ICD-10-PCS Code For Lymphatics, Lower Extremity: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group C75P includes procedures performed to introduce radioactive materials or use a nonimaging nuclear medicine probe in the lymphatics of the lower extremity. These ICD-10-PCS codes are used for inpatient documentation when nuclear medicine techniques are performed to map lymphatic drainage, identify sentinel lymph nodes, or measure lymphatic function in the lower extremity. Accurate coding within the ICD-10-PCS C75P group is essential for proper inpatient reimbursement, as it captures the specific diagnostic procedure performed and supports clinical documentation accuracy.

Lymphatics, Lower Extremity Nonimaging Nuclear Medicine Probe Procedure Overview

This procedure group includes introduction of radioactive materials or use of a nuclear medicine probe to evaluate lymphatic structures of the lower extremity within the lymphatic and hematologic system. Procedures involve detecting radioactive emissions or measuring absorption to map lymphatic drainage, identify sentinel nodes, or assess lymphatic function. Accurate ICD-10-PCS coding of these nonimaging nuclear medicine probe procedures is important for inpatient reimbursement because it captures the specific diagnostic technique and body system targeted.

When to Use

Use a code from this group when radioactive tracers are introduced or a nuclear medicine probe is used specifically to evaluate lymphatic structures in the lower extremity, such as sentinel node localization or lymphatic flow studies. Select the appropriate ICD-10-PCS code when the procedure is performed in the inpatient setting and the documentation specifies nonimaging nuclear medicine probe techniques for the lower extremity lymphatics.

C75P1ZZ	Nonimaging Nuclear Medicine Probe of Lower Extremity Lymphatics using Technetium 99m (Tc-99m)
C75PYZZ	Nonimaging Nuclear Medicine Probe of Lower Extremity Lymphatics using Other Radionuclide

Typical Clinical Scenarios

An inpatient admitted for staging of newly diagnosed lower extremity melanoma with clinically palpable groin lymphadenopathy. A nuclear medicine nonimaging probe is used intraoperatively after peritumoral injection of technetium-99m to localize sentinel lymph nodes draining the primary lesion prior to planned excision and node biopsy. The study guides the surgeon to the sentinel node(s) for removal and pathologic examination. Typical codes: C75P1ZZ
An elderly patient presents emergently with a rapidly expanding lower extremity soft tissue mass suspicious for recurrent melanoma after prior wide excision. During the inpatient workup, a nonimaging nuclear medicine probe examination is performed after injection of technetium-99m to map altered lymphatic drainage pathways and identify sentinel nodes affected by recurrence to direct urgent operative management. Typical codes: C75P1ZZ
A patient with chronic lymphedema of the lower extremity following prior pelvic lymph node dissection is admitted for evaluation of progressive swelling and recurrent infections. A nonimaging nuclear medicine probe study using an alternative radionuclide is performed to assess lymphatic drainage patterns and functional lymph flow to plan potential reconstructive or therapeutic interventions.
