral health benefits separately from medical benefits, and apply appropriate telehealth modifiers (95, GT, FQ) for teletherapy sessions. The Mental Health Parity and Addiction Equity Act (MHPAEA) entitles patients to behavioral health coverage on equal terms with medical coverage — but payers routinely violate parity in practice. Our team identifies parity violations in authorization denial patterns and pursues parity appeals on your behalf, recovering coverage that patients are legally entitled to.

Physical therapy and occupational therapy billing operates on a units-based system that is fundamentally different from physician billing. Every timed therapeutic procedure code (therapeutic exercise, neuromuscular re-education, manual therapy, ultrasound) is billed in 15-minute units, and the 8-minute rule governs when a unit can be billed for a timed service — creating a complexity that requires precise treatment time documentation for every visit.

Medicare's therapy cap has been replaced by the KX modifier threshold — requiring the KX modifier once therapy costs exceed $2,230 annually to certify medical necessity for continued treatment. Above the threshold, claims are subject to medical review, and inadequate documentation of functional improvement is the most common reason for post-payment audit recoupment in PT/OT practices. Our therapy billing team works with your providers to ensure treatment notes document functional outcomes in measurable terms — not just what treatment was performed, but the patient's response and progress toward functional goals. Beyond Medicare, we manage the full commercial payer landscape for PT/OT including prior authorization management, plan of care tracking, and denial appeals with functional outcome documentation.

Emergency medicine billing combines the highest E/M code volumes in medicine with the greatest documentation complexity. ED E/M codes (99281–99285 and critical care 99291–99292) require precise differentiation based on MDM or physician time — and the acuity-based nature of emergency care means that the same presenting complaint can legitimately support any level depending on what the physician found and decided.

The most significant revenue leak in emergency medicine is systematic E/M downcoding driven by documentation that does not capture the complexity of the care actually delivered. Emergency physicians are notoriously pressed for time and often document in shorthand that supports lower E/M levels than the patient's acuity warranted. Our ED billing specialists are trained in the 2023 CPT E/M revisions for ED codes and work with your physician group to implement documentation templates that capture MDM complexity — the number and nature of problems addressed, the amount and complexity of data reviewed, and the level of risk — in a format that clearly supports high-level billing. We also manage facility vs. professional billing splits for hospital-based emergency groups, critical care time documentation (including interruptions that toll the clock), and procedure billing for ED interventions including laceration repair, fracture management, and lumbar puncture.
