Crystal's MCW Coder Hub👩🏾⚕️ CPT Code 30901 — Control of Anterior Nasal Hemorrhage, Simple
Official Full Descriptor
Control nasal hemorrhage, anterior, simple (limited cautery and/or packing) any method
This code represents the treatment of an anterior nosebleed using limited cautery and/or packing by any method available. The defining feature is the qualifier “simple” — meaning the hemorrhage was easily controlled with limited intervention applied to a restricted area of the anterior nasal cavity. If the bleeding is difficult to control, involves multiple sites, or requires extensive treatment, CPT 30903 applies instead. The phrase “any method” means the specific technique used (silver nitrate, electrocautery, absorbable packing, non-absorbable packing, topical hemostatic agents) does not change the code — the severity and extent of the intervention determines simple vs. complex.

Full Epistaxis Control Code Family — Complete Reference
Understanding the entire epistaxis code family is essential, as selecting the wrong code is one of the most common ENT coding errors. The family is small — only four codes — but each has specific criteria and NCCI bundling implications.
Anterior Epistaxis Control
| CPT | Full Descriptor | Key Distinction | wRVU (approx.) |
|---|---|---|---|
| 30901 | Control nasal hemorrhage, anterior, simple (limited cautery and/or packing) any method | Easily controlled; limited area; minimal intervention | ~1.31 |
| 30903 | Control nasal hemorrhage, anterior, complex (extensive cautery and/or packing) any method | Difficult to control; multiple sites; aggressive packing; prolonged effort | ~2.42 |
Posterior Epistaxis Control
| CPT | Full Descriptor | Key Distinction | wRVU (approx.) |
|---|---|---|---|
| 30905 | Control nasal hemorrhage, posterior, with posterior nasal packs and/or cautery, any method; initial | First treatment for posterior bleed (this encounter); bilateral by nature | ~3.01 |
| 30906 | Control nasal hemorrhage, posterior, with posterior nasal packs and/or cautery, any method; subsequent | Repeat posterior treatment when initial treatment failed or bleed recurred | ~3.88 |
Endoscopic Hemorrhage Control (Distinct from Above)
| CPT | Description | Key Distinction | wRVU (approx.) |
|---|---|---|---|
| 31238 | Nasal/sinus endoscopy, surgical; with control of nasal hemorrhage | Use when the endoscope is the primary tool for identification AND control, not merely for visualization | ~4.84 |
Critical Note on 31238 vs. 30901-30906: If a physician uses a nasal endoscope solely to locate the bleeding site and then proceeds to control it with traditional cautery/packing, report 30901-30906 (whichever applies) — not 31238. If the endoscope is the active instrument used to control the hemorrhage (e.g., endoscopic-guided cautery directly through the scope), report 31238. These distinctions are detailed further in the Excludes section below.
Procedure Description — What CPT 30901 Represents
Clinical Definition
CPT 30901 captures the treatment of an anterior epistaxis (nosebleed arising from the front of the nasal cavity, most commonly the anterior nasal septum at Kiesselbach’s plexus / Little’s area) that is successfully controlled with a limited, straightforward intervention. The “simple” designation reflects clinical ease of control — the bleed was isolated, accessible, and responded promptly to treatment without requiring escalating or extensive measures.
Anatomy — Anterior vs. Posterior Epistaxis
Understanding the anatomical distinction between anterior and posterior bleeds is the foundation of epistaxis coding:
Anterior Epistaxis (coded 30901 or 30903):
- Originates in the anterior nasal cavity, most commonly at Kiesselbach’s plexus (Little’s area) on the anterior nasal septum — a richly vascularized confluence of the anterior ethmoidal artery, the sphenopalatine artery branches, the greater palatine artery, and the superior labial artery
- Represents approximately 90-95% of all nosebleeds
- Typically visible on anterior rhinoscopy or nasal speculum examination
- Usually controllable in the office, ED, or at bedside without general anesthesia
- Often associated with: nasal trauma, digital manipulation (nose picking), dry air, topical steroid or antihistamine spray use, septal deviation, coagulopathy
Posterior Epistaxis (coded 30905 or 30906):
- Originates from the posterior nasal cavity, nasopharynx, or from branches of the sphenopalatine artery or posterior ethmoidal artery deep in the nasal vault
- Represents approximately 5-10% of epistaxis cases but is disproportionately responsible for serious, life-threatening bleeds
- Blood drains posteriorly into the pharynx; patient may swallow blood or present with hematemesis
- Typically requires posterior nasal packing, balloon tamponade, or surgical/interventional management
- More common in older patients with hypertension, atherosclerosis, or anticoagulation
- Higher rates of inpatient admission
Kiesselbach’s Plexus — Why 30901 Is So Common
The anterior septal mucosa at Little’s area is supplied by four arterial systems forming a rich anastomotic network. This area is thin, superficial, and highly vulnerable to trauma, drying, and inflammation. The overwhelming majority of anterior nosebleeds — the most common type — arise here and are readily visualized and treated with simple silver nitrate cautery or brief anterior packing. This is why 30901 is one of the most frequently reported otolaryngology procedure codes across all practice settings.
