What Is CPT Code 97140?

CPT 97140 is used for manual therapy techniques, including mobilization, manipulation, and manual lymphatic drainage.

Why Modifier 59 Is Applied to CPT 97140

Modifier 59 signals that a service is distinct and separate from another performed on the same day. In the case of CPT 97140, it is frequently paired with codes such as CPT 97110 (therapeutic exercise) or CPT 97530 (therapeutic activities). Without modifier 59, insurance payers often bundle these codes together and deny payment.

By applying modifier 59 for manual therapy, providers show that the service was medically necessary, performed on a different body part, or provided during a separate patient encounter.

Key Differences Between Modifier 59 and Other Modifiers

When billing physical medicine CPT 97140, it’s critical to understand how modifier 59 compares to other common modifiers:

• Modifier 59 (Distinct Procedural Service):
  Used to show that 97140 was provided as an independent service, separate from other therapeutic procedures.

• Modifier X modifiers (XE, XS, XP, XU):
  These are CMS-recognized subsets of modifier 59, providing more specific distinctions. For example:

  • XE – Separate encounter

  • XS – Separate structure or body part

  • XP – Separate practitioner

  • XU – Unusual, non-overlapping service

• Modifier 51 (Multiple Procedures):
  Applied when multiple procedures are performed during the same session, but it does not distinguish distinct procedural services in the same way as modifier 59.

For therapy service billing rules, modifier 59 is often the most reliable tool to prevent claim denials when CPT 97140 overlaps with other therapy codes.

CPT 97140 Billing Guidelines

When applying CPT 97140 billing guidelines, providers should keep the following in mind:

• Document the specific body region where manual therapy was provided.

• Record the time spent delivering the therapy (each unit = 15 minutes).

• Clearly explain why the service was separate from other procedures performed that day.

• Use modifier 59 (or X modifiers when accepted) only when necessary. Overuse of modifier 59 can trigger audits.

For example, if a provider delivers therapeutic exercises (97110) for the right shoulder and manual therapy (97140) for the left shoulder, modifier 59 should be added to 97140 to show that both services are distinct.
