CPT 01992: Anesthesia for Nerve Blocks and Injections, Prone or Flat Position
CPT code 01992 represents anesthesia services for diagnostic or therapeutic nerve blocks and injections, performed when the procedure itself is conducted by a different physician or qualified health care professional. This code is specifically used when the patient is in a prone or lying flat position, and is most commonly billed in outpatient hospital settings. Nationally, this code is significant for ensuring proper reimbursement and documentation of anesthesia care in pain management and interventional procedures.
Major payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare.

This article is designed to inform stakeholders about the clinical and billing implications of CPT code 01992, offering a comprehensive overview of its role in outpatient anesthesia care and its importance in pain management protocols.
CPT Code Overview
CPT code 01992 is used to report anesthesia services provided for diagnostic or therapeutic nerve blocks and injections, specifically when the block or injection is performed by a different physician or qualified health care professional. This code applies when the patient is positioned prone or lying flat during the procedure. The typical site of service for CPT code 01992 is an outpatient hospital setting, designated as Place of Service 22. This code is essential for accurately documenting and billing anesthesia care in scenarios where nerve block or injection procedures require specialized patient positioning and are performed collaboratively by multiple providers.
Clinical & Coding Specifications
Clinical Context
A patient with chronic low back pain, cervicalgia, or fibromyalgia presents to an outpatient hospital for a diagnostic or therapeutic nerve block or injection. The procedure is performed by a pain management specialist or other qualified provider. An anesthesia provider, such as an anesthesiologist or anesthesiologist assistant, administers anesthesia while the patient is positioned prone or lying flat. The anesthesia ensures patient comfort and safety during the nerve block or injection, which is performed by a different physician or qualified health care professional. Typical workflow involves pre-procedure assessment, anesthesia induction, monitoring during the procedure, and post-procedure recovery.
Coding Specifications

Related Diagnoses
-
M54.5- Low back pain- Relevant for patients undergoing nerve block or injection to manage chronic or acute low back pain.
-
G89.29- Other chronic pain- Indicates chronic pain conditions that may require nerve block or injection for relief.
-
M54.2- Cervicalgia- Used for patients with neck pain, often treated with nerve block or injection procedures.
-
M79.7- Fibromyalgia- Represents widespread pain syndromes, where nerve block or injection may be part of the pain management strategy.
-
G89.18- Other acute postprocedural pain- Applied when the patient experiences acute pain following a prior procedure, necessitating further pain management interventions such as nerve blocks or injections.
Each diagnosis code is clinically relevant as it identifies patients who may benefit from nerve block or injection procedures requiring anesthesia as described by 01992.
Related CPT Codes
64450: Injection, anesthetic agent; other peripheral nerve or branch. Used for peripheral nerve blocks, often performed in conjunction with anesthesia.64483: Injection(s), anesthetic agent and/or steroid, transforaminal epidural; lumbar or sacral, single level. Commonly used for lumbar or sacral epidural injections, which may require anesthesia as described by01992.62322: Injection(s), of diagnostic or therapeutic substance(s) (e.g., anesthetic, antispasmodic, opioid, steroid), not including neurolytic substances, including needle or catheter placement, interlaminar epidural or subarachnoid; cervical or thoracic. Used for cervical or thoracic epidural injections, often requiring anesthesia support.01991: Anesthesia for diagnostic or therapeutic nerve blocks and injections (when block or injection is performed by a different provider); supine position. Similar to01992, but used when the patient is in a supine position rather than prone or lying flat.
These codes are related as they represent either the injection procedures themselves or anesthesia services for nerve block procedures. 01992 is used specifically for anesthesia when the patient is prone or lying flat, while 01991 is used for supine positioning. Injection codes (64450, 64483, 62322) are commonly paired with anesthesia codes when performed by different providers.
