Speech-language pathology billing
Speech therapy billing for the codes that don't follow PT rules
Speech-language pathology billing differs from PT and OT: many core SLP treatment codes are untimed and billed once per session, and evaluation codes are specific to the type of assessment. SLP services still require the therapy discipline modifier and a plan of care under Medicare.
Built for
- Pediatric and adult speech therapy practices
- Rehab groups with SLP services
Where speech therapy revenue usually gets stuck
- Untimed vs timed codes
- Treatment of speech, language and voice (92507) is untimed; billing it in units causes denials.
- Evaluation selection
- Separate codes exist for different evaluation types, such as speech sound production and language comprehension.
- Pediatric coverage
- Coverage for developmental speech delays varies by plan and state mandates.
