Coverage Criteria for Balloon Ostial Dilation (BOD)
inv-01: Covered Indications and Preconditions
Covered when ALL of the following are met
From general criteria (3.1)
From general criteria (3.1)
From general criteria (3.1)
Medicaid eligibility/age requirement (Subsection 2.1 and EPSDT note)
Medical therapy requirements (1.1.5)
inv-02: Covered Indications
Covered when ALL of the following are met
From general criteria (3.1)
Specific criteria (3.2.1)
This policy does not address Functional Endoscopic Sinus Surgery (FESS). FESS is a separate endoscopic surgical procedure for removal of abnormal or obstructive sinus tissue, and coverage determinations for FESS are outside the scope of this BOD policy. Balloon Ostial Dilation (BOD) is discussed independently from FESS in this document.
Balloon Ostial Dilation (BOD) is not covered when performed for the following conditions: nasal polyps or tumors; Samter's Triad (aspirin sensitivity); severe sinusitis secondary to autoimmune or connective tissue disorders (for example, sarcoidosis or Wegener's granulomatosis); severe sinusitis secondary to ciliary dysfunction (for example, cystic fibrosis); contraindication to or inability to tolerate local or topical anesthetic; history of a failed balloon procedure in the sinus to be treated; sinusitis with extensive fungal disease; or significant neo-osteogenesis confirmed by CT.
When Balloon Ostial Dilation (BOD) is performed as an adjunct during Functional Endoscopic Sinus Surgery (FESS), the BOD component is considered integral to the primary FESS procedure and is not separately reimbursable.
BOD is not covered when the beneficiary does not meet the eligibility requirements in Section 2.0, does not meet the clinical criteria in Section 3.0, when the procedure duplicates another provider's service, or when the procedure is experimental, investigational, or part of a clinical trial.
Coding and Procedure Codes
Provider Requirements, Prior Authorization, and Documentation
Prior approval required when specified
Prior approval is required for Balloon Ostial Dilation (BOD). When prior approval is required, providers must submit the prior approval request through the DHHS Utilization Review Contractor and include all supporting documentation as described in Subsections 5.2.1 and 5.2.2. For beneficiaries under 21, EPSDT does not waive the prior approval requirement — providers must still obtain prior approval when applicable and document medical necessity per EPSDT guidance.
- Submit prior approval request to DHHS Utilization Review Contractor (see Subsection 5.2.1).
- Include all health records supporting that beneficiary meets specific criteria in Subsection 3.2 (see Subsection 5.2.1.b).
- Otolaryngologist must include signed letter of medical necessity, clinical history, sinus documentation, failed medical therapy documentation (see Subsection 1.1.5), and CT findings as specified in Subsection 5.2.2.
- EPSDT (beneficiaries <21) still requires prior approval when the procedure is subject to prior approval; include EPSDT rationale in documentation.
Eligibility verification required
Providers must verify Medicaid eligibility at the time of service for every beneficiary. Services provided when the beneficiary is not enrolled in NC Medicaid or eligibility cannot be verified at the time of service may be denied.
- Verify each beneficiary's NC Medicaid eligibility via NCTracks prior to rendering services.
- If beneficiary is not enrolled or eligibility is not verified at time of service, claim may be denied.
General denial triggers
Claims may be denied for several general reasons. Providers should confirm that beneficiaries meet Section 2.0 eligibility, meet Section 3.0 coverage criteria, avoid duplicate services, and ensure services are not experimental or investigational.
- Denial triggers include: beneficiary not meeting Section 2.0 eligibility, not meeting Section 3.0 criteria, duplication of another provider's procedure, or service classified as experimental/investigational/clinical trial.
- Failure to obtain required prior approval when mandated may also result in denial.
Coding specificity requirement
Report diagnosis and procedure codes to the highest level of specificity that supports medical necessity. Use the current ICD-10-CM and CPT/HCPCS editions in effect at the time of service.
- Report ICD-10-CM and PCS codes to the highest level of specificity that supports medical necessity.
- Use current CPT, HCPCS, and UB-04 specifications in effect at time of service.
Required documentation for prior approval
Submit the prior approval request plus all health records that demonstrate the beneficiary meets the policy-specific criteria. The Otolaryngologist must include specialty-specific documentation as listed below.
- Prior approval request and all supporting health records showing criteria in Subsection 3.2 are met (Subsection 5.2.1).
- Signed letter of medical necessity by the attending physician and summary of clinical history (Subsection 5.2.2.a).
- Documentation of which sinus is involved (Subsection 5.2.2.b).
- Documentation of attempted and failed medical therapy (refer to Subsection 1.1.5) for persistent chronic or recurrent acute rhinosinusitis (Subsection 5.2.2.c).
- CT scan findings documentation showing one or more specified findings (mucosal thickening >2 mm, complete opacification, bone remodeling/thickening, or obstruction of the ostiomeatal complex) as noted in Subsection 5.2.2.d.
Procedure coding and special report
Use the most specific CPT/HCPCS code that accurately and completely describes the procedure. If no specific code exists, report the appropriate unlisted procedure code and submit the required special report per CPT/HCPCS instructions.
Reference documentation
Providers shall comply with NCTracks guides, Medicaid bulletins, fee schedules, and NC Medicaid clinical coverage policies for coverage, reimbursement, prior authorization processes, and billing procedures.
- Consult NCTracks Provider Claims and Billing Assistance Guide and Medicaid bulletins for operational details and web portal processes.
- Follow fee schedules and clinical coverage policies for reimbursement and coverage determinations.
Definitions and Clinical Terms
Background and Clinical Context
Balloon Ostial Dilation (BOD), also called balloon dilation sinuplasty or balloon catheter sinusotomy, is a procedure that places and inflates a balloon in the sinus ostium to dilate the opening. BOD may be performed as a stand-alone procedure for chronic rhinosinusitis or as an adjunct to Functional Endoscopic Sinus Surgery. Approaches include transnasal (through the nostrils, often with fluoroscopic guidance) and transantral (via a small entry point under the lip). Procedures are typically performed under general anesthesia, though local anesthesia may be used in some cases. Potential advantages include minimal mucosal damage, minimal intraoperative bleeding, and reduced discomfort compared with more invasive FESS.
Policy Revision History
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
