Quick Reference
wRVU: 0.63 | Global Period: 000 (Same Day) | Assistant Payable: ❌ No | Bilateral Indicator: 3
📋 Clinical Description
CPT 11305 describes the shave removal of a single epidermal or dermal lesion located on the scalp, neck, hands, feet, or genitalia, with a lesion diameter of 0.5 cm or less, including local anesthesia. As with the entire 11300 shave removal family, the provider uses a tangential slicing technique — a blade or electrosurgical instrument held at an angle parallel or oblique to the skin surface — to remove the raised or exophytic portion of the lesion without creating a full-thickness skin defect. The key distinction between 11305 and its closest sibling 11300 is anatomic site, not technique or size — 11305 applies exclusively to the scalp, neck, hands, feet, and genitalia, while 11300 applies to the trunk, arms, and legs. When a lesion is located on the face, ears, eyelids, nose, lips, or mucous membranes, the correct code family is 11310-11313.
Raised benign epidermal and dermal lesions at these anatomic sites — including seborrheic keratoses, benign nevi, verrucae (including plantar warts on the feet), and skin tags — are the most common indications for CPT 11305. These sites are coded separately from the trunk and extremities because they carry distinct anatomic complexity, cosmetic sensitivity, and procedural considerations; for example, scalp lesions involve greater vascularity and hair-bearing tissue, plantar foot lesions involve weight-bearing skin with greater hyperkeratosis, and genital lesions carry unique patient care and documentation considerations. When a provider removes a lesion at these sites and submits tissue for pathology, the pathology interpretation is separately billable under 88302-88309 by the interpreting pathologist — it is not bundled into 11305.
This procedure may be performed in the following clinical contexts:
- Scalp Seborrheic Keratosis or Nevus — Shave removal of a raised, pigmented, or hyperkeratotic lesion on the scalp; the scalp’s rich vascular supply increases bleeding risk, and the hair-bearing environment requires careful hemostasis documentation; shave technique is preferred over full excision for most superficial scalp lesions to avoid hair loss
- Neck Lesion — Skin Tag or Benign Growth — Shave or snip removal of a pedunculated acrochordon or raised benign lesion on the neck; neck lesions are frequently irritated by clothing or jewelry, providing medical necessity documentation for symptomatic removal
- Plantar Wart (Verruca Plantaris) — Hand or Foot — Shave removal of a verruca on the plantar surface of the foot or palmar surface of the hand after failed conservative treatment (cryotherapy, topical agents); plantar warts present with unique coding considerations — B07.0 (plantar wart) is the most specific ICD-10-CM code, distinct from B07.9
- Verruca Vulgaris — Hand — Common wart on the dorsal hand or finger; shave removal when destruction has failed or when tissue diagnosis is desired
- Genital Lesion — Benign Condyloma or Fibroepithelial Polyp — Shave or snip removal of a benign genital skin lesion; careful documentation of clinical impression is essential; condyloma acuminata (HPV-related anogenital warts) may have specific coding and treatment pathway distinctions from other genital lesions
🔬 Anatomical & Procedural Considerations
| Technique Variant | Mechanism / Steps | Key Notes |
|---|---|---|
| Tangential Shave — Blade | Scalpel blade, DermaBlade, or razor blade held at low angle; lesion undercut at the base with a smooth tangential stroke | Most common technique; document instrument, lesion site, measured diameter, and depth of removal; scalp procedures require particular attention to hemostasis given vascularity |
| Snip Excision | Scissors used to snip a pedunculated or stalked lesion at its base | Appropriate for skin tags on the neck or pedunculated genital lesions; considered a variant of shave removal; note must document the technique |
| Electrosurgical Shave | Loop electrode or electrocautery used to simultaneously remove and cauterize the lesion base | Useful for vascular scalp or neck lesions; distinguish from destruction — if tissue is ablated without a removable specimen, a destruction code (17000-17286) applies instead |
| Curettage Following Shave | Curette used after initial shave to smooth the wound base | Included in 11305 — not separately reportable; document as part of the single procedure |
| Plantar Wart — Paring + Shave | Initial debulking of hyperkeratotic overlying tissue (paring) followed by shave removal of the wart base | Paring is included in the shave removal service; do not separately report a paring code (11055-11057) with 11305 for the same lesion on the same date |
Clinical Pearl
The anatomic site documented in the procedure note is the single most critical factor determining whether 11305, 11300, or 11310 is the correct code — not the technique or the diagnosis. When a lesion is on the neck, it is 11305; when on the upper back, it is 11300; when on the face or eyelid, it is 11310. This distinction is frequently missed when coders default to 11300 for all shave removals regardless of site. Audit risk is real — the procedure note must clearly state the anatomic location of each lesion, and the code selected must match that documented site exactly. When multiple lesions are removed from different site categories in the same session (e.g., one on the neck and one on the trunk), each lesion is coded from its own site-specific family and billed as a separate line item.
