Clinical Context
A middle-aged adult presents to an outpatient dermatology clinic with a suspicious pigmented skin lesion that has changed in size and color over several months. The clinician performs a diagnostic skin biopsy to obtain tissue for histopathologic evaluation to rule out melanoma or other malignancy. The workflow includes history and focused skin exam, informed consent, local anesthetic administration, sterile preparation, lesion excision or punch/shave biopsy, hemostasis, wound closure if needed, specimen labeling and submission to pathology, and post-procedure wound care instructions. Typical site of service is an outpatient clinic or ambulatory surgery center. Common scenarios include evaluation of a new or evolving nevus, ulcerated lesion, or non-healing lesion for which tissue diagnosis will guide further management.
Coding Specifications
| Modifier | Description | When to Use |
|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when a distinct E/M visit is performed and documented on the same day as the biopsy procedure. |
| 26 | Professional component | Use when reporting only the professional component of a diagnostic service provided to the patient (rare for biopsies; more applicable to imaging/pathology reporting).
| 52 | Reduced services | Use when the procedure is partially reduced or eliminated at the physician’s discretion.
| 57 | Decision for surgery | Use if the biopsy directly prompted a decision to perform surgery and an initial E/M resulted in the decision for the procedure (primary surgeon reporting on same day).
| 59 | Distinct procedural service | Use to indicate a separate and distinct biopsy when multiple procedures are performed at different sites or unrelated to each other.
| 76 | Repeat procedure or service by same physician | Use when the same biopsy procedure is repeated later the same day by the same physician.
| 77 | Repeat procedure by another physician | Use when another physician repeats the biopsy procedure the same day.
| 78 | Unplanned return to the operating/procedure room for a related procedure during the postoperative period | Use when the patient returns unexpectedly for additional operative management related to the biopsy.
| 80 | Assistant surgeon | Use when a second surgeon assists at the time of a complex excisional biopsy requiring assistance.
| RT | Right side | Use to indicate the procedure was performed on the right side of the body when side-specific reporting is required.
| Taxonomy Code | Specialty | Notes |
|---|
| 207Q00000X | Dermatology | Dermatologists commonly perform skin biopsies, both shave and excisional techniques. |
| 207L00000X | Dermatopathology | Dermatopathologists interpret biopsy specimens rather than perform the procedure; included for clinical workflow relevance.
| 208000000X | General Surgery | General surgeons perform excisional biopsies for deeper or suspicious lesions, often in ambulatory surgical settings.
| 363L00000X | Family Medicine | Primary care physicians frequently perform punch or shave biopsies during office visits.
| 207K00000X | Plastic Surgery | Plastic surgeons perform excisional biopsies and closures for cosmetically sensitive locations.

| ICD-10 Code | Description | Clinical Relevance |

D22.9 | Melanocytic nevus, unspecified | Common reason for biopsy when a nevus demonstrates suspicious change. |
| D23.9 | Other benign neoplasm of skin, unspecified | Used when a benign appearing lesion is biopsied to confirm diagnosis.
| C43.9 | Malignant melanoma of skin, unspecified | Biopsy diagnosis of a suspicious pigmented lesion may confirm melanoma; initial targeted lesion code.

| L08.9 | Cellulitis and abscess of unspecified site | Biopsy may be performed when infection is suspected to rule out neoplasm in atypical presentations.
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|
11102 | Tangential biopsy of skin (eg, shave, scoop, saucerize); single lesion | Performed when a superficial shave biopsy is appropriate for a lesion; may be used instead of an excisional biopsy for superficial lesions. |
| 11104 | Tangential biopsy of skin; each additional separate lesion (List separately in addition to code for primary procedure) | Billed when multiple separate shave biopsies are performed during the same encounter.
| 11100 | Biopsy of skin, subcutaneous tissue and/or mucous membrane (including simple closure), unless otherwise listed; single lesion | Used for punch or simple incisional biopsies where a small closure is performed.
| 11600 | Excision, malignant lesion including margins, trunk, arms or legs; excised diameter 0.5 cm or less | Applicable when biopsy yields malignancy and a definitive excision is performed subsequently; represents excisional management.
| 88305 | Level IV, surgical pathology, gross and microscopic examination | Represents the typical pathology interpretation code used for skin biopsy specimens submitted to the laboratory.
