ANESTHESIA BACKGROUND
8-5 ANESTHESIA BACKGROUND The administration of anesthesia causes the loss of the ability to feel pain. Anesthesiology is essentially the practice of medicine dealing with: Management of procedures for rendering a patient insensible to pain during procedures The evaluation and management of life functions under the stress of anesthetic and surgical manipulations The clinical management of a patient unconscious from any cause The evaluation and management of problems with pain relief The management of problems in cardiac and respiratory resuscitation The application of specific methods of respiratory therapy The clinical management of various fluids, electrolytes, and metabolic disturbances
6
ANESTHESIA PROVIDERS Anesthesiologist Nurse anesthetist (CRNA)
8-6 ANESTHESIA PROVIDERS Anesthesiologist Physician specialized in providing anesthesia and pain management Nurse anesthetist (CRNA) Critical care nurses who have obtained additional training in providing anesthesia
7
TYPES OF ANESTHESIA General Regional Peripheral Nerve Block Local
8-7 TYPES OF ANESTHESIA General Patient is rendered unconscious Steps involved are: preparation, induction, maintenance, emergence, recovery Regional Numbs a part of the body without inducing unconscious 3 Types: Spinal, Epidural, Intravenous Regional Block Peripheral Nerve Block Injecting an anesthetic solution around a nerve Local Affects a small, specific area by injection, topical or spray Monitored Anesthesia Care (MAC) The administration of sedatives, hypnotics, analgesics and anesthetic drugs

ANESTHESIA CODING Codes are located in the Anesthesia Section of CPT
8-8 ANESTHESIA CODING Codes are located in the Anesthesia Section of CPT Also listed in the American Society of Anesthesiologists (ASA) Relative Value Guide Codes are grouped anatomically by body area Anesthesia section has 19 subsections Head Knee and Popliteal Area – 01444 Neck Lower Leg – 01522 Thorax Shoulder and Axilla – 01682 Intrathoracic – Upper Arm and Elbow – 01782 Spine – Forearm, Wrist & Hand – 01860 Upper Abdomen – Radiological Procedures – 01933 Lower Abdomen – Burn/Excisions – 01953 Peripeum – Obstetric – 01969 Pelvis – Other Procedures Upper Leg – 01274

ANESTHESIA SERVICES PACKAGE
8-9 ANESTHESIA SERVICES PACKAGE Anesthesia services have one code that pays for: General, regional, local anesthesia Interpretation of lab values Placement of IVs for fluid/medication administration Arterial line insertion for blood pressure monitoring The usual preoperative and postoperative visits The administration of fluids and/or blood The usual monitoring services Temperature, blood pressure, oximetry, ECG, capnography and mass spectrometry

11
OBSTETRICAL ANESTHESIA
8-11 OBSTETRICAL ANESTHESIA Two questions the coder should ask before assigning labor and delivery anesthesia codes Did the physician provide anesthesia for labor or only for delivery? Was the delivery vaginal or cesarean? Vaginal delivery codes are either or 01967 Cesarean delivery code is 01961
12
8-12 ANESTHESIA MODIFIERS All anesthesia codes are reported using the five-digit CPT Anesthesia section code plus the appropriate anesthesia modifier Three types of anesthesia modifiers Physical status modifiers CPT professional service modifiers HCPCS Level II modifiers

