Level II of the HCPCS is a standardized coding system that is used primarily to identify products, supplies, and services not included in the Level I CPT codes.

These include items such as ambulance services and durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) when used outside a physician's office.

Because Medicare and other insurers cover a variety of services, supplies, and equipment that are not identified by CPT codes, the level II HCPCS codes were established for submitting claims for these items.

Level II codes are also referred to as alpha-numeric codes because they consist of a single alphabetical letter followed by 4 numeric digits, while CPT codes are identified using 5 numeric digits.

Examples

x <- c('T1503', 'G0478', '81301', '69641', '0583F', '0779T', NA)

is_hcpcs_level_II(x)
#> [1]  TRUE  TRUE FALSE FALSE FALSE FALSE    NA

x[which(is_hcpcs_level_II(x))]
#> [1] "T1503" "G0478"
