CPT 92552: Complete Guide to Pure Tone Audiometry Billing and Coding
Pure tone audiometry is one of the most common hearing tests, and one of the easiest to code wrong. A claim can fail because the test was bone conduction as well, because an order was missing, or because a broader audiometry code made 92552 redundant. At MedCloudMD, our billing specialists see these small mismatches turn into delays and rework. This resource explains how CPT 92552 is reported and what to check before the claim leaves your office.
CPT 92552 Quick Reference
Field | Detail |
CPT | 92552 |
Service | Pure tone audiometry |
Primary focus | Accurate coding, documentation, medical necessity, and billing |
Audience | Providers, audiologists, coders, billers, and practice managers |
What Is CPT 92552?
CPT 92552 reports pure tone audiometry (threshold), air conduction only. The clinician presents tones at different frequencies through headphones or inserts and records the softest level the patient responds to. From a billing view, the code describes a diagnostic threshold test, and the audiogram is the proof it was done.
When Is CPT 92552 Reported?
It may be reported when air conduction threshold testing was actually performed and documented. If bone conduction was also tested, a different code describes air and bone testing. If a full battery was done, a comprehensive audiometry code may apply instead. The code must follow the service, not the other way around. A screening test is not the same as a threshold test.
Code | Descriptor (verify current CPT) | Billing Consideration |
92551 | Screening test, pure tone, air only | Screening, not threshold testing |
92552 | Pure tone audiometry (threshold); air only | Air conduction threshold |
92553 | Pure tone audiometry (threshold); air and bone | Use when both are tested |
92555, 92556 | Speech audiometry threshold; with speech recognition | Speech testing is separate |
92557 | Comprehensive audiometry threshold evaluation and speech recognition | Bundles pure tone testing; check NCCI for same day pairs |
CPT 92552 Documentation Requirements
Good documentation tells a reviewer who was tested, why, what was done, and what was found. Many items below reflect good practice rather than a universal rule, so separate them from payer requirements.
Good practice (broadly applicable):
• Patient information and date of service.
• Reason for testing and relevant clinical indication.
• The test performed, and the results or audiogram.
• Provider or qualified professional documentation.
Payer specific (verify each payer):
• A physician or practitioner order. Medicare generally expects one for diagnostic audiology.
• Diagnosis, frequency, and coverage rules.
• Prior authorization, when a plan requires it.
CPT 92552 Billing and Coding Considerations
• Code selection: choose the code that matches the test documented, not the one that pays more.
• Documentation to code match: the audiogram and note must support what is billed.
• Diagnosis coding: link to the documented clinical indication.
• Modifiers: use only when circumstances and payer rules call for them. No modifier is universally required.
• Edits: review current NCCI and payer edits, especially against 92553 and 92557 on the same date.
• Eligibility and benefits: verify coverage, hearing benefits, and limits before the visit.
Billing tip: If the record shows bone conduction was tested, check whether 92552 still describes the service before the claim goes out. |
Common CPT 92552 Billing Errors
Common Error | Why It Matters | Better Practice |
Billing 92552 when bone conduction was done | The claim may understate or misstate the service | Match the code to air only or air and bone |
Billing 92552 with 92557 | The comprehensive code already includes pure tone testing and edits may deny a line | Check NCCI before same day pairs |
Missing order | Some payers require one for diagnostic testing | Confirm order rules at scheduling |
Billing a screening as a threshold test | Screening is a different service | Code only the test performed |
Weak diagnosis linkage | Claim may not show why the test was needed | Match the diagnosis to the documented indication |
No audiogram in the chart | Raises audit and medical necessity concerns | Save results with every test |
Ignoring payer policy | Requirements vary by payer | Verify current payer guidance |
Are CPT 92552 Claims Creating Billing Challenges?
Let MedCloudMD’s billing specialists help your practice identify billing gaps, improve claim workflows, and manage the revenue cycle.
CPT 92552 and Medical Necessity
Medical necessity means the record shows why the test was reasonable for this patient. A diagnosis code on the claim is not enough on its own. The clinical note should explain the symptoms or concern that led to testing, and the diagnosis should match it. No diagnosis automatically establishes medical necessity for every payer.
Medicare and Insurance Considerations
Medicare and commercial payers do not treat audiometry the same way. Medicare may cover medically necessary diagnostic audiology testing, while hearing exams tied to fitting hearing aids are generally treated differently. Commercial plans vary in coverage, authorization, and frequency. Before billing, verify current coverage, documentation, frequency, diagnosis, and payment rules in the payer’s fee schedule, medical policy, LCD or NCD where applicable, and provider manual.
CPT 92552 Denials: What Should Billing Teams Check?
☐ Was the correct CPT code selected? | ☐ Does the documentation support the billed service? |
☐ Is the diagnosis appropriately linked? | ☐ Was medical necessity supported? |
☐ Was the patient’s coverage verified? | ☐ Were payer specific requirements reviewed? |
☐ Were claim edits or coding conflicts checked? | ☐ Does the record support the date and service billed? |
CPT 92552 Reimbursement and Revenue Cycle Impact
Payment varies with the payer, geographic location, contract, patient coverage, place of service, allowed amount, deductible and coinsurance, payer policy, and claim accuracy. We do not quote a figure, because any single number would mislead. Preventable errors create denials, resubmissions, and extra staff time, which cost a practice even when the claim is eventually paid.
CPT 92552 Billing Workflow
Verify | Document | Code | Review | Submit | Track | Resolve |
Step | What Happens |
Verify | Confirm eligibility, benefits, and order or authorization requirements. |
Document | Record indication, test performed, and results. |
Code | Select the code and diagnosis that match the record. |
Review | Check edits, payer rules, and claim details. |
Submit | Send a clean claim promptly. |
Track | Monitor status and follow up on aging claims. |
Resolve | Work denials by reason and fix the root cause. |
Why Accurate Billing Matters
Accurate documentation and correct coding improve claim quality, reduce denials, support timely reimbursement, protect compliance, and give practice leaders clearer revenue cycle visibility.

CPT 92552 FAQ
What is CPT 92552?
CPT 92552 is the code for pure tone audiometry (threshold), air conduction only. It reports a hearing threshold test that measures responses to tones through air conduction.
What does CPT 92552 include?
Air conduction threshold testing. Bone conduction testing is reported separately under a different code, and comprehensive audiometry has its own code. Verify current CPT descriptors.
What documentation is important for CPT 92552?
Typically the clinical indication, the test performed, the results or audiogram, the date, and the provider’s documentation. Payers may add their own requirements.
Can CPT 92552 be billed to Medicare?
Medicare may cover medically necessary diagnostic audiology testing, generally when ordered by a physician or qualified practitioner. Routine hearing exams for hearing aid fitting are handled differently. Verify current Medicare and MAC policy.
Why might a CPT 92552 claim be denied?
Common reasons include missing medical necessity, no order where one is required, a coding edit conflict, and coverage or frequency limits.
How does medical necessity affect CPT 92552 billing?
The record must show why the test was needed. A diagnosis code on the claim alone does not establish medical necessity.
How can a medical billing company help with audiometry billing?
A billing team can review coding and documentation, verify eligibility, check edits, work denials, and follow up on A/R so errors are caught early.
