ICD-10 Code Z48.02: Encounter for Removal of Sutures – Complete Coding & Billing Guide

ICD-10 code Z48.02 is a billable diagnosis code that designates an encounter specifically for the removal of sutures or staples following a surgical wound closure. It falls under the Z48.0 subcategory (“Encounter for attention to dressings, sutures and drains”) within Chapter 21 of the ICD-10-CM classification — Factors Influencing Health Status and Contact with Health Services. Understanding when this code applies, when it does not, and how it interacts with the global surgical package is essential for accurate revenue cycle compliance and clean claim submission.

What Does ICD-10 Code Z48.02 Mean?

Z48.02 classifies an outpatient or office encounter whose primary purpose is the removal of sutures or staples from a previously closed surgical wound. It is a valid, billable code effective since October 1, 2015, and remains active in the 2026 ICD-10-CM edition.

Key attributes of Z48.02:

• Valid and billable for fiscal year 2026 with no changes to description or validity
• Applies to encounters outside the global surgical period of the original procedure
• Used for both sutures and staples — the code covers either closure material
• Setting: Primarily outpatient/office, though applicable in other non-inpatient settings
• Parent category: Z48.0 (non-billable) — Z48.02 is the specific, billable child code to use

What Encounters Does Z48.02 Cover?

Z48.02 applies when a patient presents for the sole or primary purpose of having sutures or staples removed from a surgically closed wound. It is appropriate across a wide range of clinical contexts:

• Removal of skin sutures following elective surgery (e.g., cholecystectomy port sites, hernia repair, dermatologic excisions)
• Removal of staples after abdominal or orthopedic procedures
• Suture removal at a primary care office when the patient’s surgeon is in a different practice
• Follow-up encounters after procedures with a zero-day or expired global period where removal is now separately reportable

What Does Z48.02 Specifically Exclude?

The ICD-10-CM Tabular List includes important exclusion notes for the Z48 category that directly affect Z48.02 application:

• Excludes1 (never use together): Encounter for follow-up examination after completed treatment (Z08–Z09); encounter for aftercare following injury — code to the injury site with the appropriate 7th character for subsequent encounter
• Excludes2 (separate condition, may co-exist): Encounter for attention to artificial openings (Z43.-); encounter for fitting and adjustment of prosthetic and other devices (Z44–Z46)
• Excludes1 within Z48.0: Encounter for planned postprocedural wound closure (Z48.1) — if the visit purpose is to close a wound rather than remove sutures, Z48.1 is the correct code

When Is Z48.02 the Right Code to Use?

Correct code selection requires confirming several conditions before applying Z48.02. Use this numbered checklist before assigning the code:

1. Confirm the wound is surgical, not traumatic. Z48.02 is for post-surgical suture removal only. If sutures were placed to repair a traumatic laceration or injury, use the original injury code with 7th character “D” (subsequent encounter) instead.
2. Verify the global period has expired or is zero. According to CMS global surgical package rules, suture removal performed within the global period of the original procedure is bundled and not separately billable with Z48.02.
3. Confirm the primary purpose is suture/staple removal. If the visit also involves a new problem, significant evaluation, or separate identifiable E/M service, additional diagnosis codes and modifier -25 on the E/M code may be warranted.
4. Identify who placed the sutures. If the removing provider is different from the placing provider, HCPCS code S0630 may be appropriate for non-Medicare payers — but Z48.02 still serves as the diagnosis code in these scenarios.
5. Confirm no wound complication is the reason for the visit. If dehiscence, infection, or another postoperative complication is the driving reason for the encounter, a more specific complication code (e.g., T81.30XA–T81.33XA series) should be assigned instead of or alongside Z48.02.

How Does Z48.02 Differ From Z48.01 and Z48.03?

In practice, coders frequently encounter scenarios where both Z48.01 and Z48.02 may seem applicable — for example, when a provider changes a dressing and removes sutures in the same visit. In that case, Z48.02 takes priority as the more specific code describing the definitive procedural action of the encounter.

What Documentation Is Required to Support Z48.02?

Insufficient documentation is the leading cause of claim denial and audit exposure when using Z48.02. The clinical note must substantiate that the encounter’s purpose was suture or staple removal from a surgical (not traumatic) wound.

What Must the Provider Document in the Clinical Notes?