Methods Included Under “Any Method” in 30901
The CPT descriptor specifies “any method,” meaning all of the following techniques fall under 30901 (or 30903) when used for anterior epistaxis control. The method used does not change the code; only the extent and difficulty of treatment (simple vs. complex) determines code selection:
- Chemical cautery — silver nitrate sticks applied to the bleeding vessel or mucosa; the most common office-based technique for simple anterior bleeds; chemical reaction causes protein denaturation and hemostasis
- Electrocautery — monopolar or bipolar electrocautery to coagulate the bleeding vessel; used when silver nitrate fails or when the vessel is larger
- Anterior nasal packing — non-absorbable — petroleum gauze (e.g., Vaseline gauze), merocel sponge tampons, or ribbon gauze layered into the anterior nasal cavity to provide tamponade pressure
- Anterior nasal packing — absorbable — oxidized cellulose (Surgicel), gelatin sponge (Gelfoam), or thrombin-soaked absorbable materials; these dissolve over days and do not require removal
- Nasal balloon tamponade devices — Rapid Rhino, Rhinorocket, Epistat — inflatable devices that provide circumferential tamponade; while these are more often associated with 30903, a small/limited balloon may qualify as 30901 depending on documentation of clinical ease
- Topical vasoconstrictors/hemostatics — oxymetazoline (Afrin), phenylephrine, TXA (tranexamic acid) — used as adjuncts; however, if hemostasis is achieved with topical agents alone (no packing left in place, no cautery), the appropriate code is an E&M, not 30901; see Coding Rule section
- Direct pressure — finger compression; if hemostasis is achieved with pressure alone and no packing or cautery is performed, 30901 is not reportable; document an E&M instead
- Floseal / Surgiflo — topical hemostatic matrix agents (thrombin + gelatin matrix); considered under “any method”; may support 30901 or 30903 depending on extent of application
Simple vs. Complex — The Key 30901 vs. 30903 Decision
The CPT distinction between simple (30901) and complex (30903) is intentionally not rigidly defined in the code descriptors. The AMA uses the terms “limited” (30901) and “extensive” (30903). The clinical judgment of the treating provider, documented in the chart note, governs this distinction. General guidance:
| Feature | 30901 — Simple | 30903 — Complex |
|---|---|---|
| Bleeding site | Single, easily identified | Multiple sites; difficult to identify |
| Location | Accessible anterior septum | Deeper anterior nasal cavity; lateral wall |
| Intervention extent | One or two silver nitrate applications; minimal packing | Prolonged cautery; multiple applications; bilateral cautery; extensive layered packing |
| Time/difficulty | Brief; readily controlled | Prolonged effort; escalation of treatment required |
| Clinical course | Bleed stopped promptly | Bleed difficult to control; multiple attempts needed |
| Packing type | Limited cotton pledget, small absorbable pack, brief silver nitrate | Full anterior pack, nasal balloon, merocel tampon, multiple-layer gauze |
Note
There is no absolute objective threshold separating simple from complex — this is one of the few areas where provider clinical judgment and documentation carry the full weight of code selection. The documentation must reflect the nature and extent of treatment to support whichever code is assigned.
