# The CMS, who maintain these codes, describe the format as:- # "HCPCS Level II codes (also known as alpha-numeric codes) consist of a single alphabetical letter followed by 4 numeric digits." # (https://www.cms.gov/medicare/coding-billing/healthcare-common-procedure-system) # NOTE: This regex will not identify HCPCS Level I codes (AKA CPT codes) # Also, some sources say the single letter ranges only from A-V (this regex follows A-Z) # Finally, this regex does not match procedure modifiers, which are 2 digit codes that follow a HCPCS code (with hyphen). # (https://www.aapc.com/resources/what-are-medical-coding-modifiers) # A separate regex has been created on regex101 supporting these modifiers # Genuine codes E8015 A6410 C5278 G2102 M1221 V2623 V2756 c5278 g2102 m1221 v2623 v2756 # Should fail EE8015 6410 E641O [6410 _6510 g212 C52789
