S2S specializes in billing and credentialing for behavioral health practices (therapists, counselors, psychologists, social workers, psychiatrists, and psychiatric nurse practitioners) and for physical and occupational therapy practices. We also bill for ABA therapy, cardiology, podiatry, and home health. We don't guess at codes: we know the CPT nuances, medical necessity triggers, and payer quirks that affect your bottom line.

Parity law denials — insurers illegally applying stricter criteria than medical/surgical benefits
Time-based billing errors — incorrect session length documentation triggering downcoding
Telehealth POS mismatches causing automatic claim rejections
Interactive complexity add-on (90785) being missed — leaving reimbursement unclaimed
E&M complexity, medication management, and psychotherapy add-ons — billed correctly every time.
For psychiatrists and psychiatric-mental health nurse practitioners (PMHNPs), including practices that combine medication management with therapy.
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
Drowning in Plan of Care renewals and auth expirations? We track every one.
For outpatient PT and OT clinics, private practices, and massage therapy services billed alongside them. In Bayonne, Jersey City, Hoboken, or elsewhere in Hudson County? Jennifer can meet in person.
Lapsed Plan of Care authorizations — sessions rendered without valid auth = non-payable claims
GP/GO/GN modifier errors causing claim rejections across every payer
Visits past the annual KX threshold billed without the KX modifier and supporting documentation — denied claims
Massage therapy claims denied for insufficient medical necessity documentation
Behavioral health and PT/OT are where S2S focuses, but the same specialty-level billing, credentialing, and authorization work is available for these practices too.
ABA billing is unlike any other specialty — high auth volume, unit-based coding, and aggressive payer scrutiny.
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
High-dollar procedures require flawless documentation. We make sure the coding matches.
Echo/stress test bundling errors — payers reduce payment when codes are billed incorrectly
Missing prior auths for high-cost imaging — one missed auth on a $3,000 procedure is catastrophic
MIPS reporting failures causing Medicare payment adjustments (-9% penalty risk)
Medical necessity denials on cath procedures — require peer-to-peer to recover
Routine vs. non-routine foot care billing is one of the most denied categories in medicine.
Routine foot care denied without Class Findings — most common denial in podiatry billing
Q-code selection errors on nail care procedures — wrong code = automatic Medicare denial
ABN forms not issued before non-covered services
Custom orthotic DME claims missing HCPCS modifiers
Episode-based payment and OASIS accuracy directly affect your reimbursement. We protect both.
OASIS-E inaccuracies directly lowering clinical grouping scores and PDGM payment rate
RAP submission delays — cash flow gaps when pre-claims aren't submitted in time
Homebound status not sufficiently documented — ADRs and recoupment from Medicare
CMS rule changes not caught in time — billing built on outdated payment models
