Summary & Overview
ICD-10-PCS Code For Skin, Arm: Procedure Code Group Overview
The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group DHY4 includes procedures performed to deliver other radiation treatments to the skin of the arm. These ICD-10-PCS codes are used for inpatient documentation when a patient receives non-standard or other specified radiation therapy directed at arm skin lesions or conditions as part of their hospital stay. Accurate coding within the ICD-10-PCS DHY4 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Typical Clinical Scenarios
- An elderly patient with extensive nonmelanoma skin cancer (squamous cell carcinoma) of the forearm has undergone wide local excision but requires inpatient radiotherapy for residual superficial disease because of positive margins and proximity to critical structures; inpatient delivery of localized skin/arm radiation is chosen for close monitoring of wound healing and pain control. Typical codes:
DHY47ZZ,DHY48ZZ - A middle-aged patient presents with an acute, uncontrolled flare of severe radiation dermatitis from prior outpatient treatment for breast/chest wall recurrence involving the ipsilateral arm skin, leading to infected ulceration and systemic symptoms; inpatient administration of targeted radiation to the affected arm skin is performed as part of palliative control when other measures have failed. Typical codes:
DHY4FZZ,DHY48ZZ - A younger adult with a recurrent keloid and hypertrophic scarring of the upper arm after prior surgical revisions, electively admitted for planned inpatient specialized radiation therapy to the arm skin to reduce recurrence risk following definitive excision under anesthesia; the inpatient setting allows coordination of surgery and immediate postoperative radiation.