✅ Procedure Includes…
- Pre-procedure clinical assessment of the lesion including site, measured diameter, and morphology documentation
- Local anesthesia — topical or injectable (explicitly bundled into 11305 per the CPT descriptor; never separately reportable)
- Tangential shave, snip, or electrosurgical removal of the epidermal or dermal lesion
- Hemostasis by electrocautery, chemical agent (e.g., aluminum chloride, Monsel’s solution), or pressure
- Application of wound dressing
- Specimen preparation and submission for pathology when performed (pathology interpretation separately reportable under 88302-88309 by the interpreting provider)
❌ Excludes / Do Not Report Together
| Code | Description | Relationship to 11305 |
|---|---|---|
| 11306 | Shave removal, scalp/neck/hands/feet/genitalia; lesion diameter 0.6-1.0 cm | Same site family as 11305 but larger lesion; select based on clinically measured lesion diameter — never report 11305 and 11306 for the same lesion |
| 11307 | Shave removal, scalp/neck/hands/feet/genitalia; lesion diameter 1.1-2.0 cm | Larger diameter tier; same site family |
| 11308 | Shave removal, scalp/neck/hands/feet/genitalia; lesion diameter over 2.0 cm | Largest diameter tier in this site family |
| 11300 | Shave removal, trunk/arms/legs; 0.5 cm or less | Anatomically distinct code for trunk, arms, and legs — same size tier as 11305 but different body site; do not use 11300 for lesions on the scalp, neck, hands, feet, or genitalia |
| 11310 | Shave removal, face/ears/eyelids/nose/lips/mucous membrane; 0.5 cm or less | Anatomically distinct code for face, ears, eyelids, nose, lips, and mucous membranes; do not use 11305 for facial or eyelid lesions |
| 11420 | Excision, benign lesion; scalp/neck/hands/feet/genitalia; excised diameter 0.5 cm or less | Full-thickness excision requiring repair; mutually exclusive with 11305 by technique and depth — shave stays within epidermis/dermis, excision is full-thickness; never report both for the same lesion |
| 11055-11057 | Paring or cutting of benign hyperkeratotic lesion | Paring of a plantar callus or corn at the same site as an 11305 shave removal on the same date is bundled — do not report separately for the same lesion |
| 11100 | Biopsy, skin; single lesion | When the primary intent is diagnostic tissue sampling, 11100 is correct; when the primary intent is removal of a benign lesion, 11305 is correct; intent documented in the procedure note drives code selection |
| E/M codes (992xx / 920xx) | Office visit, any level | Separately reportable only when modifier -25 is appended to the E/M code, documenting a significant, separately identifiable E/M service beyond the routine pre-procedure lesion assessment |
Bundling Alert — Global Period is 000, Not 010 or 090
CPT 11305 carries a 000 global period (same-day only). The global package includes same-day pre- and post-procedure services only — any follow-up visit after the procedure date is separately billable without a modifier. Do not apply a 10-day or 90-day mental block to shave removal codes based on habit from other surgical code families. When a patient is seen the same day for an unrelated condition, modifier -24 applies to the E/M with explicit documentation that the visit is unrelated to the shave removal. The most common audit finding is billing a same-day E/M without modifier -25 on the E/M code, or with insufficient documentation to justify the separate E/M beyond the pre-procedure lesion assessment.

