HCPCS Code S0201: Partial Hospitalization Services, Less Than 24 Hours, Per Diem

The difference between HCPCS code H0035 and S0201 lies mainly in their usage and payer acceptance: both codes represent partial hospitalization services (PHP) for mental health treatment less than 24 hours per day, with H0035 being the more commonly used and accepted code by Medicare, Medicaid, and many private insurers, while S0201 is an alternate code often used by some private insurers but generally not accepted by Medicare or Medicaid.

The HCPCS Level II code set is used primarily to identify products, supplies, and non-physician services that are not covered by CPT (HCPCS Level I) codes. It includes alphanumeric codes for items like ambulance services, durable medical equipment, prosthetics, and certain medical services, serving as a standardized national system maintained by CMS for billing and claims submission.

The HCPCS codes specifically for colectomy are not the primary codes used; instead, colectomy is generally coded using CPT codes that denote the type and approach of the surgery, such as 44210 for total abdominal colectomy. However, HCPCS codes like G9711 or M1295 may relate to patients with a history of colectomy or colorectal cancer for documentation or quality measures purposes, but the actual colectomy procedure is reported with CPT codes.
