684 is a legacy ICD-9-CM diagnosis code for impetigo. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. Under the CMS General Equivalence Mappings, it maps to 2 ICD-10-CM candidates: L01.00 and L01.03.

Information for Patients

Impetigo

Impetigo is a skin infection caused by bacteria. It is usually caused by staphylococcal (staph) bacteria, but it can also be caused by streptococcal (strep) bacteria. It is most common in children between the ages of two and six. It usually starts when bacteria get into a break in the skin, such as a cut, scratch, or insect bite.

Questions About 684

Is 684 (impetigo) still a valid code?

No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes, such as L01.00 and L01.03.

What is the ICD-10 replacement for 684?

The General Equivalence Mappings list 2 ICD-10-CM candidates for this code: L01.00 (Impetigo, unspecified) and L01.03 (Bullous impetigo). Each match is approximate, so the right choice depends on what the documentation supports.

What did 684 mean?

In the final ICD-9-CM release, this code described impetigo. It sat in block 684 Impetigo under Diseases of the skin and subcutaneous tissue (680–709).

Why does 684 map to more than one ICD-10 code?

ICD-10-CM is more specific than ICD-9-CM. The detail packed into this single legacy code was split across L01.00 and L01.03, so the General Equivalence Mappings list every candidate rather than forcing one. The correct target is the one the documentation supports.