Multiple Lesion Billing Rules
Like 11300, CPT 11305 has no add-on code. Each lesion removed by shave technique is reported as its own separate primary code line, selected based on the individual lesion’s site and clinically measured diameter. When multiple shave removals are performed in the same session — including lesions across different site categories (e.g., one neck lesion billed as 11305 and one trunk lesion billed as 11300) — each code after the highest-valued procedure is subject to the multiple procedure payment reduction under modifier -51. Document each lesion individually with its own site, measured diameter, and technique.
🏷️ Modifier Reference
| Modifier | Name | When to Apply |
|---|---|---|
| -25 | Significant, Separately Identifiable E/M | Applied to the E/M code — not 11305 — when a separately identifiable office visit is performed on the same date; documentation must support a distinct, medically necessary evaluation with its own history, exam, and MDM beyond the pre-procedure lesion assessment |
| -24 | Unrelated E/M During Postoperative Period | Applied to the E/M code when the patient is seen same day for a condition entirely unrelated to the shave removal; document the unrelated nature explicitly in the note |
| -51 | Multiple Procedures | When 11305 is performed alongside other surgical procedures in the same session; apply to the lower-valued procedure code; each additional shave removal is a separate primary code subject to -51 |
| -52 | Reduced Services | Procedure partially completed (e.g., partial lesion removed due to patient intolerance or bleeding); document clinical reason |
| -53 | Discontinued Procedure | Procedure stopped after initiation due to patient safety concern; document reason thoroughly |
| -59 | Distinct Procedural Service | When 11305 is reported alongside another procedure that a payer inappropriately bundles; documents distinct lesion site or independent service |
| -XS | Separate Structure | Preferred X-modifier over -59 when billing 11305 for an anatomically distinct site from another same-day procedure |
| -XU | Unusual Non-Overlapping Service | When a payer inappropriately bundles 11305 with a clearly distinct, non-overlapping service |
🩺 Common ICD-10-CM Pairings
Benign Epidermal and Dermal Lesions — Scalp and Neck
| ICD-10 Code | Description | HCC? | Clinical Notes |
|---|---|---|---|
| L82.1 | Other seborrheic keratosis | ❌ No | Most common diagnosis paired with scalp/neck shave removal; document whether symptomatic (irritated, bleeding, catching on hair or collar) — medical necessity documentation required for payer reimbursement |
| L82.0 | Inflamed seborrheic keratosis | ❌ No | Inflamed or irritated seborrheic keratosis; provides stronger medical necessity support than L82.1 — explicitly documents a symptomatic lesion |
| D22.4 | Melanocytic nevi of scalp and neck | ❌ No | Clinically benign-appearing nevus on scalp or neck; site-specific code; note: shave technique is discouraged for pigmented lesions with atypical features — document clinical impression as benign before selecting shave over excisional biopsy |
| D23.4 | Other benign neoplasm of skin of scalp and neck | ❌ No | Benign dermal lesion on scalp or neck not classifiable as a nevus or keratosis; use when clinical impression is benign but diagnosis is not more specifically classifiable |
Benign Lesions — Hands and Feet
| ICD-10 Code | Description | HCC? | Clinical Notes |
|---|---|---|---|
| B07.0 | Plantar wart | ❌ No | Verruca plantaris on the plantar foot surface; most specific code for plantar wart — use over B07.9 when the plantar location is documented; common indication for 11305 after failed cryotherapy |
| B07.9 | Viral wart, unspecified | ❌ No | Common wart on the hand or foot when site is not further specified; use B07.0 for plantar wart specifically |
| D22.60 | Melanocytic nevi of unspecified upper limb, including shoulder | ❌ No | Clinically benign nevus on the hand or wrist; note that hand falls in the 11305 site family — not 11300 |