Includes
The following components and services are bundled into 30901 and cannot be separately billed:
- Application of topical anesthetic or vasoconstrictor prior to cautery/packing (e.g., lidocaine + oxymetazoline pledget insertion) — this preparatory step is integral to the procedure
- Silver nitrate cautery when applied for epistaxis control
- Electrocautery when used for epistaxis control
- Placement of anterior nasal packing (absorbable or non-absorbable) as part of the hemorrhage control
- Removal of packing placed at the same encounter (for absorbable packing that is left in; removal visit is separate and may be separately billable when medically necessary)
- Indirect or limited visualization of the nasal cavity using a nasal speculum as part of the procedure
- Application of topical hemostatic agents (Gelfoam, Surgicel, Floseal) as part of the hemorrhage control — the agent itself may be separately billed as a supply using HCPCS codes depending on payer policy, but the application service is bundled
- Post-procedure instructions and counseling within the 0-day global period
Excludes / Do Not Report Together
NCCI Bundles — Mutually Exclusive Codes
| Code | Description | NCCI Relationship to 30901 | Override Modifier |
|---|---|---|---|
| 30903 | Anterior epistaxis, complex | Mutually exclusive — cannot bill both anterior codes at same encounter; use only the most extensive (if complex criteria met, use 30903 only) | None — cannot override |
| 30905 | Posterior epistaxis, initial | 30901 is bundled INTO 30905 — if both anterior and posterior bleeds are treated at the same encounter, report only 30905 | None for same-side; 59/XE may apply in specific scenarios |
| 30906 | Posterior epistaxis, subsequent | Same bundling logic — 30901 is subsumed | 59/XE if separate encounter |
| 31231 | Diagnostic nasal endoscopy | Reverse bundle — 31231 bundles 30901 (unusual direction; see below) | Payer-specific |
The Reverse Bundle: 30901 and 31231
This is one of the most counterintuitive NCCI edits in ENT coding and generates significant confusion:
The Standard Rule: The NCCI typically bundles diagnostic procedures into surgical procedures — meaning when you perform a diagnostic scope and then treat the finding, you bill only the surgical code and the diagnostic scope is considered integral.
The Epistaxis Exception: Because 30901 has a lower relative value than 31231 (diagnostic nasal endoscopy), the NCCI bundles in the reverse direction — 31231 is listed as the column 1 code and 30901 is the column 2 code (bundled into 31231). This means:
- When a physician performs diagnostic nasal endoscopy (31231) followed by simple anterior cautery (30901), report 31231 only, because it has the higher value and 30901 is bundled into it
- When a physician performs diagnostic endoscopy followed by 30903, 30905, or 30906, report the surgical procedure code (30903/30905/30906), because all three have higher values than 31231 and the surgical codes are the column 1 codes in those edits
- In plain terms: 30901 is the only epistaxis code that pays less than diagnostic endoscopy (31231). For all other epistaxis codes, bill the surgical procedure. For simple cautery, bill the endoscopy if performed.
Additional Bundling and Coding Restrictions
| Code | Description | Rule |
|---|---|---|
| 31238 | Nasal endoscopy surgical, with hemorrhage control | Use 31238 when the endoscope is the active treatment instrument, not just for visualization; do not report 30901 with 31238; they describe the same service via different techniques |
| 30800/30801 | Ablation, soft tissue of inferior turbinates | Turbinate cautery/ablation is a separate, distinct procedure from epistaxis cautery — do not conflate; if cautery is performed specifically for epistaxis at one area AND turbinate ablation is performed as a separate intervention at a different site in the same session, carefully document both and verify payer policy on separate reporting |
| 99213-99215 | E&M on same date | Separately reportable with modifier -25 if a significant, separately identifiable E&M is documented; 30901 has a 0-day global period; see modifier section below |
When 30901 Cannot Be Reported — Important Negative Rules
Per the AMA CPT Assistant (July 2020): If the physician places a cotton pledget or gauze with topical anesthetic/decongestant into the nose for a short time to identify the bleeding site, then removes it with no ensuing bleeding identified and no cautery or packing left in place, 30901 is NOT reportable. The appropriate code is an E&M service only. You must have evidence of actual cautery performed or packing left in place to report any epistaxis control code.
Additional scenarios where 30901 is not reportable:
- Bleeding stopped with direct pressure alone, no cautery or packing
- Topical oxymetazoline spray alone achieved hemostasis with no other intervention
- Bleeding had already stopped by the time the patient was examined; no treatment performed
- Cautery was performed but for turbinate reduction, not epistaxis (use 30801 instead)
HCC (Hierarchical Condition Category)
| Field | Detail |
|---|---|
| HCC Mapped | No |
| Rationale | CPT 30901 is a procedure code. HCC risk adjustment is exclusively driven by ICD-10-CM diagnosis codes, not CPT codes. The procedure itself carries no HCC value. |
| HCC Opportunity via Diagnosis | The ICD-10-CM diagnosis codes reported with 30901 may carry HCC significance in certain clinical scenarios. Epistaxis itself (R04.0) is not an HCC code. However, when epistaxis is attributable to a systemic condition, coding that underlying etiology appropriately generates HCC credit. For example: hemorrhagic disorders (D65, D68.x), anticoagulant adverse effects (T45.515x), hereditary hemorrhagic telangiectasia — Osler-Weber-Rendu disease (I78.0), chronic liver disease with coagulopathy (K74.x + D65), and hematologic malignancies (C81-C96) may all be HCC-relevant underlying causes of epistaxis. Always code the underlying etiology when documented. |
wRVU (Work Relative Value Units)
CPT 30901 carries the following approximate RVU values based on the CMS Medicare Physician Fee Schedule:
| Component | Facility Setting | Non-Facility Setting |
|---|---|---|
| Work RVU (wRVU) | ~1.31 | ~1.31 |
| Practice Expense RVU | ~1.09 | ~2.79 (higher — physician bears supply/staff cost) |
| Malpractice RVU | ~0.07 | ~0.07 |
| Total RVU (facility) | ~2.47 | ~4.17 |
Approximate Medicare National Payment:
- Facility: ~85 (Total RVU ~2.47 × CF $32.35)
- Non-Facility: ~145 (Total RVU ~4.17 × CF $32.35)
Note
The non-facility rate is relevant when 30901 is performed in an office or clinic setting (the physician bears the cost of supplies and nursing). The facility rate applies when performed in the ED, hospital inpatient, or ASC setting. The non-facility rate is often significantly higher for minor procedures like 30901.
