ICD-10 Code L97: Non-pressure chronic ulcer of lower limb, not elsewhere classified

L97 is an ICD-10 diagnosis entry used to group records related to Non-pressure chronic ulcer of lower limb, not elsewhere classified. You may see this entry in coding references, medical records, or claims workflows when a broader diagnosis category is being reviewed before a more specific code is chosen.

This code sits within the broader ICD-10 area for Diseases of the skin and subcutaneous tissue (L00-L99).

What is this code?

ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Diseases of the skin and subcutaneous tissue (L00-L99).

When is it used?

  • May be used when a clinician documents non-pressure chronic ulcer of lower limb, not elsewhere classified in a patient's medical record.
  • May appear in hospital records, claims, referrals, and clinical documentation.
  • This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.

What it does not mean

  • A code alone does not explain severity, treatment plan, or outcome.
  • A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
  • This entry may represent a broader category rather than the most specific billable code.
