Psychiatry

E&M complexity, medication management, and psychotherapy add-ons — billed correctly every time.

CPT 99213CPT 99214CPT 99215CPT 90833CPT 90836CPT 90838MDM ComplexityParity Law
  • E&M level selection (99213–99215) based on medical decision making complexity
  • Psychotherapy add-on codes (90833, 90836, 90838) appended correctly to E&M visits
  • Medication management documentation requirements — coding compliance before submission
  • Parity law compliance and prior auth management for psychiatric services
Top Revenue Risks We Prevent

E&M downcoding — 99215 billed but documentation only supports 99213, triggering audits

Psychotherapy add-ons (90833/90836/90838) missed entirely — significant lost revenue per visit

Parity violations on psychiatric prior auths — more restrictive criteria than medical equivalents

Telehealth prescribing documentation gaps creating billing compliance risks

Specialty 01C

Applied Behavior Analysis (ABA Therapy)

ABA billing is unlike any other specialty — high auth volume, unit-based coding, and aggressive payer scrutiny.

CPT 97151CPT 97152CPT 97153CPT 97154CPT 97155CPT 97156CPT 97158BCBA Supervision
  • Full ABA CPT code family (97151–97158) — correct provider type, supervision level, unit billing
  • Prior auth management for initial assessments, treatment plans, and ongoing services
  • BCBA vs. RBT billing distinction — supervision ratios and direct service codes applied correctly
  • Parity law enforcement for ABA — aggressive action on non-compliant payer limitations
Top Revenue Risks We Prevent

Wrong provider type billed — BCBA vs. RBT distinction causes mass claim rejections

Auth expirations during high-volume service weeks — one lapsed auth = dozens of unbillable sessions

Unit rounding errors on time-based ABA codes — small errors multiply across hundreds of claims

Parity non-compliance by insurers — visit limits and hour caps that violate federal law

CPT 93000CPT 93306CPT 93451MIPS/QPPBundling RulesPeer-to-Peer

  • MIPS/QPP reporting support and prior auth management for high-cost imaging
  • Peer-to-peer review coordination when insurers push back on medical necessity

Top Revenue Risks We Prevent

Echo/stress test bundling errors — payers reduce payment when codes are billed incorrectly

MIPS reporting failures causing Medicare payment adjustments (-9% penalty risk)

Medical necessity denials on cath procedures — require peer-to-peer to recover