Code Family wRVU Comparison:
| CPT | Description | wRVU (approx.) |
|---|---|---|
| 30901 | Anterior, simple | ~1.31 |
| 30903 | Anterior, complex | ~2.42 |
| 31231 | Diagnostic nasal endoscopy | ~1.43 |
| 30905 | Posterior, initial | ~3.01 |
| 30906 | Posterior, subsequent | ~3.88 |
| 31238 | Endoscopic hemorrhage control | ~4.84 |
Note
30901 is the lowest-valued code in the epistaxis family and also carries a lower value than diagnostic nasal endoscopy (31231). This is the clinical basis for the reverse NCCI bundle discussed above. Always verify against the current year’s CMS MPFS Addendum B, as values are subject to annual revision.
Assistant Payable
| Field | Detail |
|---|---|
| Medicare Assistant-at-Surgery | No — Not Payable |
| Co-surgeon | Not applicable |
| Rationale | CPT 30901 is a minor procedure performed by a single physician, typically at bedside, in a clinic, or in an emergency department. No surgical assistant has any defined role in the performance of nasal cautery or limited anterior packing. Medicare’s assistant-at-surgery indicator for 30901 is 0 — assistant not payable under any circumstance, regardless of setting or patient complexity. |
| Commercial/Medicaid | No commercial payer or Medicaid program reimburses for an assistant during simple anterior epistaxis control. |
| Anesthesia Note | 30901 does not require general anesthesia and therefore does not have a standard anesthesia CPT crosswalk in the surgical sense. Local topical anesthesia is applied by the treating physician as part of the procedure. If a patient requires sedation for behavioral or medical reasons (rare), that is a separate clinical and billing matter. |
Global Period & Modifier Considerations
| Field | Detail |
|---|---|
| Global Period | 0 days |
| Implication | The fee for 30901 covers only the procedure itself on the date of service. No pre-operative or post-operative care is bundled. A separately documented E&M service may be billed on the same date. |
| Modifier -25 | Required when billing an E&M on the same date as 30901 for Medicare and most commercial payers. The E&M must be separately documented and represent a significant, separately identifiable service beyond the decision to perform and performance of the epistaxis control. Example: patient presents with epistaxis; physician takes a full history, examines the nasal cavity, documents assessment of underlying hypertension and anticoagulation status, then performs cautery — the E&M and 30901 may both be billed with modifier -25 on the E&M. |
| Modifier -50 | Bilateral — applicable to 30901 and 30903 (anterior codes only). If both nostrils are treated for anterior epistaxis at the same session, append modifier -50 (or use -RT/-LT per payer preference). Some payers want a single line with modifier -50; others prefer two lines with -LT on the second. Verify payer-specific billing rules. This generates two units of payment. Modifier -50 does NOT apply to 30905 or 30906 (posterior codes), which are inherently bilateral. |
| Modifier -RT / -LT | Document and append right or left side modifier per payer requirements. Many payers — particularly commercial payers — require laterality modifiers for 30901. Always document which nostril was treated in the chart note. |
| Modifier -59 / -XE | Use to separate a distinct procedural service from a bundled code when NCCI edits would otherwise prevent payment. In epistaxis coding, -59 or -XE may be used to separate same-day posterior packing (30906) from anterior treatment (30901) when performed at two distinct encounters on the same date. Document each encounter separately. |
| Modifier -76 | Repeat procedure by same physician. Use when the same provider performs the same epistaxis control procedure a second time on the same date (e.g., repeat anterior cautery after initial pack falls out). |
| Modifier -77 | Repeat procedure by different physician. Use when a second provider (e.g., on-call ED physician) repeats epistaxis control after the original treating provider’s intervention. |
Site of Service (SOS) Considerations
| Setting | Applicable | Notes |
|---|---|---|
