Claims Processed for California Providers
Gastroenterology is one of the most code-intensive specialties in medicine. Screening colonoscopies convert to therapeutic procedures mid-exam, endoscopy centers bill facility and professional claims separately, and payer rules change constantly. When billing falls behind, revenue leaks quietly. Here is where Arizona practices most often lose money.
Missing prior authorizations, mismatched screening and diagnostic coding, and eligibility errors send GI claims back unpaid. Every denial delays cash flow and costs staff time to rework, and many are never appealed at all.
Claims that sit unpaid past 60 or 90 days get harder to collect with every week. Without consistent follow-up, aging A/R quietly drains revenue from procedures you have already performed.
Payers often pay below contracted rates or bundle procedures incorrectly. Without contract-based payment review, these shortfalls go unnoticed and unrecovered.
Salaries, benefits, training, and turnover add up, yet in-house teams still struggle to keep pace with payer changes. Outsourcing turns a fixed overhead into a cost tied to performance.
Colonoscopy and endoscopy claims depend on precise CPT, ICD-10, and modifier selection. One misapplied code can turn a covered screening into a denied claim or an unexpected patient bill.
Biologic infusions, capsule endoscopy, and other GI services often need payer approval first. Slow authorizations push procedures back, frustrate patients, and put revenue at risk.
Arizona practices manage Medicare, AHCCCS health plans, and multiple commercial insurers at once. Each has its own rules, portals, and filing deadlines.
Find out exactly where claims are being denied, delayed, or underpaid. Our free billing audit reviews your recent claims, denials, and A/R and shows you what is recoverable, with no obligation.
Right On Time Billing manages your complete revenue cycle, from the first patient call to the final payment posted. As a full-service medical billing company, we replace scattered tasks and disconnected vendors with one accountable team. That means cleaner claims, fewer write-offs, and a clear view of your practice's financial health. Arizona practices can outsource medical billing entirely or add the specific services they need.
Our revenue cycle management (RCM) services work inside your existing EHR and practice management system. Each stage feeds the next, so errors are caught before they turn into denials.
Our medical billing and credentialing services keep providers enrolled and payable. We handle applications, CAQH profile maintenance, and payer re-credentialing so new physicians can bill sooner.
We request, track, and document authorizations for procedures, infusions, and imaging before the patient arrives, which prevents avoidable denials and last-minute cancellations.
Our billers prepare, scrub, and submit claims, then post payments and pursue every unpaid claim. Our medical billing and collection process keeps money moving instead of sitting in A/R.
We confirm active coverage, benefits, copays, and authorization requirements before each visit. Front-end accuracy is the cheapest way to prevent back-end denials.
Certified-quality coding for endoscopy, colonoscopy, and E/M visits supports accurate reimbursement and compliance. Practices that outsource medical coding gain specialty accuracy without adding headcount.
Combine billing, coding, credentialing, and prior authorization under one agreement. Our integrated medical practice billing services are tailored to how your practice actually runs.
A dependable medical billing process is a repeatable one. Every claim we handle follows the same seven steps, with quality checks at each stage and full visibility for your team through reports and portal access.
Verify available coverage and benefits info and identify issues early.
Review documentation and charges to support accurate coding.
Check claims for errors and missing info prior to submission.
Submit prepared claims and monitor progress through adjudication.
Post payments and remittances while keeping accurate account balances.
Investigate denials and aging claims with active payer follow-up.
Provide transparency into claims, collections, and overall activity.
Every metric is reported openly, so you always know how your revenue cycle is performing.
Billing in Arizona means working across several payer systems at once. Medicare claims are administered by Noridian Healthcare Solutions, while Arizona's Medicaid program, AHCCCS (the Arizona Health Care Cost Containment System), operates largely through managed care health plans, each with its own authorization rules, portals, and timely filing limits. Add commercial and Medicare Advantage plans, and it is easy for a claim to fall through the cracks. Our team manages these workflows every day, so yours doesn't have to.
Our Medicare billing services cover Part B claims, medical-necessity documentation, and correct screening and diagnostic coding for GI procedures. That protects patients from surprise costs and your practice from denials.
Our Medicaid billing services cover AHCCCS provider registration, health plan enrollment, eligibility checks, and claim follow-up across Medicaid health plans and programs.
We manage claims for major commercial payers, including contract-rate checks, prior authorization requirements, and appeals for underpayments.
From Medicare Advantage plans to TRICARE, workers' compensation, and tribal and Indian Health Service programs, we track each payer's rules so claims are filed correctly the first time.
Specialty care requires more than generic billing. Our teams understand specialty-specific coding, payer requirements, authorization triggers, and revenue cycle workflows to help keep claims accurate and moving toward payment.
Our specialty-focused billing support is built around your specialty's coding requirements, payer expectations, authorization needs, and revenue cycle priorities.
GI billing support for colonoscopy, endoscopy, ERCP, anesthesia, facility claims, and prior authorization workflows.
Billing support for home health agencies, with payer-specific workflows and documentation requirements handled by experienced billers.
Specialty-focused billing support for behavioral health providers, including session-based coding, telehealth claims, and authorization tracking.
Billing support for hospice providers, including election periods, level-of-care documentation, and payer requirements.
We support a wide range of specialties and can build a billing workflow around your practice's unique requirements.
