We have been getting denials for skin testing. The doctor and nurses are submitting diagnoses of diarrhea or stomach issues, the reason the patient is getting tested for food allergies, and they are being denied. Should we be coding with a screening ICD-10 code first with the GI issues secondary?

When you will bill skin testing with diarrhea or stomach issue, it will be denied for sure. Because according to medical coding perspective there is no relation between both. The payment will be cleared only when you use the supportive diagnosis codes with the CPT billed. In your case, there can be supportive diagnosis codes from the following: Z01.82- Encounter for allergy testing; R20, R21, R22, R23 series for Symptoms and Signs of Skin; T78.4 series- Other and unspecified allergy, K52.2 series for allergic diarrhea with Z91.01 series for food allergy. Check your documentation and reason for visit of the patient and select the diagnosis accordingly.
