ICD-10 Code Families
Complete code families applicable to L90.5
When to use each related code
| Description | When to use |
|---|---|
| Depressed or raised scars from acne. | Use for visible scarring after acne lesions resolve. Consider scar type (atrophic, hypertrophic, keloid). |
| Enlarged, raised scars beyond initial injury. | Use for scars extending beyond the original acne lesion, firm and raised. Often red or pink. |
| Excessive scar tissue growth, raised and firm. | Use for very large, raised scars growing beyond original acne area. May be itchy or painful. |
Best-practice checklist
- ✓Document scar type (atrophic, hypertrophic, keloid)
- ✓Specify scar location and size (mm)
- ✓Note scar morphology (ice pick, boxcar, rolling)
- ✓Record any associated symptoms (pain, itching)
- ✓Assess pigmentation changes (hyperpigmentation, hypopigmentation)
Common pitfalls to avoid
Coding acne scarring without specifying the type (e.g., atrophic, hypertrophic, keloid) can lead to rejected claims or inaccurate reimbursement.
Lack of documentation specifying the severity (mild, moderate, severe) of acne scarring may impact medical necessity reviews and coding accuracy.
Using varying terms like "post-acne scarring" or "acne scar" without clear linkage to "acne scarring" can create coding inconsistencies and audit issues.
Best-practice tips
- 01Minimize scarring: Early acne treatment.
- 02ICD-10: L90.5; Document scar type, morphology.
- 03Reduce inflammation: Avoid picking, squeezing.
- 04Topical retinoids, chemical peels: Improve texture.
- 05Fractional lasers, microneedling: Consult dermatologist.
Step-by-step checklist
- 1
Confirm acne scar type (ice pick, boxcar, rolling) matches documentation and ICD-10 (L70.0).
- 2
Verify scar location and size are clearly documented for accurate coding and treatment.
- 3
Assess for psychological impact of scarring and document patient reported outcomes (PROs).
- 4
Review prior treatments and their effectiveness for informed decision-making.
Ready-to-paste narrative
Patient presents with acne scarring, consistent with post-acne scarring, characterized by atrophic acne scars on the [location - e.g., face, back, chest]. The patient reports a history of acne vulgaris, with onset at [age of onset]. The scarring presents as [scar type - e.g., ice pick, boxcar, rolling] and is [severity - e.g., mild, moderate, severe] in appearance. Skin examination reveals [detailed description of scar characteristics - e.g., dyspigmentation, textural changes, indentation]. Differential diagnoses considered include other types of scarring, such as varicella scarring and traumatic scarring. The patient's Fitzpatrick skin type is [skin type]. Current treatment plan includes [treatment options - e.g., topical retinoids, chemical peels, microneedling, laser resurfacing, dermal fillers] to address the atrophic scarring and improve skin texture and appearance. Patient education provided on scar management, sun protection, and realistic expectations for treatment outcomes. Follow-up scheduled in [duration - e.g., 4 weeks] to assess treatment response and adjust the plan as needed. ICD-10 code L70.0 (Acne keloid) or L90.5 (Scar conditions and fibrosis of skin) may be considered depending on the specific scar type. CPT codes for procedures performed, such as microneedling or laser resurfacing, will be documented separately.
Common questions and answers
What are the most effective treatment strategies for differentiating and managing atrophic acne scars in Fitzpatrick skin types IV-VI?+
Atrophic acne scars, including ice pick, boxcar, and rolling scars, present unique challenges in Fitzpatrick skin types IV-VI due to the increased risk of post-inflammatory hyperpigmentation (PIH). Effective management requires a tailored approach considering both scar subtype and skin tone. For ice pick scars, TCA CROSS, punch excision, or radiofrequency microneedling can be effective. Boxcar scars often respond well to subcision, fillers, or laser resurfacing. Rolling scars may benefit from subcision combined with fillers or laser treatments. When treating skin of color, it's crucial to use lower energy settings for lasers and chemical peels to minimize PIH risk. Prioritizing treatments that stimulate collagen remodeling, such as microneedling with radiofrequency, may also be beneficial. Explore how combination therapies can enhance outcomes and consider implementing preventative measures like early acne treatment to minimize scarring risk in these skin types. Learn more about managing PIH with topical agents like hydroquinone, retinoids, and corticosteroids after procedural treatments.
How can I accurately assess and classify different acne scar types to determine the optimal treatment approach for my patients?+
Accurate acne scar classification is fundamental for selecting the most effective treatment strategy. Begin by visually inspecting the scars under good lighting, possibly with magnification. Atrophic scars are categorized as ice pick, boxcar, or rolling based on their morphology. Ice pick scars are narrow, deep, and sharply defined. Boxcar scars are wider, with well-defined vertical edges, resembling a 'boxcar.' Rolling scars are broader, shallower depressions with sloping edges that give the skin a wave-like appearance. Hypertrophic scars, conversely, are raised and firm due to excess collagen. Keloid scars extend beyond the original wound boundaries. Proper assessment involves not only identifying the scar type but also considering skin type, patient preferences, and potential complications. Consider implementing standardized photographic documentation to track treatment progress. Explore how dermatoscopy can aid in detailed scar assessment and differentiation.
Beyond lasers and fillers, what emerging or non-invasive treatment modalities show promise for acne scar reduction and how can I integrate them into my practice?+
While lasers and fillers remain valuable for acne scar treatment, emerging non-invasive modalities offer promising results and expand treatment options. Microneedling with radiofrequency, for instance, combines microneedles with radiofrequency energy to stimulate collagen and elastin production, improving both atrophic and hypertrophic scars. Platelet-rich plasma (PRP) therapy, when combined with microneedling or other procedures, can enhance collagen synthesis and tissue regeneration. Topical treatments like retinoids, growth factors, and silicone gels can improve scar appearance and reduce redness. Furthermore, fractional radiofrequency and ultrasound technologies offer skin tightening and scar remodeling with minimal downtime. Explore how incorporating these modalities can cater to a broader patient base and address specific scar types effectively.
