CPT 01990: Anesthesiology Physiologic Support for Organ Procurement
CPT code 01990 denotes anesthesiology services providing physiological support to a brain-dead patient during organ procurement. This code captures specialized intraoperative management aimed at preserving donor organ function during recovery procedures, and it is used in hospital operating rooms or dedicated procurement suites. The code matters nationally because organ transplantation involves complex perioperative care, cross-disciplinary coordination, and specific billing pathways distinct from routine anesthesia services.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the code, common settings where the service is delivered, and links to related anesthesia and procedural codes for reference. The publication summarizes payer coverage considerations and coding relationships that affect billing for organ procurement anesthesia, and highlights areas where policy clarification or coding guidance is commonly sought. This resource is intended for billing professionals, anesthesia providers, hospital revenue cycle staff, and compliance officers who need a clear, national-level description of the service represented by CPT code 01990.

Billing Code Overview
CPT code 01990 describes physiological support provided by an anesthesiology provider to a brain-dead patient during organ procurement. The service involves management of cardiopulmonary and related physiological functions to maintain organ viability while organs are surgically recovered.
Service type: Anesthesiology – organ procurement physiological support
Typical site of service: Hospital operating room or organ procurement surgical suite
Clinical & Coding Specifications
Clinical Context
A typical patient is a legally declared brain-dead adult in an operating room or linked suite where organ procurement is planned for transplantation. The patient may be supported with mechanical ventilation and vasoactive infusions to maintain perfusion of transplantable organs. The anesthesiology provider is present to deliver physiological support during the procurement procedure, which includes hemodynamic optimization, ventilatory management, fluid balance, and coordination with the surgical and transplant teams. Common workflow steps: pre-procurement briefing with transplant surgeons and organ procurement organization; confirmation of brain death documentation (G93.82) and consent; review of relevant comorbidities including prior transplant status (Z94.0) or device dependence (Z99.89); induction and maintenance of physiologic support measures (vasopressors, inotropes, ventilator settings, temperature management); intraoperative monitoring (arterial line, central access as indicated); rapid coordination for organ-specific procurement (kidneys, liver, heart, lungs) with intermittent adjustments to maintain organ perfusion and oxygenation; handoff to recovery/transplant team and documentation of physiological parameters and medications titrated during the procurement period. Typical site of service is the operating room or an authorized organ procurement suite within a hospital. Typical service type is intraoperative physiological support/anesthesia care specifically directed to a brain-dead donor during organ procurement.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
AA | Anesthesia services performed personally by anesthesiologist | Use when the anesthesiologist personally performs the physiological support for the organ procurement. |
AD | Medical supervision by a physician; more than four concurrent anesthesia procedures | Use when the physician supervises multiple concurrent anesthetics including organ procurement and provides documented medical direction. |
QK | Medical direction of two, three, or four concurrent anesthesia procedures involving qualified individuals | Use when the anesthesiologist directs qualified individuals (e.g., CRNA) for this procurement and is present for portions as defined by CMS. |
QS | Monitored anesthesia care service | Use only if the service is billed as monitored anesthesia care rather than general anesthesia; rarely applicable for full donor physiologic support. |
62 | Two surgeons | Use when two surgeons share primary responsibility for the operative procurement (reports by surgical team may require this modifier for surgical CPTs). |
78 | Unplanned return to the operating room following initial procedure for a related procedure during the postoperative period | Use if the donor requires re-entry for additional procurement actions directly related to the initial operation. |
52 | Reduced services | Use if physiologic support is partially provided or abbreviated compared to full documented service (with clear documentation). |
53 | Discontinued procedure | Use if procurement is initiated but discontinued for documented clinical reasons before completion of intended support tasks. |
56 | Preoperative assessment only | Use if the anesthesiology provider only conducted a preoperative evaluation and did not provide intraoperative physiologic support. |
23 | Unusual anesthesia | Use when unusual anesthesia circumstances exist (e.g., organ procurement in non-standard environment) that increase complexity. |
22 | Increased procedural services | Use when significant additional work or complexity beyond typical physiological support is documented (must be supported by operative/anesthesia report). |
AA | (listed already) | (duplicate omitted) |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for anesthesia assist | Use when an assistant qualified by state law provides anesthesia-related monitoring/support under supervision during procurement. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Physicians who provide the physiologic support and anesthesia management for organ procurement. |
367500000X | Certified Registered Nurse Anesthetist | CRNAs who may deliver anesthesia and physiologic management for the donor under supervision or direction. |
207LA0401X | Anesthesiology Assistant | Anesthesiology assistants who participate under physician supervision in perioperative support during procurement. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
Z00.6 | Encounter for examination for normal comparison and control in clinical research program | May appear when donor evaluation occurs in contexts tied to research programs or standardized comparisons of organ procurement outcomes. |
Z99.89 | Dependence on other enabling machines and devices | Relevant when the donor requires continued mechanical ventilation or other life-sustaining devices during procurement. |
R99 | Ill-defined and unknown cause of mortality | May be used in documentation when cause of death is pending or not fully defined in the donor record during administrative processes. |
G93.82 | Brain death | Primary clinical diagnosis indicating legal brain death status of the donor, which is the clinical basis for organ procurement and use of 01990. |
Z94.0 | Kidney transplant status | Relevant for donors who are prior transplant recipients or when noting recipient/donor transplant status in records; appears in peri-procurement documentation when kidney transplant history is present. |
