Top 10 Infectious Disease Billing Companies in Washington

A single infectious disease patient can generate an office visit, a hospital consult, a send-out culture, a prior authorization for a costly antimicrobial and a telehealth follow-up, all in one month. Each piece needs documentation that supports the E/M level, diagnosis codes specific enough to name the infection, and a payer that agrees the treatment was necessary. When any link slips, claims stall, denials pile up and accounts receivable ages. Specialty-aware billing matters here because the work is long-running, documentation-heavy and policy-driven. This guide compares 10 billing and revenue cycle management (RCM) companies that serve Washington providers, either locally or remotely, and explains what to ask before you outsource.

Sirius Solutions Global: Medical Billing and RCM Support for Infectious Disease Practices
Sirius Solutions Global supports healthcare organizations with technology-assisted, human-verified medical billing and revenue cycle management. Software flags routine problems; trained staff review the rest. Our services include advanced eligibility verification, medical coding, claims management, denial management, prior authorization, credentialing and re-credentialing, A/R follow-up, medical billing audits, revenue leakage assessments and virtual assistant support.
For infectious disease practices, that means checking coverage and authorizations before visits, reviewing codes against documentation, scrubbing claims before submission, sorting denials by root cause and working aged A/R on a schedule. We are a multi-specialty RCM company. We don’t claim infectious disease-specific clients, certifications or Washington offices, so ask how your coding and payer requirements would be handled.

Why Infectious Disease Medical Billing Requires Specialty-Aware Expertise
Area | What to know |
E/M coding | Office and hospital visits are leveled by medical decision making or time. Notes must show the work, such as drug therapy that needs monitoring for toxicity. |
Diagnosis coding | ICD-10-CM infection codes often depend on organism, site and resistance. Vague notes lead to vague codes and denials. |
Labs and diagnostics | Send-out tests are billed by the performing lab. In-office testing needs the right CLIA certificate, and some waived tests need a modifier. |
Antimicrobials and infusion | Where a practice provides infusion, administration codes need documented times and routes, and drugs need correct units. Many practices don’t offer this. |
Chronic management | Ongoing care, such as HIV or hepatitis C, adds recurring authorizations, monitoring labs and long visit histories. |
Telehealth | Payers differ on place of service, modifiers and audio-only rules. Confirm each payer’s policy. |
Denials | Eligibility gaps, missing authorization, thin documentation and coding mismatches are common causes. |

Where infectious disease revenue can slip.
2026 Medicare snapshot The 2026 Medicare conversion factor is $33.4009 for non-qualifying APM clinicians and $33.5675 for qualifying participants (summary). CMS proposed $32.8409 and $33.1693 for 2027 (AMA); confirm final figures. Medicare telehealth flexibilities run through Dec. 31, 2027 (summary). |
Where Infectious Disease Practices May Be Losing Revenue
Revenue leakage area | Common problem | Recommended RCM action |
Eligibility | Coverage errors | Advanced eligibility checks |
Coding | Incorrect or incomplete coding | Coding review |
Documentation | Missing supporting details | Documentation review |
Claims | Submission errors | Claim scrubbing |
Denials | Unresolved denied claims | Denial management |
A/R | Delayed follow-up | Structured A/R management |
Authorization | Missing required approvals | Prior authorization workflows |
Underpayments | Incorrect reimbursement | Payment and contract review |
Illustrative only; these steps don’t guarantee recovered revenue.

How to Choose the Right Infectious Disease Billing Company in Washington
Selection criteria | What to ask |
Specialty experience | Have you supported infectious disease practices? |
Medical coding | Who reviews coding accuracy? |
Claims management | How are claims checked before submission? |
Denial management | How are denial trends identified? |
A/R management | How often are outstanding claims followed up? |
Eligibility | How are coverage errors identified? |
Technology | Which billing and reporting systems are supported? |
Human support | Will experienced specialists manage the account? |
Compliance | How are HIPAA and billing compliance handled? |
Transparency | What reports and metrics are provided? |
The lowest fee shouldn’t be your only filter. A cheap contract that leaves denials unworked or coding unreviewed can cost more than it saves, so compare scope, reporting, contract terms and who actually handles your account.
What Washington Infectious Disease Practices Should Consider When Choosing a Billing Partner
• Federal (CMS): Medicare Part B in Washington is processed by Noridian (JF). CMS sets national coding and payment rules.
• State (Apple Health): The Health Care Authority runs Medicaid through ProviderOne. Many clients are in managed care plans with their own billing instructions.
• Commercial payers: Each sets its own policies. The Office of the Insurance Commissioner oversees state-regulated plans, not self-funded employer plans.
• Telehealth: Medicare, Apple Health and commercial rules differ. See HCA’s telemedicine billing guide.
• Credentialing: Enrollment is payer-by-payer, and delays hold claims.
• Privacy: HIPAA applies, and Washington’s Uniform Health Care Information Act (RCW 70.02) may add state rules. Sign a business associate agreement and confirm with counsel.