1. The original surgical procedure — identify the procedure that created the wound (e.g., “patient presents for suture removal following appendectomy performed on [date]”)
2. Wound status assessment — note the current appearance of the wound (e.g., “well-healed, no signs of erythema, dehiscence, or exudate”)
3. Type and number of sutures or staples removed — document the specific closure material (e.g., “12 staples removed from midline abdominal incision”)
4. Post-removal wound condition — describe the wound after removal (e.g., “wound edges well-approximated, no open areas noted”)
5. Date of original surgery — establishes context for global period determination
6. Confirmation that the procedure is outside the global period — this may be implicit from the date documentation but should be clear in the clinical record

Which Supporting Details Strengthen the Record?

• Notation of any wound care instructions provided to the patient
• Documentation of whether wound closure strips or other support was applied after suture removal
• Any follow-up instructions given, especially if healing was suboptimal
• Name and practice of the original surgeon if sutures were placed elsewhere (relevant for S0630 billing scenarios)

What Is the Documentation Standard for Inpatient vs. Outpatient Settings?

How Does Z48.02 Affect Medical Billing and Claims?

Understanding the billing implications of Z48.02 prevents denials rooted in global period conflicts and payer policy misapplication.

Key billing considerations:

• Global period verification is mandatory before billing Z48.02. The CMS National Physician Fee Schedule assigns 0, 10, or 90 global days to each CPT procedure code. Suture removal within any active global period is bundled — Z48.02 is not appropriate until the global period expires.
• Modifier -24 or -25 may be required when an E/M service is provided at the same visit as suture removal, depending on timing relative to the global period and payer rules.
• Medicare does not separately reimburse suture removal within the global period; for simple laceration repairs (CPT 12001–12018) with a zero global period, suture removal may be separately billable post-procedure.
• Non-Medicare commercial payers vary widely — always verify individual payer policies before billing Z48.02 with a separate E/M visit code.

What CPT or Procedure Codes Are Commonly Billed With Z48.02?

Are There Any Prior Authorization or Coverage Restrictions?

• Suture removal is generally considered a low-complexity service and does not typically require prior authorization
• Payers with narrow wound care Local Coverage Determinations (LCDs) may require supporting documentation confirming the visit is outside the surgical global package
• Some managed care organizations require that suture removal be performed by the original surgeon’s office during the global period — coordinate carefully when a different provider performs the removal

What Coding Errors Should You Avoid With Z48.02?

Auditors commonly flag Z48.02 in claims review when the code appears in contexts that conflict with global period rules or injury-aftercare guidelines. The following errors represent the most frequently cited compliance issues:

1. Billing Z48.02 within the global period. This is the single most common error. Always verify the global period of the original CPT code before assigning Z48.02.
2. Using Z48.02 for traumatic wound suture removal. If sutures close a laceration from an accident, fall, or other injury, the correct approach is the injury code (e.g., S01.81XD for subsequent encounter for open wound of scalp) — not Z48.02. The Excludes1 note under Z48 prohibits this combination.
3. Assigning Z48.02 without a wound status assessment in the note. Payers expect documentation confirming the wound was evaluated, not just that sutures were removed mechanically.
4. Using parent code Z48.0 instead of Z48.02. Z48.0 is a non-billable header code. Z48.02 is the required, billable child code. Submitting Z48.0 will result in rejection.
5. Failing to append modifier -25 to a separately identifiable E/M. When a provider performs a meaningful E/M service beyond the suture removal itself, modifier -25 on the E/M code is required to justify separate payment.

What Do Auditors Look for When Reviewing Claims With Z48.02?

• Date alignment: Is the service date after the global period end date for the original CPT?
• Wound type: Is the note clear that this is a surgical wound, not a traumatic wound?
• Documentation completeness: Does the note describe wound status, sutures removed, and post-removal condition?
• Code specificity: Was Z48.02 chosen over the non-billable Z48.0?
• Procedure-to-diagnosis match: Does the CPT code billed align logically with Z48.02?

How Does Z48.02 Relate to Other ICD-10 Codes?

Z48.02 operates within a tightly defined aftercare framework. Understanding its relationships to adjacent codes prevents both undercoding and overcoding.

What Is the Correct Code Sequencing When Z48.02 Appears With Other Diagnoses?

Per ICD-10-CM Official Coding Guidelines Section I.C.21, aftercare Z codes are generally sequenced as the principal or first-listed diagnosis when the encounter is for aftercare management:

1. Z48.02 as principal diagnosis — when the encounter’s sole purpose is suture removal
2. Additional Z48.8x code — if body-system-specific surgical aftercare is documented (e.g., Z48.812 for aftercare following orthopedic surgery)
3. Additional diagnosis codes — if a complication is identified at the visit (e.g., superficial wound infection), code the complication as an additional code
4. Do not sequence Z codes as principal for inpatient encounters when a more specific condition drives the admission — Z48.02 becomes an additional code in inpatient settings

Real-World Coding Scenario — How Z48.02 Is Applied in Practice

A 54-year-old established patient presents to her primary care physician 12 days after a laparoscopic appendectomy performed at an outpatient surgery center. The operative surgeon’s office is across town, and the patient has chosen to have her port-site sutures removed at her primary care office. The provider examines the three port sites, confirms the wounds are well-healed without erythema or discharge, and removes 6 interrupted nylon sutures. Wound closure strips are applied. The encounter is documented as a brief visit (Level 2 E/M).

