5.6.2.4 Level II

The following is information about CMS (HCPCS) codes:

•	CMS (HCPCS) provides codes for both physician and nonphysician services that are not contained in CPT (such as ambulance, durable medical equipment (DME), prostheses, and some medical codes).

•	Updating of HCPCS codes is the responsibility of the CMS Maintenance Task Force.

•	The codes are all alphanumeric, consisting of a single alpha character (A–V) followed by four numeric digits.

The single alpha character signifies the following:

Character	Description
A	Supplies, ambulance, chiropractic
B	Enteral and parenteral therapy
D	Dental
E	DME and oxygen
H	Rehabilitation services
J	Drugs (administered other than orally)
K	ICD‑9‑CM surgery (informational only)
L	Orthotic and prosthetic procedures
M	Medical
P	Laboratory
Q	Temporary procedures
R	Radiology
T	Diapers
V	Vision and hearing services (nonphysician); speech/language pathology services (nonphysician)

HCPCS codes are used by all the CSHCN Services Program providers to identify the procedures they perform.

Exception: Inpatient facility charges submitted on a UB-04 CMS-1450 paper claim form or equivalent electronic claim format must be billed using revenue codes.
