Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Investigational / Not covered as standard of care

Covered when ALL of the following are met:

Investigational technologies: Rhinomanometry, acoustic rhinometry and optical rhinometry are considered investigational; the evidence does not permit conclusions about their effect on net health outcome and no studies have demonstrated clinical utility via prospective comparison of outcomes.

All device types and commercial names are considered investigational regardless of FDA status.

All rhinomanometers and acoustic rhinometers used to measure nasal patency are considered investigational regardless of commercial name, manufacturer, or FDA approval status.

Outpatient rhinomanometry, acoustic rhinometry, and optical rhinometry are not covered for Commercial Managed Care (HMO and POS), Commercial PPO and Indemnity, Medicare HMO BlueSM, and Medicare PPO BlueSM members.

The rationale for noncoverage is that the scientific evidence does not permit conclusions about the effect of rhinomanometry, acoustic rhinometry, or optical rhinometry on net health outcome. No studies have prospectively compared patient outcomes with and without these tests, and clinical utility has not been demonstrated.

Provider Actions and Requirements

Prior Authorization

Prior Authorization Required for Inpatient Procedures

Precertification / preauthorization is required for all inpatient procedures described in this policy. Providers must obtain approval prior to inpatient admission to avoid potential denial of payment or reduced reimbursement.

Applies to all products when the procedure is performed inpatient
Contact Blue Cross Blue Shield - Massachusetts prior authorization department for submission requirements and timelines

Note

Providers performing services covered by this policy should confirm prior authorization requirements and follow payer submission procedures. Verify member eligibility, benefit coverage, and obtain any required authorizations before scheduling services.

Verify member eligibility and benefit coverage before service
Confirm authorization reference number and include on claims

Documentation Required

Coding and Documentation

Providers must use current industry-standard procedure (CPT/HCPCS/revenue) and diagnosis (ICD-10) codes, including appropriate modifiers, when reporting services. Accurate coding and documentation support medical necessity determinations and claims processing.

Report services using up-to-date CPT, HCPCS, Revenue, and ICD-10 codes
Include appropriate modifiers and supporting documentation with authorization and claims

Denial Risk

Outpatient Noncoverage

Outpatient rhinomanometry, acoustic rhinometry, and optical rhinometry are not covered when performed in the outpatient setting for the products listed below.

Commercial Managed Care (HMO and POS) — Outpatient: Not a covered service
Commercial PPO and Indemnity — Outpatient: Not a covered service
Medicare HMO Bluesm — Outpatient: Not a covered service
Medicare PPO Bluesm — Outpatient: Not a covered service

Denial Risk

Inpatient Prior Authorization Requirement and Payment Risk

Failure to obtain required precertification/preauthorization for inpatient procedures may result in denial of payment or reduced reimbursement. Providers are responsible for confirming authorization prior to admission.

Precertification must be obtained before inpatient admission for services in this policy
Claims submitted without required prior authorization may be denied or subject to payment reduction

Background

Rhinomanometry, acoustic rhinometry, and optical rhinometry are objective techniques intended to assess nasal patency and nasal airway geometry. Rhinomanometry measures air pressure and airflow during respiration to calculate nasal airway resistance. Acoustic rhinometry assesses the geometry of the nasal cavity and nasopharynx by analyzing sound waves reflected from the nasal cavities. Optical rhinometry uses an emitter and detector placed on opposite sides of the nose to detect relative changes in nasal congestion by measuring transmitted red/near‑infrared light absorption by hemoglobin.

Definitions

Rhinomanometry — definition and brief description

DefinitionRhinomanometry is a test of nasal function that measures air pressure and the rate of airflow in the nasal airway during respiration to calculate nasal airway resistance.

PurposeProvides an objective quantification of nasal airway patency to assist evaluation of nasal obstruction.

Proposed clinical applicationsUsed in evaluation for allergy testing, obstructive sleep apnea assessment, and preoperative assessment prior to nasal surgery.

LimitationsPerception of nasal obstruction is subjective and may not correlate with clinical examination or objective measurements.

Acoustic rhinometry — definition and brief description

DefinitionAcoustic rhinometry is a technique for assessment of the geometry of the nasal cavity and nasopharynx by analysis of sound waves reflected from the nasal cavities.

PurposeEvaluates nasal obstruction by measuring cross-sectional area and volume changes within the nasal passages.

Technique basisRelies on analysis of reflected sound waves to infer internal nasal cavity geometry.

Proposed clinical applicationsMay be used for allergy assessment, obstructive sleep apnea evaluation, and preoperative planning for nasal surgery.

Optical rhinometry — definition and brief description

DefinitionOptical rhinometry uses an emitter and a detector placed on opposite sides of the nose to detect relative changes in nasal congestion by measuring changes in transmitted red/near-infrared light absorbed by hemoglobin.

PurposeDetects endonasal swelling-associated increases in local blood volume as an indirect measure of nasal congestion.

Technique basisBased on absorption of red/near-infrared light by hemoglobin; changes in transmitted light signal reflect changes in nasal congestion.

Proposed clinical applicationsProposed uses include assessment for allergy, evaluation related to obstructive sleep apnea, and preoperative assessment before nasal surgery.