| D23.60 | Other benign neoplasm of skin of unspecified upper limb, including shoulder | ❌ No | Benign lesion on the hand not classified as a nevus; assign lateralized code when side is documented |
| L87.0 | Keratosis follicularis et parafollicularis in cutem penetrans | ❌ No | Perforating dermatosis on hands or feet requiring shave for diagnostic/therapeutic removal; uncommon but site-appropriate |
Lesions — Genitalia
| ICD-10 Code | Description | HCC? | Clinical Notes |
|---|---|---|---|
| A63.0 | Anogenital (venereal) warts | ❌ No | HPV-related condyloma acuminata at genital site; document the specific genital site; when condylomata are removed by shave or snip at the anogenital skin, 11305 may apply for small lesions — distinguish from condyloma destruction codes |
| D29.9 | Benign neoplasm of male genital organ, unspecified | ❌ No | Benign genital skin lesion in male patients; assign site-specific code when documented |
| D28.9 | Benign neoplasm of female genital organ, unspecified | ❌ No | Benign genital skin lesion in female patients; assign site-specific code when documented |
| L82.1 | Other seborrheic keratosis | ❌ No | Seborrheic keratosis on genital skin; document site specifically in the procedure note |
Uncertain or Pre-Pathology Diagnosis
| ICD-10 Code | Description | HCC? | Clinical Notes |
|---|---|---|---|
| D48.5 | Neoplasm of uncertain behavior of skin | ❌ No | When clinical impression is uncertain and tissue is submitted for pathology; do not assign a confirmed malignancy code prior to pathology results — code to the presenting clinical finding at time of service |
| Z12.83 | Encounter for screening for malignant neoplasm of skin | ❌ No | Use as principal diagnosis only when the encounter is a screening visit in an asymptomatic patient; when a specific symptomatic lesion drives the visit, the lesion diagnosis is the principal code |
| Z85.828 | Personal history of other malignant neoplasm of skin | ❌ No | Prior skin malignancy history used as additional diagnosis to support medical necessity for surveillance lesion removal |
Coding Specificity Reminder
The most common specificity gap for 11305 ICD-10-CM pairings involves site-specific laterality in the D22.- and D23.- code families (e.g., D22.61 — right upper limb vs. D22.60 — unspecified upper limb) and using B07.0 (plantar wart) over B07.9 (unspecified viral wart) when the plantar location is documented. The procedure note is your primary documentation source — when it documents “right hand” or “plantar surface, left foot,” use those details to assign the most specific code available. ICD-10-CM specificity requirements are not optional; query the provider when site documentation is absent before defaulting to unspecified codes.
🏥 MS-DRG Considerations (Inpatient)
Inpatient Coding Reminder
CPT 11305 is performed exclusively in the outpatient or office setting. There are no routine MS-DRG assignments for this procedure — inpatient admission for shave removal of a skin lesion at the scalp, neck, hand, foot, or genitalia would not be supported by any payer, MAC, or utilization review body. If a patient undergoing an inpatient admission for an unrelated diagnosis also has a lesion shave-removed at one of these sites during the stay, an ICD-10-PCS Excision code under Body System H (Skin and Breast) with qualifier Z (No Qualifier) is assigned for coding completeness but will have no independent impact on DRG grouping.
🔧 ICD-10-PCS Equivalents (Inpatient Facility Coding)
Note
Inpatient PCS coding for shave removal at these sites uses the Excision root operation (character B) under Body System H (Skin and Breast) with the External approach (X) and qualifier Z (No Qualifier) for therapeutic removal. Qualifier X (Diagnostic) is used when the intent is purely diagnostic tissue sampling. PCS does not differentiate shave technique from full-thickness excision at the code level — both use the Excision root operation; the technique distinction exists in the CPT system. Assign the PCS code corresponding to the documented anatomic body part site per the ICD-10-PCS Body Part Key.
