Quick Explanation
This denial code indicates that the application of a hot or cold pack (typically CPT 97010) was billed as a skilled physical therapy service, which payers often classify as a non-skilled, routine modality that does not require the expertise of a licensed therapist. Because these passive modalities can be performed safely by patients or non-licensed personnel, insurers generally bundle them into other primary therapy services or deny them as non-covered.
Common Causes for PT15
Denials with code PT15 typically happen for the following specific reasons:
- Billing CPT code 97010 (hot/cold pack) as a standalone skilled therapy service without concurrent active, skilled interventions.
- Failure to adhere to CMS or commercial payer guidelines that classify hot/cold pack applications as bundled or non-covered services.
- Lack of documentation demonstrating that the patient's condition required the specialized skill of a therapist to safely apply the thermal modality.
- Billing for passive therapy modalities that do not meet the definition of medically necessary, active restorative treatment.
How to Prevent PT15 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Bundle the cost of hot/cold pack applications into the primary active therapy codes rather than billing CPT 97010 separately.
- Configure billing system edits to automatically flag or bundle CPT 97010 when submitted alongside primary skilled codes.
- Educate clinical and billing staff on payer-specific Local Coverage Determinations (LCDs) regarding non-skilled passive modalities.
- Ensure clinical documentation clearly differentiates between self-care/passive modalities and active, skilled therapeutic interventions.

Denial Code: PT15 - Hot pack/cold pack billed as skilled therapy
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code PT15: "Hot pack/cold pack billed as skilled therapy".
We are appealing the denial of CPT code 97010 (hot/cold pack application) as we contend that the service rendered met the definition of skilled therapy under CMS and AMA guidelines. In this patient's specific clinical scenario, severe sensory deficits and a high risk of thermal tissue damage necessitated the direct assessment, application, and ongoing monitoring by a licensed physical therapist to ensure safety. The medical documentation clearly demonstrates that this passive modality was clinically necessary as a preparatory step to facilitate active, skilled therapeutic exercises, rather than a standalone, non-skilled service. We request that this claim be re-reviewed and approved for payment based on the documented clinical necessity and the specialized skills required for safe delivery.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