| Office / Clinic | Yes — most common outpatient setting | Physician bears supply and staff costs; non-facility RVU applies; highest physician payment; billed on CMS-1500 |
| Emergency Department | Yes — very common | Facility rate applies (hospital bills separately under OPPS APC); physician bills professional component only; common inpatient-adjacent encounter |
| Hospital Inpatient (Bedside) | Yes — applicable | Facility rate applies; physician bills on CMS-1500; common in hospitalized patients on anticoagulation, with hematologic disorders, or post-procedure |
| Hospital Outpatient Department (HOPD) | Yes | Facility rate applies; hospital bills APC; physician bills professional component |
| Ambulatory Surgery Center (ASC) | Rarely needed | Minor procedure not typically requiring ASC; posterior bleeds more likely to end up in ASC; verify ASC coverage list for 30901 |
| Nursing Facility / SNF / Long-Term Care | Yes | Physician bills 30901; facility is not involved in separate billing for the procedure itself |
| Telehealth | No | Epistaxis control is a hands-on procedure; not performable via telehealth |
MS-DRG Assignment
CPT 30901 is a procedure code — MS-DRGs are assigned in the inpatient setting based on the combination of principal ICD-10-CM diagnosis, procedure codes, and CC/MCC status. In most cases, 30901 is performed in the outpatient or ED setting and does not drive an inpatient DRG. However, when a patient is admitted for epistaxis management, the following DRG considerations apply:
MDC 03 — Ear, Nose, Mouth, and Throat
R04.0 (Epistaxis) as principal diagnosis maps to MDC 03. The DRG assignment within MDC 03 will be determined by whether a qualifying OR procedure was performed and the CC/MCC profile:
| MS-DRG | Title | Notes |
|---|---|---|
| 153 | Otitis Media and URI with MCC | Applies to less severe ENT diagnoses including epistaxis with MCC |
| 154 | Otitis Media and URI without MCC | Epistaxis admitted without MCC or CC |
Important note:
Simple anterior epistaxis (30901) is generally not considered an OR procedure for MS-DRG purposes under the IPPS grouper. Posterior packing (30905/30906) or endoscopic control (31238) may carry OR procedure designation depending on the grouper version. When no OR procedure is performed, the DRG defaults to the medical DRG based on diagnosis alone.
When Epistaxis Requires OR-Level Intervention
If epistaxis is severe enough to require vascular ligation or embolization, different DRGs apply:
| MS-DRG | Title | Applies When |
|---|---|---|
| 168 | Major Respiratory System Diagnoses with Ventilator Support | Rarely — only if airway compromise with ventilator support |
| 163-168 | Major Chest / Respiratory Procedures | If arterial ligation or embolization performed |
Coagulopathy-Driven DRG Shifts
When epistaxis is the presenting sign of an underlying coagulopathy, hematologic malignancy, or other systemic condition, the principal diagnosis may shift to that underlying condition, completely changing the MS-DRG. For example:
- Epistaxis as the first presentation of newly diagnosed leukemia → Principal Dx: C91.x or C92.x → MDC 17 (Myeloproliferative Diseases) → dramatically higher DRG weight
- Epistaxis in a patient with hemophilia or Von Willebrand disease → Principal Dx: D66-D68.x → MDC 16 (Blood/Blood-Forming Organ Diseases) → different DRG family
- Epistaxis secondary to warfarin toxicity/adverse effect → may be coded as adverse effect (T45.515x) with epistaxis secondary → different sequencing and DRG implication
CC/MCC Impact for Secondary Diagnosis
When 30901 is performed and R04.0 is a secondary diagnosis, R04.0 itself is not a CC or MCC. It does not independently elevate the DRG tier. However, an underlying coagulopathy, hematologic disorder, or vascular malformation causing the epistaxis may function as a CC or MCC when coded as a secondary diagnosis.
Commonly Paired ICD-10-CM Diagnosis Codes
Always code the underlying etiology when documented, not just R04.0, as this captures a more complete clinical picture, supports medical necessity, and may affect DRG weight and HCC risk adjustment.

