CPT code 30905 – Posterior nasal hemorrhage control

Key takeaways

CPT code 30905 covers initial control of a posterior nasal hemorrhage with posterior nasal packs and/or cautery, any method.

ICD-10 R04.0 (epistaxis) is the primary diagnosis paired with 30905, and the procedure note must state the posterior location explicitly.

Bill 30906 for a subsequent posterior control on the same bleed, never a second 30905.

When anterior and posterior control happen in one session, report 30905 alone, because NCCI bundles 30901 and 30903 into it.

CPT code 30905: Official descriptor and clinical scope

CPT code 30905 is the code for the initial control of a posterior nasal hemorrhage. The American Medical Association descriptor reads Control nasal hemorrhage, posterior, with posterior nasal packs and/or cautery, any method; initial. The code covers physician control of active bleeding from a posterior nasal source. Posterior hemorrhage control may be achieved by:

• Insertion of a posterior nasal pack (ribbon gauze, inflatable balloon catheter such as a Foley or dedicated epistaxis balloon)
• Electrocautery or chemical cautery of a posterior bleeding point under endoscopic visualization
• Combination approaches (cautery followed by packing for tamponade)

The technique is bundled into the code value. You do not change codes based on whether a balloon catheter versus gauze pack was used. What determines 30905 versus any other epistaxis code is anatomy (posterior origin) and service sequence (initial, not subsequent).

What 30905 does NOT cover:

• Anterior nasal bleeding, regardless of how complex the control technique was (use 30901 or 30903)
• A second session of control for the same posterior bleed on the same or a later date (use 30906)
• Packing material as a separate charge, because it is not separately billable with 30905
• Epistaxis that resolved with simple direct pressure and no physician intervention coded as a procedure

CPT 30905 vs. 30901, 30903, and 30906: Choosing the right code

The 309xx family covers four distinct epistaxis scenarios. Choosing the wrong one is a common source of denials. This table uses the AAPC CPT code reference framework to map each clinical scenario to the correct code.

30905 vs. 30906 decision logic: Bill 30905 for the first time posterior control is performed for a given bleed. If the physician must return to control bleeding from the same episode (the pack re-saturates, or the bleed recurs), bill 30906. Do not re-bill 30905 on a second encounter for the same posterior hemorrhage. That re-bill is a frequent sequencing error in this code family, and the decision path below puts both questions in order.

The anterior codes turn on extent. The posterior codes turn on sequence.

ICD-10 R04.0 epistaxis: Correct diagnosis codes to pair with CPT 30905

ICD-10 R04.0, Epistaxis, is the primary diagnosis code paired with CPT code 30905 on the claim. R04.0 is a billable code and requires no additional character beyond the fourth digit. The diagnosis alone does not establish medical necessity for the posterior approach. The documentation must support it.

Secondary diagnoses are not mandatory. They do strengthen the medical necessity argument when a payer asks why simpler anterior management was not enough. A claim for a hypertensive patient on warfarin who bled from a posterior source tells a clinically coherent story. R04.0 alone on a 30905 claim is technically correct but provides less context.

Medicare reimbursement rate and RVUs for CPT code 30905

Medicare pays CPT code 30905 under the CMS Medicare Physician Fee Schedule (MPFS). Rates differ by place of service and are adjusted by the Geographic Practice Cost Index (GPCI) for each Medicare Administrative Contractor (MAC) locality. The national figures below use the CY2026 relative values and the non-qualifying conversion factor of $33.4009. Qualifying APM participants are paid at $33.5675 instead.

The non-facility rate applies when the procedure is performed in the physician’s office. The facility rate applies in a hospital outpatient department or emergency department, where the facility is paid separately for its overhead. Nearly the whole difference sits in practice expense, at 9.53 RVUs in the office against 0.66 in a facility.

The RVUs come from the CMS PFS relative value file, and the MPFS look-up tool gives locality-adjusted rates. Commercial contracts vary. Many use the MPFS as a base multiplier, so the facility and non-facility split often carries over to commercial claims.

Documentation requirements to support a CPT code 30905 claim

A clean 30905 claim rests on a procedure note that documents six specific elements. An E/M note that only says the epistaxis was managed is not sufficient.

1. Anatomical location: State “posterior nasal hemorrhage” explicitly. Generic “epistaxis” is insufficient for 30905 versus 30901/30903.
2. Technique: Identify the specific method used (e.g., posterior nasal pack with Rapid Rhino balloon, electrocautery under nasal endoscopy, gauze pack with Foley catheter tamponade).
3. Laterality: Specify right, left, or bilateral. 30905 already covers either or both sides, so laterality is clinical documentation rather than a modifier trigger.
4. Pack duration (if applicable): If a pack is placed and left in situ, note the intended duration and instructions for follow-up removal.
5. Performing physician: Identify the physician who performed the procedure. This matters when a teaching physician was present in a hospital setting.
6. Medical necessity justification: Briefly state why anterior management was insufficient or inappropriate. Typical wording includes “bleed source not visible anteriorly,” “failed anterior packing,” or “posterior origin confirmed on nasal endoscopy.”

When 30905 is billed from an emergency department, the same documentation requirements apply. The place of service shifts the reimbursement rate; it does not change what the operative or procedure note must contain.

