Q5: What’s the difference between coding psychiatry and substance abuse treatment?

A: While both fall under behavioral health, they have distinct focuses. Psychiatry coding emphasizes mental health disorder diagnosis coding and psychotherapy procedures. Substance abuse coding focuses on substance use disorder diagnoses, medication-assisted treatment, detoxification services, and group counseling specific to addiction treatment. Many behavioral health coders handle both, but some specialize.

Q6: How often do ICD-10 codes for psychiatric diagnoses change?

A: The ICD-10-CM system updates annually on October 1st. Mental health-related codes are regularly reviewed and updated to reflect clinical practice and DSM-5 alignment improvements. Behavioral health coders must review annual updates and implement changes promptly to maintain compliance and accuracy.

Q7: What should I do if I find a documentation error related to a psychiatric diagnosis?

A: Submit a respectful query to the provider requesting clarification. Frame it professionally, explaining the coding impact of the unclear documentation. Provide specific DSM-5 criteria questions if needed. If the provider confirms the diagnosis as coded, proceed. If they clarify or correct it, code accordingly. Never assume or change documentation without provider input.

Q8: How does telehealth affect behavioral health coding?

A: Telehealth requires specific modifiers (like 95 for synchronous telemedicine services), geographic compliance verification, and documentation of the technology platform used. Telehealth services may have different coding requirements and reimbursement rates than in-person services. Stay current with CMS updates and payer policies regarding telehealth behavioral health services.

Q9: What’s the relationship between medical comorbidities and psychiatric diagnosis coding?