Present on Admission (POA)
CPT 30901 is a procedure code — POA indicators apply to ICD-10-CM diagnosis codes on inpatient claims, not to procedure codes. The principal and secondary diagnoses paired with 30901 will require appropriate POA assignment:
- R04.0 (Epistaxis) as principal diagnosis during inpatient admission → POA = Y if the epistaxis was the reason for admission
- POA = N if epistaxis develops during an inpatient stay for another reason (e.g., patient admitted for surgery and develops epistaxis post-operatively or due to a medication change)
- Underlying coagulopathy or hematologic diagnosis — assign POA based on whether the condition was present or newly identified during the admission
Coding Guidelines, Rules & Common Errors
Rule 1 — Cautery or Packing Must Actually Be Performed
Per the AMA CPT Assistant (July 2020): 30901 cannot be reported unless cautery was performed or packing was left in place. If the provider places a vasoconstrictor-soaked pledget temporarily to assess the bleeding, removes it after a few minutes, and the bleeding has stopped without cautery or retained packing, the service is an E&M only. This is a frequently misunderstood rule and a common overcoding compliance risk.
Rule 2 — Simple vs. Complex Is a Provider Judgment Call
CPT does not provide a bright-line numerical definition distinguishing 30901 (simple/limited) from 30903 (complex/extensive). The determination is made by the treating provider based on clinical difficulty, extent of intervention, and effort required. The chart documentation must reflect whichever level of complexity is billed. Auditors will look for language that supports “simple/limited” in 30901 charts and “complex/extensive/multiple areas/difficult to control” in 30903 charts.
Rule 3 — Do Not Bill Both Anterior Codes at the Same Encounter
If both simple and complex techniques were used on the same nostril in a single encounter (e.g., silver nitrate failed and the physician then placed a merocel tampon), report only 30903 (complex). NCCI bundles 30901 into 30903. You cannot report both.
Rule 4 — Anterior + Posterior = Posterior Code Only
If both anterior and posterior epistaxis are treated at the same encounter on the same side (e.g., provider places anterior packing first, then posterior packing), report only the posterior code (30905). NCCI bundles 30901 and 30903 into 30905. Report only the most extensive code for the same encounter.
Rule 5 — Bilateral Anterior = Modifier 50 (or RT/LT)
30901 and 30903 are unilateral codes. If both nostrils are treated for anterior epistaxis at the same session, append modifier -50 (bilateral) or report with -LT and -RT per payer preference. Failure to append the bilateral modifier when both sides are treated results in undercoding and lost revenue. Document which nostril(s) were treated.
Rule 6 — Posterior Codes Are Inherently Bilateral
Unlike anterior codes, 30905 and 30906 are bilateral by nature — posterior packing typically tamponades the entire posterior nasal space bilaterally. Do not append modifier -50 to 30905 or 30906.
Rule 7 — Same-Day E&M with Modifier -25
Because 30901 has a 0-day global period, an E&M service is separately reportable on the same date when it is clearly and separately documented. The E&M must represent a distinct, separately identifiable service beyond the epistaxis control itself. Without a separately identifiable E&M note (e.g., the physician only documents the cautery and nothing else), the E&M cannot be supported. Append modifier -25 to the E&M code on all Medicare and most commercial claims.
Rule 8 — Endoscopy for Visualization Only = 30901 (Not 31238)
When the physician uses a nasal endoscope solely to visualize the bleeding site before performing traditional cautery, report 30901 (or 30903/30905 as appropriate) — not 31238. The endoscope is a visualization tool in this scenario, not the treatment instrument. Report 31238 only when the endoscope is actively used to control the bleeding (e.g., endoscopic-guided bipolar cautery through the scope to a posterior bleeding point).
Rule 9 — Repacking by a Different Provider
If a patient has anterior packing placed in the ED by one provider, and an ENT later in the same day repacks the same nostril in the same location, the ENT may report 30901 with modifier -77 (repeat procedure by different physician), provided the clinical documentation supports that a distinct, medically necessary procedure was performed. The two providers bill under their respective NPIs.
Anesthesia Considerations
30901 does not require general, regional, or monitored anesthesia care (MAC) in standard practice. The procedure is performed under:
- Topical anesthesia — typically lidocaine 4% or cocaine 4% solution on cotton pledgets applied for 5-10 minutes prior to the procedure
- Topical vasoconstriction — oxymetazoline (Afrin) or phenylephrine spray to reduce mucosal engorgement and improve visualization
- No systemic anesthesia is typically required or expected
In rare circumstances (e.g., pediatric patients, severe phobia, combative patients), procedural sedation may be employed, but this is managed separately as a clinical and billing matter and does not change the CPT code for the procedure itself.
