About L44.9

L44.9 is the ICD-10-CM diagnosis code for papulosquamous disorder, unspecified. It belongs to category L44 (other papulosquamous disorders), block L40-L45 (papulosquamous disorders) and chapter 12 (diseases of the skin and subcutaneous tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within L44, choose L44.9 (Papulosquamous disorder, unspecified) only when documentation doesn't support a more specific option: pityriasis rubra pilaris (L44.0), lichen nitidus (L44.1), lichen striatus (L44.2), lichen ruber moniliformis (L44.3), infantile papular acrodermatitis [Gianotti-Crosti] (L44.4) and other specified papulosquamous disorders (L44.8).

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 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 709.8 (other specified disorders of skin).
