Crystal's Coder Hub🩹 CPT 10061 — Incision and Drainage of Abscess (Complicated or Multiple)
Quick Reference
wRVU: 1.22 | Global Period: 010 (10 days) | Assistant Payable: ❌ No | Bilateral Indicator: 0
📋 Clinical Description
CPT 10061 describes incision and drainage of an abscess that is either complicated in nature or involves multiple separate lesions treated in the same session. The procedure requires more extensive surgical judgment and effort than 10060 — typically involving deep probing, breakdown of multiple loculations, counter-incisions, extensive packing, or drainage of more than one discrete abscess in the same encounter. The key differentiator from 10060 is operative complexity and/or multiplicity: if the surgeon documents multiple abscesses, multiple incisions, extensive loculation breakdown, or significant depth, 10061 is the appropriate code.
Suppurative hidradenitis (hidradenitis suppurativa, HS) is a chronic, recurrent inflammatory disease of the apocrine gland-bearing skin (axilla, groin, perineum, inframammary) causing painful nodules, abscesses, sinus tracts, and scarring. Chronic or recurrent HS with confluent or tunneling disease is among the most common “complicated” presentations justifying 10061 over 10060. When HS requires wide excision of affected skin rather than I&D, higher-level surgical excision codes apply instead.
This procedure may be performed in the following clinical contexts:
- Multiple discrete abscesses (same session) — Two or more separate abscess lesions treated at the same operative session, each requiring individual incision and drainage.
- Complicated single abscess with extensive loculations — A single large abscess requiring multiple counter-incisions or aggressive probing and breakdown of fibrous loculations throughout the cavity.
- Chronic or recurrent suppurative hidradenitis — Active HS nodules that are confluent, tunneling, or involve multiple adjacent skin areas in the axilla, groin, or perineum.
- Deep subcutaneous abscess — An abscess extending into deeper subcutaneous fat or approaching fascial planes, requiring more extensive dissection than a superficial collection.
- Complicated periurethral or scrotal abscess (Urology) — Loculated scrotal or periurethral abscess without frank Fournier’s gangrene; extensive probing and packing distinguishes this from simple I&D.
🔬 Anatomical & Procedural Considerations
| Feature | Description | Coding Impact |
|---|---|---|
| Multiple lesions | Two or more separately fluctuant abscesses incised and drained in same session | Hallmark indicator for 10061 vs. 10060; document each lesion separately |
| Multiple incisions / counter-incisions | More than one incision made into a single complex cavity | Must be documented; single-incision drainage = 10060 |
| Loculation breakdown | Blunt dissection through fibrous septae throughout the cavity | Must be explicitly documented as “extensive” to differentiate from simple probing |
| Depth | Cavity approaches fascia or involves thick subcutaneous fat | Supports “complicated” descriptor; note depth in operative note |
| Packing volume / technique | Large-volume or through-and-through packing (Penrose drain) | Consistent with but not exclusive to complicated I&D |
Clinical Pearl
The operative note must use language that explicitly supports “complicated” — words like “multiple incisions,” “extensive loculations,” “counter-incisions,” “multiple separate abscesses,” or “deep subcutaneous extension” are what auditors look for. A routine I&D note that says only “incision made, pus expressed, packed” will not survive a downcode challenge if 10061 is billed. When in doubt, query the surgeon to clarify complexity in the documentation.
✅ Procedure Includes
- Pre-procedure assessment and planning (bundled)
- Local or regional anesthetic administration
- Multiple incisions and/or counter-incisions as required
- Extensive blunt exploration and breakdown of loculations
- Evacuation of purulent material from all cavities
- Cavity irrigation (all sites)
- Through-and-through or extensive wound packing
- Application of dressings
- Standard post-procedure wound care within the 10-day global window
❌ Excludes / Do Not Report Together
| Code | Description | Relationship to 10061 |
|---|---|---|
| 10060 | I&D of abscess; simple or single | Report 10061 instead when complexity or multiplicity is documented — never report both for the same site same session |
| 10140 | Incision and drainage of hematoma, seroma, or fluid collection | Non-infectious fluid collections — distinct code; do not use 10061 for post-surgical seromas or hematomas |
| 11400–11446 | Excision of benign skin lesion | When HS or cyst requires excision (not just I&D), excision codes replace I&D codes |
| 11900–11901 | Injection into skin lesion | Intralesional steroid injection is a distinct service and may be separately reportable with appropriate documentation |
| 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 assessment |
Warning
Bundling Alert — Global Period is 010, Not 000 or 090 10061 carries a 10-day global period, identical to 10060. Follow-up visits for wound checks, packing changes, and drain management within 10 days are bundled. Audit risk is heightened for 10061 because the higher wRVU (1.22 vs. 0.70) makes it a more frequent target for post-payment review. Ensure operative documentation fully supports “complicated or multiple” before billing.