17
QUALIFYING CIRCUMSTANCES
8-17 QUALIFYING CIRCUMSTANCES Are used for difficult situations under which anesthesia is administered Are add-on codes (+), so they are listed along with the appropriate anesthesia code and never used alone If more than one qualifying circumstance code applies, more than one should be assigned Four Qualifying Circumstances Codes extreme age, under 1 year or over 70 years 99116 – utilization of total body hypothermia 99135 – utilization of controlled hypothermia 99140 – emergency condition
18
ASSIGNING ANESTHESIA CODES
8-18 ASSIGNING ANESTHESIA CODES 1. Refer to the main term in the index 2. Look for the anatomical site of the procedure performed 3. Locate the code in the Anesthesia section of CPT 4. Read and apply any notes that apply 5. Determine the payer—Medicare or non-Medicare 6. For Medicare, determine who provided the anesthesia (CRNA or MD), and assign appropriate modifier 7. Assign the applicable physical status modifiers (non-Medicare) 8. Determine the type of anesthesia that was administered 9. Assign codes for any qualifying circumstances 10. Assign any other applicable modifier
19
8-19 ANESTHESIA TIME Begins when the anesthesiologist begins to prepare the patient for the induction of anesthesia The anesthesia staff must continuously be present in order to calculate the time Anesthesia ends when the anesthesiologist is no longer in personal attendance Generally, anesthesia is calculated in 15 minute intervals.
20
ANESTHESIA CODING & BILLING RESOURCES
8-20 ANESTHESIA CODING & BILLING RESOURCES The American Society of Anesthesiologists website The American Society of Anesthesiologists book: The Relative Value Guide Medicare has a anesthesia webpage Commerical sources Decision Health’s Anesthesia & Pain Coder’s Pink Sheet and Anesthesia Answer Book The American Professional Academy of Coders (AAPC) Coding Edge The American Health Information Management Association's (AHIMA) Journal of the American Health Information Management Association

SURGERY CODING OVERVIEW
8-21 SURGERY CODING OVERVIEW The Surgery section is the largest section in CPT There are 16 subsections based on organ systems All surgery codes will begin with a 1, 2, 3, 4, 5 or 6 and are related to the subsection they are located in Most surgical subsections are divided by anatomical sites or organs within each body system Each anatomical site is then divided further by surgical method
22
SURGERY SUBSECTIONS Integumentary System 10021 - 19499
8-22 SURGERY SUBSECTIONS Integumentary System Musculoskeletal System Respiratory System Cardiovascular System Hemic and Lymphatic Systems Mediastinum and Diaphragm Digestive System Urinary System Male Genital System Intersex Surgery Female Genital System Maternity Care and Delivery Endocrine System Nervous System Eye and Ocular Adnexa Auditory System

SURGICAL METHODS WITHIN A SUBSECTION
8-23 SURGICAL METHODS WITHIN A SUBSECTION Incision and Drainage Biopsy Excision Introduction or Removal Repair Destruction Endoscopy/Laparoscopy Other Procedures
24
8-24 SURGERY GUIDELINES Be careful when assigning the add-on code for a microscope The term complicated appears in some code descriptions Some codes specify whether they are for one or both of an anatomical pair Add-on codes are never coded independently
25
SURGICAL PACKAGE AND THE GLOBAL PERIOD
8-25 SURGICAL PACKAGE AND THE GLOBAL PERIOD Time, effort and services for the surgical procedures are coded with a single package code Package includes: Local infiltration of anesthesia, the E/M visits either on the date of surgery or day before, immediate postoperative care, writing orders, evaluating the patient in the recovery room and typical, uncomplicated follow-up Global period is a defined time for routine preoperative and postoperative surgical care No days for simple procedures No days preoperative and ten days postoperative for minor surgery One day preoperative and ninety days postoperative for major surgery
26
BUNDLING Surgical packages are bundled
8-26 BUNDLING Surgical packages are bundled Bundled means that each package code contains all the related services Unbundling, or taking apart and reporting the services separately is a coding error and fraud
27
SERVICES NOT INCLUDED IN THE GLOBAL SURGERY PACKAGE
8-27 SERVICES NOT INCLUDED IN THE GLOBAL SURGERY PACKAGE The initial consultation or evaluation of the problem by the surgeon to determine the need for surgery. A modifier -57 would apply in this circumstance Diagnostic tests and procedures Distinctly unrelated surgical procedures during the postoperative period.

STEPS IN ASSIGNING SURGERY MODIFIERS
8-36 STEPS IN ASSIGNING SURGERY MODIFIERS 1. Read all the documentation. 2. Determine whose service is being coded. 3. Make sure the code description for the CPT code does not already include identifiers. 4. If the CPT code description includes several body parts in one code description do not assign an anatomic modifier. 5. If a procedure is performed separately from the complex procedure, a -59 may be applicable. 6. Determine the time frame within which a service was performed and consider using -24, -58, -76, -77, -78, -79. 7. If an assistant surgeon or other provider performed a portion of the procedure consider using -80, -62, -66, -80, -81, -82. 8. For Medicare patients refer to HCPCS as well as CPT. 9. Sequence modifiers
