Medical Billing by Specialty

We bill for a wide range of specialties (see who we help). These are the specialties practices most often bring to us, and what we do differently for each.

Cardiology billing

Cardiology claims depend on prior authorization and clean documentation. We secure and track authorizations for cardiac catheterization, echocardiography, nuclear stress testing and advanced imaging before the service date, bill pacemaker and ICD device checks and remote monitoring on the right schedule, and split professional and technical components correctly for in-office and hospital-based studies.

OB/GYN billing

Maternity coding is changing. The AMA has restructured maternity care coding effective January 1, 2027 (per the AMA): the traditional global obstetric package gives way to separate reporting for antepartum care, labor management, delivery and postpartum care. We are preparing OB/GYN practices for the transition, including pregnancies that span the change-over, alongside gynecology, in-office procedures and ultrasound.

Neurology billing

Neurology revenue leans on diagnostic testing that payers scrutinize closely. We bill routine and long-term EEG, EMG and nerve conduction studies, and in-lab and home sleep studies with the medical-necessity documentation payers expect, manage authorizations for testing and infusion therapies, and code complex visits for epilepsy, migraine, multiple sclerosis and movement-disorder patients.

Mental health billing

Behavioral health has its own rulebook. We track Medicare, state Medicaid and commercial telehealth requirements — place-of-service codes, modifiers, audio-only allowances and any in-person visit conditions — and bill psychotherapy time, add-on services, psychiatric evaluations and collaborative care correctly for psychiatrists, psychologists, LCSWs and LPCs, with each clinician credentialed on the plans they need.

Internal medicine billing

Internal medicine means high visit volume and complex, chronic patients. We code visits to the documentation, capture annual wellness visits, chronic care management, transitional care management and remote patient monitoring where the requirements are met, and keep Medicare Advantage and commercial plan rules straight when preventive and problem-oriented services happen on the same day.

Family practice billing

Family medicine spans newborns to seniors, so one workflow has to handle well-child visits, vaccine administration, preventive exams, same-day sick visits, minor procedures and chronic care. We keep preventive-versus-problem visit coding clean, bill vaccine products and administration under the right program rules, and follow up on the small-balance denials that quietly add up.

Urgent care billing

Urgent care runs on speed and volume. We verify eligibility at check-in, code visits and on-site procedures, X-rays, labs and injections quickly, handle occupational medicine and workers’ compensation claims separately from health plans, and work payer-specific urgent care rates and place-of-service rules so high-volume clinics are not buried in denials.

Pediatric billing

Pediatric billing mixes preventive schedules, vaccines and Medicaid managed care. We bill well-child visits, developmental and behavioral screenings, vaccine administration and same-day sick visits correctly, and we work Medicaid and CHIP managed-care claims in each state, with the eligibility checks and authorizations those plans require.

Multi-Specialty Groups

Multi-specialty groups often end up with one biller per specialty and a separate credentialing vendor, and nobody sees the whole picture. AMS Solutions, Inc. runs billing and credentialing for the entire group from one roster, so every provider, location and specialty is tracked in one place.

• One roster across specialties. Each clinician’s NPI, taxonomy, licenses, CAQH profile, payer enrollments and expiration dates live in one list, owned by one team.
• Shared payer enrollment and effective dates. When a new physician joins, credentialing and billing work from the same effective dates, so claims are not sent before a provider is active with a plan.
• Consolidated reporting. Aging A/R, denials and collections, broken out by specialty, provider and location in one report.
• A single point of contact. A dedicated account representative coordinates the coders, billers and credentialing specialists working for your group.

Credentialing and Provider Enrollment in Every State

A claim for a provider who is not yet enrolled is a denial waiting to happen. Our credentialing and provider enrollment team handles initial credentialing, re-credentialing, CAQH upkeep and payer enrollment for practices in all 50 states. Each state adds its own steps. In Texas, for example, that means the Texas Standardized Credentialing Application used by state-regulated health plans, and Texas Medicaid enrollment through TMHP, which comes before contracting with a Medicaid managed-care plan (per TMHP). See Texas credentialing and provider enrollment for the details. Because the same team runs your billing, enrollment effective dates flow straight into claim scheduling.

Payers We Bill in Every State

• Medicare. We work claims, edits, redeterminations and provider enrollment with the Medicare Administrative Contractor for your jurisdiction — for example, Novitas Solutions, the Part A and Part B contractor for Jurisdiction H, which includes Texas (per CMS).
• Medicaid. We bill state Medicaid fee-for-service and managed-care plans. In Texas, for example, TMHP handles Medicaid provider enrollment and fee-for-service claims, and most benefits are delivered through managed-care programs such as STAR, STAR+PLUS and STAR Kids (per TMHP). See medical billing services in Texas for more.
• Commercial plans. Commercial, employer-sponsored and Medicare Advantage plans in every state, plus workers’ compensation for urgent care and occupational medicine.

• Medical credentialing & provider enrollment — payer enrollment and CAQH maintenance