Coding Examples
Example 1 — Classic Office-Based Simple Silver Nitrate Cautery
A 34-year-old male presents to an ENT clinic with a 3-day history of intermittent right-sided epistaxis. He reports no anticoagulant use, no trauma, and no prior epistaxis treatment. On anterior rhinoscopy, a small vessel is identified at the right anterior nasal septum (Kiesselbach’s plexus). The mucosa is anesthetized with a lidocaine-soaked pledget for 5 minutes. Silver nitrate is applied to the bleeding vessel with a single stick, achieving immediate hemostasis. A small Gelfoam pledget is placed at the cauterized site. Procedure complete.
CPT: 30901-RT — Control nasal hemorrhage, anterior, simple, right side ICD-10-CM: R04.0 — Epistaxis Setting note: Office visit — non-facility RVU applies; higher payment rate E&M: If a separately identifiable E&M was performed (e.g., evaluation of hypertension, review of medications, new patient history), report 99202-99205-25 or 99212-99215-25 separately with modifier -25
Example 2 — Bilateral Anterior Cautery
A 28-year-old female presents with bilateral nosebleeds for 2 weeks. Examination reveals bilateral anterior septal erosions with oozing. Silver nitrate cautery is applied to both sides separately; each side responds promptly to a limited application.
CPT: 30901-50 — Control nasal hemorrhage, anterior, simple, bilateral (or report as 30901-LT and 30901-RT on separate lines depending on payer) ICD-10-CM: R04.0 — Epistaxis Note: Confirm payer billing preference for modifier -50 vs. two line items
Example 3 — E&M Plus Epistaxis Control on Same Day
A hypertensive patient presents to the ENT office for the first time with epistaxis. The physician performs a comprehensive new patient history and examination documenting uncontrolled hypertension, reviews current medications (amlodipine), and discusses long-term nasal hygiene. After the E&M, limited silver nitrate cautery is performed for a small anterior bleeding point.
CPT: 99205-25 — New patient E&M, high complexity, with modifier -25 CPT: 30901-LT — Control nasal hemorrhage, anterior, simple, left side ICD-10-CM: R04.0 — Epistaxis ICD-10-CM: I10 — Essential hypertension Key: Modifier -25 is critical; without it, the E&M will likely deny as bundled
Example 4 — Anterior Packing with Rhinorocket, Hospital ED
A 72-year-old male on warfarin presents to the ED with profuse left anterior epistaxis that has not responded to 20 minutes of direct pressure. The ED physician places a Rapid Rhino anterior balloon pack in the left nostril, inflates it per protocol, and achieves hemostasis. Suction and speculum examination confirmed anterior origin.
CPT: 30901-LT — Control nasal hemorrhage, anterior, simple (Note: A limited nasal balloon may still qualify as simple if the bleeding was controlled without escalating to 30903-level effort; if the physician documents the bleed as difficult to control or multiple attempts required, escalate to 30903) ICD-10-CM: R04.0 — Epistaxis ICD-10-CM: T45.515A — Adverse effect of anticoagulants, initial encounter ICD-10-CM: Z79.01 — Long-term use of anticoagulants POA: R04.0 = Y; T45.515A = Y
Example 5 — 30901 Escalates to 30903 Mid-Procedure
A 55-year-old male presents with right-sided epistaxis. The physician initially attempts silver nitrate cautery at a small anterior septal site; bleeding continues. The physician attempts a second application — still bleeding. A cotton tampon (Merocel) is then placed with complete anterior nasal packing. Total procedure time approximately 25 minutes. Provider documents “difficult-to-control anterior hemorrhage requiring extensive packing.”
CPT: 30903-RT — NOT 30901; escalate to complex because of documentation of extensive treatment and difficulty of control ICD-10-CM: R04.0 — Epistaxis Compliance note: Never bill both 30901 and 30903 for the same nostril at the same encounter; NCCI bundles 30901 into 30903 and the edit cannot be overridden
Example 6 — Anterior + Posterior on Same Day — Report Only Posterior
An ENT is called to the ED to manage epistaxis in a 68-year-old woman. Anterior silver nitrate cautery is attempted first (30901 level effort) but the bleeding origin appears posterior. Posterior nasal packing is then placed using a double-balloon epistaxis catheter.
CPT: 30905 — Posterior epistaxis control, initial — only this code (30901 is bundled into 30905 — do not report both) ICD-10-CM: R04.0 — Epistaxis Modifier: No bilateral modifier for 30905
Example 7 — Inpatient Epistaxis, Secondary to Thrombocytopenia
A 58-year-old male is admitted with fever, fatigue, and thrombocytopenia. During the admission workup, he develops bilateral anterior epistaxis. Hematology and ENT are consulted. ENT performs bilateral silver nitrate cautery at the bedside with prompt hemostasis of both anterior nasal cavities.