| PCS Code | Full Description | Site |
|---|---|---|
0HB0XZZ | Excision of Scalp Skin, External Approach | Scalp lesion shave removal |
0HB4XZZ | Excision of Neck Skin, External Approach | Neck lesion shave removal |
0HBGXZZ | Excision of Right Hand Skin, External Approach | Right hand lesion shave removal |
0HBHXZZ | Excision of Left Hand Skin, External Approach | Left hand lesion shave removal |
0HBNXZZ | Excision of Right Foot Skin, External Approach | Right foot lesion shave removal |
0HBPXZZ | Excision of Left Foot Skin, External Approach | Left foot lesion shave removal |
0HBMXZZ | Excision of Perineum Skin, External Approach | Genital/perineal region lesion shave removal |
PCS Character Analysis — 0HB0XZZ
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical |
| 2 | Body System | H | Skin and Breast |
| 3 | Root Operation | B | Excision (cutting out or off, without replacement, a portion of a body part) |
| 4 | Body Part | 0 | Scalp Skin |
| 5 | Approach | X | External |
| 6 | Device | Z | No Device |
| 7 | Qualifier | Z | No Qualifier |
PCS Qualifier: No Qualifier (Z) vs. Diagnostic (X)
- Use qualifier Z (No Qualifier) when the shave removal is performed for therapeutic lesion removal — this is the inpatient PCS equivalent of CPT 11305
- Use qualifier X (Diagnostic) when the intent is diagnostic tissue sampling for histopathologic examination — this is the inpatient PCS equivalent of CPT 11100
- When a shave removal is performed and tissue is simultaneously submitted for pathology, the primary intent documented in the operative note drives qualifier selection; therapeutic removal with incidental pathology submission = qualifier Z; biopsy with incidental complete removal = qualifier X
📝 Coding Examples
Example 1 — Office: Plantar Wart, Right Foot, Shave Removal After Failed Cryotherapy
Clinical Scenario: A 29-year-old female presents to her dermatologist for management of a persistent plantar wart on the right heel that has failed two cryotherapy sessions. Examination reveals a 0.4 cm endophytic verrucous lesion on the plantar surface, right heel, with a central black dot pattern consistent with verruca plantaris. The provider documents: “Shave removal performed under local anesthesia with scalpel blade; lesion 0.4 cm diameter, plantar surface right heel; specimen submitted for pathology; base cauterized with electrocautery; dressing applied.” No separately documented E/M beyond lesion assessment.
| Field | Code | Rationale |
|---|---|---|
| CPT | 11305 | Shave removal, scalp/neck/hands/feet/genitalia (foot); lesion diameter 0.4 cm — within the 0.5 cm or less tier; local anesthesia included in descriptor |
| PDx | B07.0 | Plantar wart — most specific code for plantar location; use over B07.9 when plantar site is documented |
Note
The pathology interpretation is separately billable by the pathologist under 88305 (surgical pathology, Level IV — skin lesion) and is not bundled into CPT 11305. If the dermatologist also reads and documents the pathology results personally, they may separately bill under the appropriate surgical pathology code. The prior failed cryotherapy sessions (each with their own 000 global periods) do not restrict billing for this visit.
Example 2 — Office: Scalp Nevus and Neck Skin Tag, Same Visit, With Separate E/M
Clinical Scenario: A 52-year-old male presents for a skin check. The provider performs shave removal of a 0.3 cm benign-appearing pigmented nevus on the scalp and a 0.4 cm symptomatic skin tag on the posterior neck. Both specimens are submitted for pathology. The provider also documents a separately identifiable E/M addressing a new complaint of scalp pruritus, with distinct history, dermatologic examination findings, and medical decision-making documented separately from the shave removal procedures.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 99213--25 | Separately identifiable E/M for new scalp pruritus complaint — modifier -25 on the E/M code; distinct documentation supports a separate evaluation |
| CPT 2 | 11305 | Shave removal, scalp (scalp/neck/hands/feet/genitalia site family); 0.3 cm nevus — 0.5 cm or less tier |
| CPT 3 | 11305--51 | Shave removal, neck (scalp/neck/hands/feet/genitalia site family); 0.4 cm skin tag — same site family, same size tier; -51 applied as second procedure |
| PDx | D22.4 | Melanocytic nevi of scalp and neck — primary lesion (scalp nevus) |
| SDx | L82.1 | Other seborrheic keratosis / skin tag — posterior neck lesion; if documented as acrochordon, L91.8 may also be considered |
| SDx | L29.9 | Pruritus, unspecified — supports the separately identifiable E/M for scalp pruritus |
Warning
Modifier -25 belongs on the E/M code, never on 11305. Both lesions here fall within the same 11305 site family (scalp and neck are both in the scalp/neck/hands/feet/genitalia group), so both are coded as 11305. If one lesion had been on the neck and another on the trunk, you would report 11305 for the neck lesion and 11300 for the trunk lesion — mixing site families is appropriate when documented correctly, and each code is subject to -51 for the lower-valued line.
