Z41.1Encounter for cosmetic surgery

Z41.1 is the ICD-10-CM diagnosis code for encounter for cosmetic surgery. It belongs to category Z41 (encounter for procedures for purposes other than remedying health state), block Z40-Z53 (Encounters for other specific health care) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Z41 (encounter for procedures for purposes other than remedying health state), Z41.1 is specifically for encounter for cosmetic surgery. Related codes cover routine and ritual male circumcision (Z41.2), ear piercing (Z41.3), other procedures for purposes other than remedying health state (Z41.8) and procedure for purposes other than remedying health state, unspecified (Z41.9).

Don't report Z41.1 together with the conditions in its Excludes1 note: encounter for plastic and reconstructive surgery following medical procedure or healed injury (Z42.-) and encounter for post-mastectomy breast implantation (Z42.1).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as V50.1 (other plastic surgery for unacceptable cosmetic appearance).
