L88: ICD10 Code for Pyoderma gangrenosum

L88 refers to Pyoderma gangrenosum, which includes a diverse set of skin and subcutaneous tissue disorders such as pigmentary changes, ulcerative lesions, connective tissue diseases, procedural complications, and keratinization issues. These often require multidisciplinary care and long-term monitoring.

Symptoms

• Skin discoloration – Found in vitiligo (L80), pigmentation disorders (L81), or lupus (L93)
• Thickening or hardening of skin – Seen in keratoderma (L86), calluses (L84), or hypertrophic skin (L91)
• Painful skin ulcers – Found in L88, L89, or chronic leg ulcers (L97)
• Scarring or skin atrophy – Occurs in L90 or procedural issues (L76)
• Visible plaques or nodules – Associated with granulomatous (L92) or autoimmune causes (L95)

Diagnosis

Diagnosis of Pyoderma gangrenosum includes patient history, skin examination, biopsy, dermoscopy, wound staging (e.g., pressure ulcers), and immunological tests when autoimmune conditions are suspected.

ICD10 Code Usage

ICD10 code L88 is used by dermatologists, wound care nurses, surgeons, rheumatologists, and internal medicine doctors. It helps document complex skin conditions for treatment, insurance claims, and chronic disease monitoring.

FAQs

Q1: What is ICD10 code L88?
A: It refers to Pyoderma gangrenosum, encompassing disorders such as skin thickening, ulceration, pigmentation loss, inflammation, or surgical complications.

Q2: What’s the difference between L89 and L97 ulcers?
A: L89 refers to pressure-related ulcers (bedsores), while L97 documents non-pressure chronic ulcers often due to vascular issues or diabetes.

Q3: Is vitiligo (L80) considered autoimmune?
A: Yes, it is thought to have an autoimmune component where melanocytes are destroyed by the immune system.

Q4: What does L76 include?
A: L76 includes infections, scarring, or necrosis occurring as complications of skin procedures like grafts, surgery, or cosmetic treatments.

Q5: Who treats these conditions?
A: Dermatologists, wound care teams, rheumatologists, plastic surgeons, and sometimes infectious disease specialists.

Conclusion

ICD10 code L88 enables precise diagnosis and ongoing documentation of Pyoderma gangrenosum, supporting specialized care, procedural tracking, and effective dermatologic or systemic disease management.