Correct Code Application

• Z48.02 — Encounter for removal of sutures (primary diagnosis; post-surgical wound, outside global period for laparoscopic appendectomy — typically 10 or 90 days depending on CPT code billed)
• 99212 — Office visit, established patient (Level 2 E/M supported by documentation)
• S0630 — Suture removal by provider other than placing provider (if payer accepts; verify prior to billing)
• Modifier -25 appended to 99212 if payer requires to distinguish E/M from the suture removal service

Common Mistake in This Scenario

• Incorrect: Billing Z48.01 (encounter for change or removal of surgical wound dressing) because the provider also applied wound closure strips
• Why it fails: Z48.01 addresses dressing management; the primary action of this encounter was suture removal. Z48.02 is the more specific, appropriate code. If both actions were clinically distinct and documented separately, both codes could co-exist — but Z48.02 must reflect the primary encounter purpose.

Frequently Asked Questions About ICD-10 Code Z48.02

Is ICD-10 Code Z48.02 Valid for Use in 2026?

ICD-10 code Z48.02 is valid and billable for fiscal year 2026, with no changes to its description or validity status from prior years. Coders should verify annually against the CMS ICD-10-CM Official Coding Guidelines release, available through the CMS ICD-10 resources portal, to confirm no revisions have been applied.

Can Z48.02 Be Used for Staple Removal as Well as Suture Removal?

Yes — Z48.02 applies to the removal of both sutures (stitches) and surgical staples. The code description encompasses all non-absorbable closure materials removed in a postoperative follow-up encounter, making it the correct code whether nylon sutures, prolene sutures, or metallic staples are removed.

Should Z48.02 or an Injury Code Be Used When Sutures From a Laceration Are Removed?

An injury code with 7th character “D” (subsequent encounter) should be used instead of Z48.02 when sutures were placed to repair a traumatic wound. Per ICD-10-CM Official Coding Guidelines, aftercare Z codes such as Z48.02 are excluded for injury and trauma aftercare — the Excludes1 note under Z48 makes this a hard prohibition, not a judgment call.

What CPT Code Is Used With Z48.02 When Sutures Were Not Placed by the Billing Provider?

When suture removal is performed by a different provider than the one who placed the sutures, CPT add-on codes 15853 or 15854 (introduced in 2023) are used alongside the appropriate E/M code in office settings. HCPCS code S0630 may also be recognized by certain commercial payers in this scenario. Z48.02 remains the correct diagnosis code in all of these billing situations.

Does Billing Z48.02 Within the Global Period Trigger a Denial?

Billing Z48.02 for suture removal that occurs within the global period of the original surgical procedure will typically result in a claim denial or audit flag, because suture removal is bundled into the CMS global surgical package during that period. Before assigning Z48.02, always confirm the global period of the original CPT code using the CMS National Physician Fee Schedule or a verified coding tool.

What Is the Difference Between Z48.02 and Z48.1?

Z48.02 designates an encounter to remove sutures from a wound that has already been closed and is healing. Z48.1 (encounter for planned postprocedural wound closure) is used when the purpose of the visit is to close a wound that was intentionally left open — for example, a delayed primary closure after a contaminated abdominal procedure. These codes represent clinically opposite encounters and should never be confused.

Key Takeaways

• Z48.02 is billable in 2026 and covers removal of sutures and staples from post-surgical wounds
• Never use Z48.02 for traumatic wound aftercare — apply the injury code with 7th character “D” instead
• Global period compliance is the top priority — billing Z48.02 within an active global period is a leading cause of denial and audit exposure
• Documentation must confirm wound type, wound status, closure material removed, and post-removal condition
• Z48.02 vs. Z48.01 vs. Z48.03 — choose based on the specific action performed; these codes can co-exist if multiple services occur in one visit
• CPT add-on codes 15853/15854 (introduced 2023) are now the preferred billing vehicle for suture removal in non-facility settings alongside an E/M
• When a different provider performs the removal, S0630 may apply for commercial payers — verify before billing
