For lip augmentation using collagen injections, which codes would be reported for the preoperative diagnosis and the procedure?

• A. Z41.1, 11950
• B. Z41.0, 11951
• C. Z41.2, 11952
• D. Z41.1, 11951

Answer: (D)

The scenario tests pairing an encounter diagnosis with the exact procedure code for a cosmetic lip augmentation with collagen. For cosmetic procedures, the diagnosis is an encounter code rather than a disease code. Z41.1, “Encounter for cosmetic surgery,” best fits a lip augmentation performed purely for cosmetic reasons. The procedure code should match the specific injectable filler used; 11951 is the CPT code that represents injection of a dermal filler (collagen) for lip augmentation. The other CPT options would cover different materials or different levels of injection, which aren’t appropriate for collagen lip augmentation, and the other ICD-10-CM options don’t describe the cosmetic encounter as precisely. So the paired and correct choice is Z41.1 with 11951.