Modifier guidance for CPT code 30905

Two modifiers come up regularly on 30905 claims, and modifier 50 is not one of them. The code already describes posterior control on either or both sides, so modifier 50 is never appended. A wrong or missing modifier is a denial trigger worth catching in your claims management workflow before submission.

Same-day billing: CPT code 30905 with septoplasty or other nasal surgery

Billing CPT code 30905 on the same day as septoplasty code 30520 is a contested scenario in ENT coding. The core issue is NCCI (National Correct Coding Initiative) bundling. CMS maintains NCCI edit tables that identify procedure pairs where one code is typically included in another.

Check the current NCCI PTP table for the 30905 and 30520 pair before billing. Where an edit is active, payers bundle the epistaxis control into the surgical package unless a modifier applies. Inside the epistaxis family, NCCI bundles 30901 and 30903 into 30905, and 30906 is a Column 2 code to 30905.

When 30905 is included in the surgical package: A patient may bleed during or right after a septoplasty. The surgeon then controls it in the same operative session. That management is typically part of the global surgical package for 30520, and it is not separately billable.

When 30905 may be separately billable: A posterior hemorrhage can be a postoperative complication that needs a separate return to the procedure room. The bleed can also come from a site unrelated to the surgical field. In either case, modifier 59, or the more specific XS for a separate structure, may allow separate billing.

Document clearly that the bleeding source is distinct from the operative field and that a separate procedure was required. CMS updates the NCCI edit pairs quarterly, so verify the pair in the current table before billing. A practice’s denial management workflow should include a pre-claim NCCI check for any same-day surgical pair.

Common denial reasons for CPT code 30905 and how to fix them

30905 denials tend to trace back to six root causes. Each is preventable with the right documentation protocol and a pre-submission eligibility and edit check. Reading common denial codes alongside payer EOBs speeds up the appeals process.

• Missing posterior location documentation: The operative note says “epistaxis” without specifying posterior origin. Resolution: Template procedure notes to include “posterior nasal hemorrhage” as a required field. Appeals succeed with an addendum from the treating physician.
• Code bundled with surgical procedure: 30905 can bundle with same-day surgical codes under NCCI. Resolution: Check the NCCI edit table before billing. Add modifier 59 or XS only when the services were separate. Submit with supporting documentation on appeal.
• Wrong code selected: 30901 billed when documentation supports 30905, or 30905 re-billed when 30906 was correct for a subsequent service. Resolution: Audit procedure notes against the code family comparison table. Build coding decision logic into the billing workflow.
• Missing prior authorization: Some commercial and Medicare Advantage plans require authorization for 30905, particularly in an elective setting. Resolution: Check PA requirements for each payer at scheduling. Many payers treat emergency encounters differently, so document the emergent nature of the visit.
• Incorrect place of service code: Billing non-facility rates with a facility POS code, or vice versa. Resolution: Confirm the POS code matches where the procedure was physically performed. Office is POS 11, and an emergency department is POS 23.
• Diagnosis does not support medical necessity: R04.0 alone with no supporting note may not satisfy payer LCD requirements in some jurisdictions. Resolution: Include secondary diagnoses where clinically accurate and add a brief medical necessity statement to the note.

Prior authorization and payer-specific requirements

Prior authorization requirements for CPT code 30905 vary by payer, plan type, and care setting. Traditional Medicare does not generally require prior authorization for this code. Confirm the rule payer by payer, and document an emergent or urgent encounter as such, since many commercial payers handle those differently.

Medicare Advantage plans are not bound by traditional Medicare PA rules and many do require authorization. Commercial PPO and HMO plans vary widely. ENT practices billing 30905 to commercial payers should maintain a payer-specific PA matrix updated at least annually. For practices using the clean claim submission process, confirming authorization status before the claim goes out is a standard pre-transmission gate.

What most PA requests for 30905 require:

• Clinical notes documenting the nature, duration, and severity of the epistaxis
• Evidence that conservative measures (direct pressure, vasoconstrictor-soaked packing, topical hemostatic agents) were attempted and failed
• Physician specialty credentials confirming ENT or appropriate surgical competence
• Place of service and expected procedure date

How Pabau supports ENT billing for CPT code 30905

Billing 30905 well starts with a procedure note that names the posterior site and a coder who checks NCCI edits before submission. Today many ENT practices then re-key that claim into a separate clearinghouse portal. Pabau connects to the Claim.MD clearinghouse instead.

Your team submits CMS-1500/837P claims, checks eligibility and receives 835 ERAs through Claim.MD without leaving Pabau. The remittance lands on the same patient record as the procedure note. A denial can then be read beside the documentation behind it.

Every plan includes the core features, and add-ons enhance the experience. In a practice with a high volume of ENT procedure claims, billing staff spend less time moving data between systems. That time goes to the claims that need judgment.

Conclusion

CPT code 30905 rewards precision in the procedure note. The phrase “posterior nasal hemorrhage” is what separates a payable 30905 from a downcode to 30901. Write the site and the technique into every note, and pick the code by site first and sequence second. Check NCCI edits before any same-day surgical claim.

The trade-off is a few extra lines of documentation per encounter, which cost far less than an appeal. Pabau lets ENT practices submit those claims, check eligibility and track remittances through Claim.MD in one place. Book a demo to see how that workflow handles 30905 and the wider ENT code set.
