• Correct Coding for Bilateral Dermatochalasis

    Question: When billing for an upper lid blepharoplasty, CPT code 15823, we have always used the -50 modifier to code as bilateral. There isn’t an ICD-10 code for dermatochalasis, bilateral. How do you recommend coding this procedure?

    Answer: Append both upper lid diagnosis codes on the line item for CPT code 15823.
