Advantages of Our Innovative Pathology Medical Billing Services
HBS’s pathology billing and coding services requires specialized expertise in dual coding systems, anatomic pathology (88000–88399) and clinical pathology (80047–85999). Our certified coders navigate surgical pathology levels (88300–88309), immunohistochemistry (88342–88346), molecular diagnostics (81000–81479), and cytopathology (88104–88199), ensuring accurate complexity-based coding.
Proper ICD-10 coding establishes medical necessity for every test. We expertly apply critical modifiers: -26 (professional component), -TC (technical component), -90 (reference lab), and -91 (repeat testing). Missing or incorrect modifiers cause the majority of pathology claim denials, our expertise protects your revenue from these preventable errors.
MIPS Specialists
MIPS determines Medicare payments through four performance categories: Quality (30%), Cost, Improvement Activities (15% large practices, 50% small), and Promoting Interoperability (25%). Pathology labs must report six quality measures and complete IA attestations to avoid penalties and earn maximum incentives.
Our MIPS specialists handle pathology-specific quality measures including Barrett’s esophagus documentation, prostatectomy report completeness (pT, pN, Gleason score, margins), and MMR testing recommendations. We manage data collection, measure selection, and timely CMS submission, protecting your Medicare reimbursement from payment adjustments.
CLIA Compliance and RCM Management
Your lab’s revenue cycle depends on CLIA compliance, accurate documentation, and optimized front-office (insurance verification, authorization) and back-office (coding, claims, payment posting) procedures. Medical credentialing and CLIA certification numbers on claims are essential; missing CLIA numbers trigger CO-16 denials immediately.
Our expert denial management addresses CO-4 (missing modifier), CO-16 (lacks CLIA/information), CO-97 (bundling issues), and CO-167 (medical necessity) codes. With narrow provider networks and stricter payer policies, you must verify eligibility before services, maintain HIPAA-compliant documentation, capture charges from your LIS accurately, and conduct systematic A/R follow-up.
Unique Billing Challenges Pathology Practices Face
Pathology billing services are the most complex in healthcare. Labs struggle with dual coding requirements, anatomic pathology (88000-88399) and clinical pathology (80047-85999), while managing technical versus professional component splits. Single cases involve multiple specimens requiring different CPT complexity levels (88300-88309), each needing accurate ICD-10 codes to establish medical necessity.
Common challenges include missing modifiers (-26, -TC) causing immediate denials, CLIA certification number omissions triggering CO-16 rejections, bundling errors resulting in CO-97 denials, and medical necessity failures (CO-167). Molecular diagnostics demand prior authorization, narrow provider networks create out-of-network issues, and keeping current with annual CPT updates, payer LCDs, MIPS reporting, and HIPAA compliance overwhelms internal teams. This is precisely why many practices choose to outsource pathology billing services to a dedicated specialist rather than manage it in-house.
Precision, Efficiency, and Security in Every Step of Billing for Pathology Practices
With the assistance of our outsourced pathology billing services, we process a claim through each phase, from receipt of the specimen to final payment, while complying with pathology billing rules.
1
Patient Registration &Charge Capture
The Laboratory Information System(LIS) is integrated to receive and capture accurate order and demographic data when the specimen is received
2
Eligibility & Insurance Verification
Real-time patient eligibility verification confirms that the patient has an active insurance policy and coverage for pathology medical billing services.
3
CPT & ICD-10 Coding
CCPC and CCS coders will assign the correct CPT/ICD-10 code(s) and any required modifier(s) for all pathology medical billing services provided.
4
Claim Scrubbing & Submission
Claims are scrubbed at multiple levels for NCCI edits, Clinical Laboratory Improvement Amendment (CLIA) numbers, accurate modifiers, and payer-specific claim submission requirements before submission.
5
Payment Posting & EOB Reconciliation
Payments are received electronically via ERA and EFT and are reconciled with the claim payment(s); underpayments are flagged for follow-up.
6
Denial Management & A/R Follow-up
All denials associated with CO-4, CO-16, CO-97, and CO-167 are managed, including targeted appeals and root cause analysis/corrections.

Frequently Asked Questions About Pathology Billing Services
Pathology billing services are responsible for accurate coding and submission of claims, as well as managing claim submission for anatomic and clinical laboratory tests in order to ensure proper reimbursement and compliance with payer requirements.
There are several reasons that make billing for pathology services complex, including the use of both a CPT coding system that has multiple ranges, the ability to code for two different components (professional and technical), the use of modifiers, compliance with CLIA regulations, and payers having separate rules regarding documentation requirements.
Modifiers such as +26, +TC, +90, and +91 are essential to correctly billing for pathology services because improper use or improperly placed modifiers are one of the most significant factors in having claims denied and overall slow payment on claims.
Common denial reasons experienced by pathology services include failure to provide CLIA numbers, not using accurate codes, lack of medical necessity, use of bundled codes, and incorrect coding using CPT codes or ICD-10 codes.
A complete and accurate CLIA number must be on all claims for CLIA laboratory testing services. Claims that do not include a valid CLIA number will automatically be denied.
Pathology billing services will enhance a practice’s revenue cycle by reducing the number of denied claims, providing accurate coding, expediting the collections process after submission of a claim, increasing the percentage of clean claims submitted, and ensuring compliance with the appropriate payer regulations.
HBS offers complete billing support for pathology practices related to CPT/ICD-10 coding, denial management, CLIA compliance, A/R follow-up, and the optimization of revenue cycles, resulting in maximum reimbursement for pathology practices.
Our primary focus is to help practices improve profitability, maintain long-term sustainability, and enhance patient-centered care.
