Answer:
There are several possibilities for coding the unknown skin rash. More information from the NPP will help to identify the ICD-9 code to append to your E/M service code. When deciding the most appropriate code, consider these options:You may consider selections from category 692.x (Contact dermatitis and other eczema). This category includes "Dermatitis: Not Otherwise Specified (NOS), contact, occupational, venenata"; and "Eczema (acute or chronic): NOS, allergic, erythematous, occupational." You must also use a fourth or fifth digit with this category, which excludes certain types of dermatitis.