Bilateral Billing Rules
10061 has a bilateral indicator of 0 and is not subject to standard bilateral reduction rules. When multiple abscesses are treated at distinct anatomic sites in the same session, document each site separately. Because 10061 captures multiple lesions in a single encounter by definition, do not compound-bill 10061 + 10060 for “one complicated + one simple” abscess in the same session — one code captures the entire encounter.

🩺 Common ICD-10-CM Pairings
Complicated / Multiple Abscess
| ICD-10 Code | Description | HCC? | Clinical Notes |
|---|---|---|---|
| L02.211 | Cutaneous abscess of neck | ❌ No | High-relevance OTO code; document specific neck region (anterior triangle, posterior triangle, submandibular); multiple neck abscesses are common in OTO patients |
| L02.91 | Cutaneous abscess, unspecified | ❌ No | Last resort — query provider for site when absent from documentation |
| L73.2 | Hidradenitis suppurativa | ❌ No | Most specific HS diagnosis code; document site (axilla, groin, perianal) as additional specificity in the note |
| L03.311 | Cellulitis of abdominal wall | ❌ No | When complicated abscess involves the abdominal wall with surrounding cellulitis |
Etiology and Organism Codes
| ICD-10 Code | Description | HCC? | Clinical Notes |
|---|---|---|---|
| B95.62 | MRSA as the cause of diseases classified elsewhere | ❌ No | Report as additional when MRSA documented as causative organism; critical for infection control and antibiotic stewardship |
| B95.61 | MSSA as the cause of diseases classified elsewhere | ❌ No | Report when MSSA is specifically identified |
| B96.89 | Other specified bacterial agents | ❌ No | Report for polymicrobial or other specified organisms not covered by B95 codes |
Coding Specificity Reminder
For 10061, the most commonly missed ICD-10-CM axis is site specificity and organism documentation. The operative note should document which anatomic sites are involved and, when cultures are available, which organism was identified. When HS is the diagnosis, document stage and location — AAPC recommends providers use a recognized staging system (e.g., Hurley) to support medical necessity for surgical management. ICD-10-CM specificity requirements are not optional.
🏥 MS-DRG Considerations (Inpatient)
Inpatient Coding Reminder
CPT 10061 is performed primarily in the outpatient setting, but complicated abscess presentations — particularly in Urology (early Fournier’s gangrene) and OTO (Ludwig’s angina, deep neck space abscess) — may require inpatient admission. In those cases, ICD-10-PCS Drainage codes are assigned, and the principal diagnosis (e.g., L02.211, Cutaneous abscess of neck) will group to MDC 9 — Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast under DRG 573–575. CC/MCC status (e.g., MRSA documentation — B95.62 is a CC) meaningfully affects DRG tier.
🔧 ICD-10-PCS Equivalents (Inpatient Facility Coding)
Note
When assigned inpatient, the root operation is Drainage (9) — taking or letting out fluids and/or gases from a body part. Multiple PCS codes are assigned when multiple distinct body sites are drained. Approach is External (X) for skin-level I&D.
| PCS Code | Full Description | Applicable Scenario |
|---|---|---|
0H9NXZZ | Drainage, Skin, Trunk, External Approach, No Device, No Qualifier | Complicated abscess of trunk/torso |
0H95XZZ | Drainage, Skin, Neck, External Approach, No Device, No Qualifier | Complicated neck abscess (OTO) |
0H9PXZZ | Drainage, Skin, Genitalia, External Approach, No Device, No Qualifier | Complicated scrotal/perineal abscess (Urology) |
0H9GXZZ | Drainage, Skin, Face, External Approach, No Device, No Qualifier | Complicated facial abscess |
PCS Character Analysis — 0H95XZZ
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical |
| 2 | Body System | H | Skin and Breast |
| 3 | Root Operation | 9 | Drainage (taking or letting out fluids and/or gases from a body part) |
| 4 | Body Part | 5 | Skin, Neck |
| 5 | Approach | X | External |
| 6 | Device | Z | No Device |
| 7 | Qualifier | Z | No Qualifier |
PCS Root Operation: Drainage (9) vs. Excision (B)
- Use Drainage (9) when the definitive action is I&D without tissue removal.
- Use Excision (B) when HS disease requires wide excision of affected skin and subcutaneous tissue — a fundamentally different operation coded with the Medical and Surgical root operation Excision.
