Impact

Clinical: Impairs treatment planning, Regulatory: Non-compliance with documentation standards, Financial: Potential for claim denials

Mitigation

Use specific language in documentation, Include context and triggers

Using R45.6 alone when an underlying condition exists

Impact

Reimbursement: Potential claim denials or reduced reimbursement, Compliance: Non-compliance with CMS sequencing guidelines, Data Quality: Inaccurate representation of patient condition

Mitigation

Code the underlying condition first, then R45.6 as secondary.

Sequencing errors

Impact

Incorrect sequencing of codes can lead to audit flags.

Mitigation

Follow CMS guidelines for sequencing mental health and behavioral codes.
