HCPCS Code S8990: Physical or Manipulative Therapy For Maintenance Rather Than Restoration

Medicare generally does not cover physical or manipulative therapy services when performed solely for maintenance purposes. Coverage is typically limited to services that are medically necessary for the restoration or improvement of function following injury or illness. Maintenance therapy aimed only at preserving the current condition without expectation of improvement is usually not reimbursed.

Medicare covers chiropractic manipulative treatment (CMT) for spinal subluxation diagnoses, represented by specific ICD-10 codes such as M99.00 to M99.05 (segmental and somatic dysfunction of various spinal regions) and M99.10 to M99.15 (subluxation complex of different regions). These codes must be paired with CMT CPT codes (98940, 98941, 98942) billed with the AT modifier, which indicates active treatment rather than maintenance.

The HCPCS Level II code for a bathtub chair is E0240. This code covers a seat or chair designed for use in a bathtub to assist patients with bathing safely, typically categorized under durable medical equipment.
