ICD-10-PCS Code For Integumentary System - Head And Neck: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group F01D includes procedures performed to assess motor and nerve function of integumentary structures in the head and neck. These ICD-10-PCS codes are used for inpatient documentation when clinicians perform motor or nerve function assessment testing of the skin and superficial tissues of the head and neck to evaluate neurologic integrity or functional deficits. Accurate coding within the ICD-10-PCS F01D group is essential for proper inpatient reimbursement, as it captures the procedure performed and supports clinical documentation accuracy.

Integumentary System - Head And Neck Motor And/or Nerve Function Assessment Procedure Overview

This code group includes procedures that assess motor and nerve function of the integumentary structures in the head and neck. These assessments evaluate nerve or motor responses, sensory integrity, and related skin and superficial tissue function in the head and neck region. Accurate coding of these assessments matters for inpatient reimbursement because it documents the diagnostic and functional testing performed and supports correct case mix assignment and payment.

Typical Clinical Scenarios

A 68-year-old stroke patient admitted with new right facial droop and decreased sensation over the right cheek and perioral skin. During the inpatient rehabilitation stay, clinicians perform bedside assessments of facial skin motor response and sensory integrity to document residual nerve function and guide therapy intensity. A basic assessment without specialized equipment is performed to evaluate muscle performance and cutaneous sensation of the head and neck integumentary structures. Typical codes: F01D0ZZ, F01D6ZZ
A 45-year-old patient admitted for planned postoperative rehabilitation after facial reconstructive surgery following tumor resection. The therapy team conducts systematic muscle performance testing of perioral and perinasal skin and superficial tissues using an assistive/supportive device to measure facial muscle activation and to protect delicate tissues during testing. Documentation requires coding the muscle performance assessment that utilized supportive equipment. Typical codes: F01D0FZ
A 52-year-old patient with chronic peripheral facial neuropathy presents for inpatient evaluation after worsening sensory deficits and skin breakdown around the lower face. Clinicians perform a detailed sensory integrity assessment using specialized external supportive/protective equipment to map areas of decreased sensation and to prevent further integumentary injury while planning wound care and neurorehabilitation. The procedure documents sensory processing and integumentary integrity assessment using other equipment. Typical codes: F01D1ZZ, F01D6YZ
