2025 ICD-10-CM Procedure Code 01PY4MZ

Removal of Neurostimulator Lead from Peripheral Nerve, Percutaneous Endoscopic Approach

ICD-10-PCS Code:
01PY4MZ
ICD-10-PCS Code for:
Removal of Neuro Lead from Periph Nrv, Perc Endo Approach
Is Billable?
Yes - Valid for Submission
Code Navigator:

01PY4MZ is a billable procedure code used to specify the performance of removal of neurostimulator lead from peripheral nerve, percutaneous endoscopic approach. The code is valid for the year 2025 for the submission of HIPAA-covered transactions. The procedure code involves taking out or off a device from a body part. Procedure code explanation: if a device is taken out and a similar device put in without cutting or puncturing the skin or mucous membrane, the procedure is coded to the root operation change. otherwise, the procedure for taking out a device is coded to the root operation removal drainage tube removal, cardiac pacemaker removal

01PY4MZ PCS Table

In an PCS table each code is represented by up seven alphanumeric characters, with each character in the table respresenting different aspects of the procedure. In the table provided below, each row represents an individual character and includes information about the character's position, designation, label, and procedure notes. For this PCS table the procedure code is in the medical and surgical section and is part of the peripheral nervous system body system, classified under removal operation. The applicable bodypart for this procedure code is peripheral nerve.

Position Designation Character Label Procedures Notes
1 Section 0 Medical and Surgical
2 Body System 1 Peripheral Nervous System
3 Operation P Removal

Involves:
Taking out or off a device from a body part

Explanation:
If a device is taken out and a similar device put in without cutting or puncturing the skin or mucous membrane, the procedure is coded to the root operation CHANGE. Otherwise, the procedure for taking out a device is coded to the root operation REMOVAL

Includes:
  • Drainage tube removal, cardiac pacemaker removal
4 BodyPart Y Peripheral Nerve  
5 Approach 4 Percutaneous Endoscopic

Involves:
Entry, by puncture or minor incision, of instrumentation through the skin or mucous membrane and any other body layers necessary to reach and visualize the site of the procedure
6 Device M Neurostimulator Lead
7 Qualifier Z No Qualifier

Explanation:
The value Z is used for the seventh character to indicate that a specific qualifier does not apply to the procedure.

What is ICD-10-PCS?

The ICD-10 Procedure Coding System (ICD-10-PCS) is a catalog of procedural codes used by medical professionals for hospital inpatient healthcare settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates. The 2025 ICD-10-PCS codes are to be used for discharges occurring from October 1, 2024 through September 30, 2025.

Each ICD-10-PCS code has a structure of seven alphanumeric characters and contains no decimals. The first character defines the major "section". Depending on the "section" the second through seventh characters mean different things.
