💥About CPT

Introduction

The Current Procedural Terminology (CPT®) code set is a medical code set maintained and copyrighted by the American Medical Association (AMA) through its CPT Editorial Panel. It is used to report medical, surgical, radiology, laboratory, anesthesiology, and evaluation & management (E/M) procedures and services performed by physicians, other qualified healthcare professionals, and facilities.

CPT was first published in 1966 and is updated annually, with new editions released each fall and effective January 1 of the following year. It is one of the HIPAA-designated code sets required for electronic healthcare transactions and works alongside ICD-10-CM (diagnosis) and HCPCS Level II (supplies, drugs, non-physician services) to form a complete claim.

This note reflects the 2026 CPT code set, effective for dates of service January 1, 2026 through December 31, 2026.

Structure and Format

CPT codes are 5 characters, with the following characteristics:

• Category I codes: 5 numeric digits (e.g., 99213, 52630). These represent the bulk of the code set — procedures and services consistent with contemporary medical practice.
• Category II codes: 4 numeric digits followed by the letter F (e.g., 3044F). These are supplemental tracking codes for performance measurement; they are not billable and carry no RVU value.
• Category III codes: 4 numeric digits followed by the letter T (e.g., 0499T). These are temporary codes for emerging technology, services, and procedures that have not yet met the criteria for a Category I code. They are billable but often carry payer-specific coverage restrictions.
• PLA codes: 4 numeric digits followed by the letter U (e.g., 0001U). Proprietary Laboratory Analyses codes for specific, brand-name lab tests.
• Alpha-numeric/administrative codes: A small number of codes use a leading letter (e.g., the CPT F-code hearing device family). These follow AMA-specific formatting outside the standard 5-digit numeric structure.

Code structure:

• Section: CPT is organized into 6 major sections — Evaluation & Management (99202–99499), Anesthesia (00100–01999), Surgery (10004–69990), Radiology (70010–79999), Pathology & Laboratory (80047–89398), and Medicine (90281–99607).
• Subsection: Sections are divided by body system or service type. Example: “Urinary System (50010–53899)” within Surgery.
• Subheading/Category: Further divides by anatomic site or procedure type. Example: “Bladder (51701–52700).”
• Code descriptor: The full narrative description of the service, which may include semicolons — text before the semicolon is a “common portion” shared by indented codes beneath it. Example: “52000 Cystourethroscopy (separate procedure).”
• Add-on codes (+): Report additional intra-service work performed in conjunction with a primary procedure; never reported alone. Example: “+52354 Cystourethroscopy… with laser or electro coagulation of tissue (list separately in addition to code for primary procedure).”
• Unlisted codes: Each subsection has an “unlisted procedure” code used when no specific code describes the service; these require supporting documentation and often a special report to the payer.
• Modifier “-51 exempt” (Ⓝ) and “modifier -63 exempt” symbols: Appendix E and F list codes exempt from certain modifiers.

Common Symbols and Abbreviations

• ● (bullet): New code for the current edition.
• ▲ (triangle): Revised code descriptor.
• + (plus): Add-on code, always reported with a primary procedure.
• ⊘ (circle with slash): Modifier -51 exempt.
• # (number sign): Out-of-numerical-sequence code (resequenced).
• Ⓐ (facility-only bubble): Codes requiring imaging/facility supervision documentation.
• NCCI/CCI: National Correct Coding Initiative — CMS-maintained edit pairs that determine which code combinations can/cannot be billed together without a modifier.
• RVU: Relative Value Unit — the basis for Medicare Physician Fee Schedule reimbursement (work, practice expense, malpractice components).
• Global period: The 0/10/90-day post-op window during which follow-up care related to the procedure is bundled into the original payment.

What’s New in 2026

The 2026 CPT code set, released by the AMA and effective January 1, 2026, introduces 418 total editorial changes: 288 new codes, 84 deletions, and 46 revisions — the largest categories of new codes coming from proprietary laboratory analyses (27%) and Category III emerging-technology codes (27%).The 2026 code set includes 84 deletions, 46 revisions, and 288 additions across evaluation & management, surgery, radiology, pathology & laboratory, medicine, and Category III services, with proprietary laboratory analyses and Category III codes for emerging medical services each accounting for 27% of the new codes.

2026 CPT Coding Highlights

SUMMARY

DETAILS — Specialty Highlights (Urology, Ophthalmology, OTO)

Urology

• Prostate biopsy restructuring: The single legacy code 55700 was deleted and replaced with nine new codes (55707–55715) differentiating biopsy technique and approach. Coders should crosswalk any deleted-code claims and confirm documentation captures approach (transrectal/transperineal/in-bore), guidance modality (ultrasound/MRI-fusion), and lesion count for targeted biopsies.
• BPH procedures: New combination-balloon code 52443 and new robotic waterjet resection code 52597 expand options beyond existing UroLift/Rezum-type codes — confirm which specific device/technique was used before code selection, since these are technique-specific, not interchangeable.
• Documentation tip: Payers are increasingly denying claims for bundled imaging billed separately alongside the new prostate biopsy codes, since imaging guidance is included in the code descriptor.

Ophthalmology

• Dark adaptation testing: Revised 92284 now explicitly specifies “diagnostic” use; new screening code 92288 should be selected when the service is a screening measurement rather than a full diagnostic workup with interpretation and report.
• New Category III codes (0996T, 1010T, 1012T) cover capsular bag prosthesis fixation, retinal-based eye-tracking assessment, and motorized ab interno trephination — verify payer coverage policies before billing, as Cat III codes frequently carry non-coverage or investigational designations.

Otolaryngology (Audiology/Hearing Devices)

• Complete overhaul of hearing device coding: The 92590–92595 family is gone; the new 92628–92642 family is time-based and pathway-specific (candidacy evaluation → selection → fitting → verification/follow-up). Update templates to capture time spent at each stage, since the new structure ties directly to time thresholds similar to E/M or RPM coding.
• New Category III codes for fully implantable active middle ear hearing implants and cryolysis therapy for sleep apnea (soft palate/base of tongue/lingual tonsils) reflect continued OTO device innovation — confirm FDA/payer status before assigning.

Implementation Notes for 2026

• Deleted codes submitted on/after January 1, 2026 will deny on first pass and require manual correction — build a crosswalk of any deleted codes routinely used in Urology, Ophthalmology, and OTO workflows.
• Payer adoption of new Category I codes may occur on a delayed timeline relative to the AMA’s January 1 effective date, so verify payer-specific recognition prior to claim submission.
• HCPCS Level II modifiers (including -LT/-RT) are updated quarterly by CMS, independent of the annual CPT cycle — recheck modifier guidance separately from the CPT update.
