DESCRIPTION OF CPT

• CPT is a coding nomenclature that allows medical procedures to be transformed to numbers• CPT is based on professional services provided by healthcare providers such as physician, nurse practitioners and physician assistants• CPT services include office visits, surgery, laboratory, radiology, pathology, anesthesia and medical procedures

3

CPT BACKGROUND• CPT was developed by the American Medical Association (AMA) in 1966.• CPT is still currently maintained by the AMA• CPT code sets

– HCPCS level I (Healthcare Common Procedure Coding System)

• CPT codes maintained by AMA– HCPCS level II

• HCPCS codes maintained by Federal Government

4

PURPOSE OF CPT• Reimburse physician services• Trending services provided nationally• Future coding and reimbursement planning• Benchmarking facilities, costs and services• Measuring quality of care and patient outcomes nationally

5

ALL CPT CODES MUST BE:• Commonly performed by physicians across the nation• Consistent with mainstream medical practice• Approved by the AMA CPT Editorial Board

6

ORGANIZATION OF CPT • Each code is followed by a unique code descriptor explaining the service• More than 8,000 unique CPT codes• CPT codes are 5 digits long• CPT manual includes parenthetical notes

7

INTRODUCTION TO CPT• Category I codes are permanent codes• 6 Sections of Category I codes-each with a set of guidelines at the section beginning

– Evaluation and Management (E/M)– Anesthesia– Surgery– Radiology– Pathology/Laboratory– Medicine

8

EVALUATION AND MANAGEMENT SECTION

• Code Ranges 99201 - 99499• Cover physician services that are performed to determine the best course for patient care

9

ANESTHESIA SECTION• Code Ranges 00100 – 01999• Used to report anesthesia services performed or supervised by a physician• Codes include routine anesthesia care

– Pre-op, intra-op, post-op

10

SURGERY SECTION• Largest section in the CPT book• Code ranges 10021 – 69990• Divided by body systems

– Integumentary, musculoskeletal, respiratory, digestive, cardiology, urinary, male/female, nervous, auditory/ocular

• Codes are for a surgical package– Pre-op, intra-op, post-op

11

RADIOLOGY SECTION• Code Ranges 70010 – 79999• Used to report radiological services performed or supervised by a physician• Codes are selected based on the body part and number/type of view

12

PATHOLOGY/LABORATORY SECTION• Code Ranges 80048 – 89356• Cover services provided by physicians or technician supervised by physicians• Complete procedure includes:

14

CATEGORY II CODES• Used to track physician performance in measuring and monitoring patient care• Are alphanumeric codes, start with 1 letter then followed by 4 numbers• Improve quality of care but are not “billable”

15

CATEGORY III CODES• Introduced in 2002• They are used to report new technology, services or procedures that do not currently have a CPT code assigned• Located directly after the Category II codes• Allow researchers to track emerging technology

32

HOW TO ASSIGN CPT CODES AND MODIFIERS

• Step 1: review the complete medical documentation• Step 2: Abstract the medical procedures that should be coded• Step 3: Identify the main terms and related terms• Step 4: Locate the terms in the CPT index• Step 5: Review the codes, descriptors and notes

33

HOW TO ASSIGN CPT CODES AND MODIFIERS

• Step 6: Verify the code against the documentation• Step 7: Assign codes for all significant services• Step 8: Assign modifiers, if appropriate• Step 9: Check all possibilities before final code assignment
