Summary & Overview
Other skin changes: ICD-10-CM Diagnosis Code Group Overview
International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes under the group ICD-10-CM R23 describe nonspecific skin and subcutaneous tissue changes such as discoloration, pallor, cyanosis, and other abnormal surface findings. Accurate ICD-10-CM coding for these signs is important for correct claim adjudication and appropriate reimbursement.
Other skin changes Overview
The diagnoses in this group represent nonspecific skin and subcutaneous tissue findings such as discoloration, pallor, cyanosis, and other surface changes that do not fit more specific dermatologic categories. They target signs observed on the integumentary system that may reflect local skin conditions or systemic disease. Accurate coding ensures clinical records reflect the presenting skin signs and supports correct claim processing and payment determination under ICD-10-CM.
Typical Clinical Scenarios
- An elderly patient presents to urgent care with sudden-onset generalized yellowing of the skin noticed over the past 48 hours, without scleral icterus, and the clinician documents diffuse skin discoloration without a definitive dermatologic lesion; workup for systemic causes is initiated and a symptom code for skin color change is assigned. Typical codes:
R231 - A middle-aged patient in a dermatology clinic has persistent localized skin darkening over the anterior lower leg following prior inflammation and hyperpigmented patching that has been stable for months; the visit addresses chronic postinflammatory pigmentary change and a non-specific hyperpigmentation code is used. Typical codes:
R233 - A patient in the emergency department after heat exposure has flank and torso areas of transient redness and mottled skin without signs of infection, dehydration, or systemic illness; the clinician documents generalized skin redness or erythema as a presenting sign and assigns an appropriate sign code. Typical codes:
R230,R239