Arizona physicians choose Right On Time Billing for three reasons: specialty depth, payer knowledge, and complete transparency. You get a dedicated team that knows your codes, your payers, and your numbers, backed by reporting you can check any time.
Arizona's healthcare landscape is unlike any other. Practices serve large Medicare populations, seasonal winter visitors with out-of-state coverage, rural and tribal communities, and a fast-growing commercial market. That mix makes payer coordination and eligibility verification more demanding than in most states.

EXCELLENT Based on 14 reviews Posted on Google Florence OparaTrustindex verifies that the original source of the review is Google. Right on Time Billing is a company dedicated to providing billing services with accuracy, reducing denials, and attention to increasing revenue. I will recommend them to any company that wants to reduce denials and increase revenue.Posted on Google Adele CauvinTrustindex verifies that the original source of the review is Google. I own a healthcare practice and we've been working with Right On Time Billing Services for about a year and a half now. Honestly, they've taken a huge weight off my shoulders. The best part is the communication it's always quick and clear, and I have one person to talk to instead of getting bounced around. Beyond just billing, they've become the people I go to when I need help with almost any part of running the practice. Whatever comes up, I can ask them and they'll point me to the best solution. They just know their stuff. If you run a practice and billing is stressing you out, I'd genuinely recommend them. Really glad we found them.Posted on Google Ruqayyah EjalonibuTrustindex verifies that the original source of the review is Google. I can’t thank Right On Time Billing Services enough! They have truly been God-sent. When other billing companies were unwilling to work with a new agency, Right On Time Billing Services came through after we found them on Google and walked us through every step of the setup process. They were incredibly patient, supportive, and knowledgeable throughout the entire process. From getting everything set up to helping us get our billing running smoothly, they were there every step of the way. I truly appreciate their dedication, professionalism, and willingness to work with us. If you’re a new agency looking for a billing company that will actually take the time to guide and support you, I highly recommend Right On Time Billing Services. Thank you for everything you do!Posted on Google Carolina StruveTrustindex verifies that the original source of the review is Google. I own a hospice, a home health agency, and a DME company in Texas, and Right On Time Billing Services has handled our billing since 2021. After 20+ years in this industry I've been through my share of billing companies, and these are the first ones I've never had to chase. What made me finally write this review: the NOAs. Anyone in home health or hospice knows a missed NOA can cost you real money, and in four-plus years that just hasn't been an issue with them. Claims go out clean, follow-up actually happens, and when I call, a person answers. They also handle our credentialing and coding, and honestly the biggest change for me is that billing stopped being something I think about. That's worth more than I can explain to anyone who hasn't run one of these agencies. They're local to Houston too — we've sat down face to face plenty of times, which you don't get with most billing companies anymore. Happy to recommend them to other home health and hospice owners.Posted on Google Carmela RonquilloTrustindex verifies that the original source of the review is Google. Excellent billing company! Professional, responsive, and easy to work with. They provide reliable service and great communication. Highly recommended.Posted on Google Angela MottonTrustindex verifies that the original source of the review is Google. We are using Right On Time Billing Services for about 3 years for our home health agency. Before them, chasing claims and authorizations took up way too much of our week. Now that's basically off my plate — authorizations get done without me having to follow up, and if I have a question there's an actual person I can call who knows our account. Payments come in faster than they used to and denials are way down. They also send us regular reports, so I'm never guessing where things stand. That was our biggest issue with billing before — just not knowing. No complaints after 3 years, which says a lot in this business.Posted on Google Jasmine EnriquezTrustindex verifies that the original source of the review is Google. I am truly grateful for my home care provider. They are compassionate, dependable, and always treat me with kindness and respect. They go above and beyond to make sure my needs are met, and they make a positive difference in my daily life. Their patience, professionalism, and caring heart are appreciated more than words can express. I feel supported and valued because of the excellent care they provide. And I love Ms.Lori she always their for me when I need something and she always answer my calls when I need to ask questions this agency is 10/10 for me I highly recommend ❤️Posted on Google Susy Barneond-KhaliliTrustindex verifies that the original source of the review is Google. They have been a God sent for me and my home health agency. Before them I was drowning in debt, insurances were not paying on time, after them, life is AWESOME!!Posted on Google Fidele NsengimanaTrustindex verifies that the original source of the review is Google. You are doing well, and keep it up so farPosted on Google Endaline OdoemeneTrustindex verifies that the original source of the review is Google. When I first got my hospice license, I honestly had no idea how complex the billing and Medicare side would be. That’s when Right On Time Billing Services stepped in—and they literally took me from day one. They handled everything: Medicare follow-ups, EDI, DDE access, getting us fully ready to take patients, helping us choose and set up the EMR, eligibility checks, and then complete hospice billing. What truly sets them apart is that they didn’t just “do the work”—they consulted and guided me with deep, real-world knowledge of medical billing and hospice operations. What impressed me most was that during the startup phase, they did not charge anything for all the guidance, setup, and support. Their pricing is extremely affordable, fair, and transparent—especially considering the level of expertise they bring. We have now been working with Right On Time Billing Services for over 2 years, and they continue to do an amazing job. Because of their accuracy, follow-ups, and compliance, my hospice has grown steadily and confidently. If you are starting a hospice, home health, or healthcare practice, or looking for a reliable medical billing company, I can confidently say this team is worth trusting. They don’t just bill—they care about your growth and success. Highly recommended!