- When multiple separate anatomic sites are drained in the same inpatient episode, assign separate PCS codes for each body part — PCS has no equivalent to the “multiple” descriptor in 10061.
📝 Coding Examples
Example 1 — Office: Complicated HS Abscess, Axilla
Clinical Scenario: A 41-year-old female with known Hurley Stage II hidradenitis suppurativa presents with three confluent, fluctuant nodules in her right axilla. The operative note reads: “Three contiguous abscess cavities identified in the right axilla; separate incisions made over each; extensive loculations broken down bluntly; copious purulent material expressed from all three cavities; through-and-through iodoform packing placed.” A separately documented E/M is noted for medication management.
| Field | Code | Rationale |
|---|---|---|
| E/M | 99213-25 | Separately identifiable E/M for medication management (doxycycline adjustment); modifier -25 on E/M, not procedure |
| CPT | 10061 | Multiple confluent abscesses with multiple incisions and extensive loculation breakdown explicitly documented |
| PDx | L73.2 | Hidradenitis suppurativa — most specific code for this diagnosis |
Note
Example 2 — Outpatient Hospital: Complicated Neck Abscess (OTO)
Clinical Scenario: A 55-year-old male with poorly controlled type 2 diabetes presents to the outpatient surgery center for drainage of a 6 cm complicated right neck abscess. The procedure note documents two counter-incisions, extensive blunt dissection through multiple fibrous loculations, placement of a Penrose drain, and copious saline irrigation. No E/M is separately documented.
| Field | Code | Rationale |
|---|---|---|
| CPT | 10061 | Complicated single abscess; two counter-incisions; extensive loculation breakdown; Penrose drain placement — all documented |
| PDx | L02.211 | Cutaneous abscess of neck — site-specific code; right side is not further differentiated in ICD-10-CM at this category |
| SDx | E11.9 | Type 2 diabetes mellitus without complications — clinically significant comorbidity affecting wound healing and antibiotic selection |
Warning
Example 3 — Office: Multiple Separate Abscesses, MRSA Positive
Clinical Scenario: A 38-year-old male presents for I&D of two separate, non-contiguous furuncles — one on the posterior neck and one on the right buttock. Each is drained with a separate incision. Prior cultures confirmed MRSA. The procedure note explicitly states: “Two separate abscesses at distinct sites; each incised and drained separately; packed individually.”
| Field | Code | Rationale |
|---|---|---|
| CPT | 10061 | Multiple separate abscesses treated in same session — by definition, this is the correct code; do not bill 10060 × 2 |
| PDx | L02.211 | Cutaneous abscess of neck — primary site listed first per clinical determination |
| SDx | L02.91 | Cutaneous abscess, unspecified — buttock is not separately classified; assign as secondary site |
| SDx | B95.62 | MRSA as causative organism — report as additional code; this is a CC under MS-DRG logic and affects medical necessity documentation |
Global period reminder:
The 10-day global period begins on the procedure date. All follow-up packing changes and wound checks for both sites are bundled. If the patient develops a third, new abscess at a third site within the 10-day window, report with modifier -79 (Unrelated Procedure During Postoperative Period) and ensure the new abscess site is clearly distinct in the documentation.
⚠️ Common Coding Pitfalls
- Upcoding 10060 to 10061 without documented complexity: Billing 10061 when the operative note describes only a single incision with simple drainage is a classic upcode pattern flagged by RAC and MAC audits. The documentation must explicitly support “complicated or multiple” — operative complexity must be evident from the note, not inferred.
- Billing 10060 + 10061 together for the same session: These two codes are mutually exclusive for the same encounter. 10061 captures the entire session when any component is complicated or when multiple abscesses are treated — do not stack them.
- Omitting organism codes when cultures are documented: When MRSA or another specific organism is identified, the corresponding additional diagnosis code (e.g., B95.62) must be reported. These codes affect CC/MCC status in the inpatient setting and support medical necessity in outpatient/payer review.
- Failing to document “complicated” with specificity-supporting language: Vague operative notes (e.g., “large abscess, drained”) do not support 10061. Train surgeons to use terms like “multiple cavities,” “counter-incisions,” “extensive loculations,” or “multiple separate lesions” to anchor the code selection.
- Missing the 10-day global window for wound checks: Identical to 10060 — packing changes and wound checks are bundled. Staff must be trained to flag procedure dates and avoid billing separate E/M codes for routine post-I&D follow-up within the window.
- Defaulting to L02.91 when site is documented: The operative note for a complicated abscess will almost always identify the anatomic location. Always assign the most specific site code available before defaulting to unspecified.