Example 3 — Office: Multiple Sites, Cross-Family Billing, Lesion Size Documentation
Clinical Scenario: A 61-year-old male presents for shave removal of three lesions: a 0.4 cm irritated seborrheic keratosis on the right posterior neck, a 0.6 cm seborrheic keratosis on the left forearm, and a 0.5 cm benign-appearing lesion on the right cheek. The provider documents each lesion site, clinical impression, and measured diameter separately. All three specimens are submitted for pathology. No separately identifiable E/M is performed.
| Field | Code | Rationale |
|---|---|---|
| CPT 1 | 11305 | Shave removal, neck (scalp/neck/hands/feet/genitalia); 0.4 cm — 0.5 cm or less tier; highest wRVU in this session |
| CPT 2 | 11310--51 | Shave removal, face/ears/eyelids/nose/lips (cheek = face); 0.5 cm — 0.5 cm or less tier; -51 applied |
| CPT 3 | 11301--51 | Shave removal, trunk/arms/legs (left forearm = arm); 0.6 cm — 0.6-1.0 cm tier; -51 applied |
| PDx | L82.0 | Inflamed seborrheic keratosis — neck lesion, symptomatic; primary diagnosis for visit |
| SDx | L82.1 | Other seborrheic keratosis — left forearm lesion |
| SDx | D48.5 | Neoplasm of uncertain behavior of skin — right cheek lesion if clinical impression is uncertain pending pathology |
Note
Global period reminder: Each of these three procedures carries a 000 global period — same day only. If the patient returns any subsequent day for a wound check or to review pathology results, that visit is separately billable as an E/M. Note the cross-family coding in this example: the neck lesion is 11305, the cheek lesion is 11310, and the forearm lesion is 11301 — each code is selected from the family matching its documented anatomic site, regardless of technique. This is correct coding practice and reflects the AMA’s intent in separating the shave removal family by site.
⚠️ Common Coding Pitfalls
-
Using 11300 for Scalp, Neck, Hand, or Foot Lesions: CPT 11300 applies only to the trunk, arms, and legs. Defaulting to 11300 for all shave removals regardless of site is the single most common site-specificity error in this code family. A shave removal on the neck is 11305; on the scalp is 11305; on the hand is 11305; on the face is 11310. The procedure note’s documented anatomic site must drive code selection — when the note says “neck,” the code must be 11305.
-
Selecting the Wrong Size Tier Based on Pathology Specimen Size: The lesion diameter that determines the correct tier (11305 vs. 11306 vs. 11307 vs. 11308) is the clinically measured diameter at the time of the procedure, not the pathology specimen size. Pathology specimens routinely shrink after fixation. Document the pre-removal clinical measurement in the procedure note — this is your audit defense if a payer challenges the tier selected.
-
Billing Local Anesthesia Separately: The CPT descriptor for 11305 explicitly includes local anesthesia. Separately reporting a local anesthetic injection code for the same lesion on the same date is an NCCI bundling violation. This is among the most commonly cited billing errors in dermatology and primary care lesion removal audits.
-
Reporting 11305 and an Excision Code for the Same Lesion: Shave removal (11305) and excision codes (11420-11426 for benign lesions at this site family) are mutually exclusive for the same lesion — they describe different techniques and depths. Assigning both for the same lesion is an NCCI bundling violation. The documented technique drives the code selection: shave (tangential, within epidermis/dermis) → 11305 series; excision (full-thickness, with margins) → 11420 series.
-
Placing Modifier -25 on the Procedure Code Instead of the E/M: Modifier -25 must be appended to the E/M service code, not to CPT 11305. This error appears frequently in dermatology audits. The E/M documentation must independently support a significant, separately identifiable evaluation with its own history, exam, and MDM — the pre-procedure lesion check alone is bundled into 11305 and does not qualify.
-
Failing to Apply -51 for Multiple Shave Removals: The shave removal family has no add-on code. Each additional lesion beyond the highest-valued procedure in the same session is a separately coded primary code subject to the multiple procedure reduction under modifier -51. Omitting -51 on lower-valued lines can result in claim rejection or overpayment findings; applying it incorrectly to the wrong line (highest-valued code instead of lower-valued) creates a reimbursement shortfall.