CPT: 30901-50 — Bilateral anterior epistaxis control, simple (billed by ENT physician) Principal Dx: D69.6 — Thrombocytopenia, unspecified (or more specific if established) Secondary Dx: R04.0 — Epistaxis Secondary Dx: (Additional secondary diagnoses per hematologic workup findings) POA: D69.6 = evaluate per documentation; R04.0 = N if developed during admission MS-DRG note: DRG governed by the principal hematologic diagnosis, not the epistaxis; MDC 16 (Diseases and Disorders of the Blood) rather than MDC 03
Example 8 — No Cautery/Packing = E&M Only (Not 30901)
A patient presents to an urgent care clinic with minimal left-sided epistaxis. The nurse applies oxymetazoline spray; by the time the physician enters, the bleeding has stopped. The physician examines the nose, finds no active bleeding, and counsels on nasal hygiene. No cautery, no packing placed.
CPT: 99213 or 99214 (E&M only, no procedure) (30901 is NOT reportable — no cautery performed, no packing left in place; per CPT guidelines and AMA CPT Assistant) ICD-10-CM: R04.0 — Epistaxis

Documentation Requirements for Audit Defense
Adequate documentation to support 30901 must include:
- Laterality — which nostril (right, left, or both)
- Location of bleeding — anterior septum, Little’s area, Kiesselbach’s plexus; specify if known; documentation that the bleed is confirmed as anterior in origin
- Method used — silver nitrate, electrocautery, type of packing material, hemostatic agent
- Extent of treatment — “limited,” “single application,” “one area,” “responded promptly”; language that supports the “simple” designation vs. 30903
- Hemostasis confirmed — document that active bleeding was controlled
- Packing left in place (if applicable) — type, duration expected, follow-up plan
- No posterior pack required — helps distinguish from 30905 in ambiguous cases
- Pre-procedure anesthesia — type of topical anesthetic applied
- If E&M also performed — must be separately documented with its own history, exam, and medical decision-making components to support modifier -25 billing
- Underlying etiology — document suspected or confirmed causes (hypertension, anticoagulation, dryness, trauma, etc.) to support appropriate secondary diagnosis coding
Quick Reference Summary

| Code | 30901 |
| Type | CPT Procedure Code |
| Full Descriptor | Control nasal hemorrhage, anterior, simple (limited cautery and/or packing) any method |
| Setting | Office, ED, Inpatient Bedside, HOPD |
| Anesthesia | Topical/local only |
| Global Period | 0 days |
| wRVU | ~1.31 (facility) |
| HCC | No (procedure code) |
| Assistant Payable | No (Medicare indicator 0) |
| Bilateral | Yes — unilateral code; use modifier -50 or -LT/-RT for bilateral anterior treatment |
| Posterior Bilateral? | No — modifier -50 does NOT apply to 30905/30906 |
| Must Have | Cautery performed OR packing left in place — no E&M only if no intervention |
| Do NOT add | 30903 for same nostril same encounter; use the most extensive code only |
| Key NCCI Bundle | 30901 bundles INTO 30905 (anterior and posterior same session → report 30905 only) |
| Reverse Bundle Alert | 31231 (diagnostic endoscopy) bundles 30901 — if endoscopy performed before simple cautery, bill 31231 (higher value); for 30903-30906, bill surgical code |
| Upgrade Path | If treatment was extensive → 30903; if posterior → 30905; if endoscopic control → 31238 |
| Common Errors | Billing 30901 when no pack/cautery placed; billing both 30901 + 30903; omitting modifier -50 for bilateral; not appending modifier -25 to same-day E&M |
A few things that are particularly worth flagging for your ENT inpatient and outpatient work with this one:
The reverse NCCI bundle with 31231 is genuinely counterintuitive and catches experienced coders off guard. Because 30901 has a lower wRVU than diagnostic nasal endoscopy, the bundle runs backward — 31231 is the column 1 code and 30901 gets swallowed. For every other epistaxis code (30903 through 30906), the surgical procedure is higher and the standard rule applies.
The bilateral modifier rule asymmetry is also a common source of errors: anterior codes (30901, 30903) are unilateral and need modifier -50 or LT/RT when both sides are treated; posterior codes (30905, 30906) are inherently bilateral by design and modifier -50 should never be appended to them.
And the “no cautery/packing = E&M only” rule from the 2020 AMA CPT Assistant guidance is the single most important compliance point — a significant number of 30901 claims in the office setting lack documentation that any actual intervention was retained or performed, making them undefendable on audit.
