Insurance Denials & Appeals for SLPs: How to Get Claims Paid

A denial is not a verdict. A large share of denied therapy claims are overturned on appeal, and most of the rest were preventable at the front desk. The skill is knowing which kind of denial you are looking at, because administrative denials and medical-necessity denials need completely different responses.

Read the denial before you write anything

Find the remark and adjustment reason codes on the EOB or remittance advice. They tell you the category:

• Administrative / technical: missing authorization, wrong modifier, eligibility lapse, untimely filing, duplicate claim, wrong NPI or taxonomy. These are usually corrected-claim or reconsideration issues, not appeals.
• Coding: NCCI bundling edits, units exceeding MUE limits, diagnosis not supporting the procedure. Fix the coding if you were wrong; append the correct distinct service modifier if you were not.
• Medical necessity: "not medically necessary," "maintenance therapy," "no significant improvement," "services could be performed by a non-skilled caregiver." These require a clinical appeal letter with records.
• Benefit / coverage exclusion: developmental delay excluded, visit limit exhausted, plan excludes speech therapy. Often an exception request or a redirect to a different funding source rather than an appeal.

The anatomy of a winning appeal letter

1. Identifiers first: patient name, member ID, claim number, dates of service, CPT and ICD-10 codes billed, and the specific denial reason you are appealing.
2. State the ask in one sentence: "We request reconsideration and payment of claim #X for dates of service A through B."
3. Clinical summary: diagnosis, onset, prior level of function, current functional limitations, and the safety or participation consequence of stopping. Make the functional impact concrete: aspiration risk, inability to communicate medical needs, loss of employment, feeding tube avoidance.
4. Objective progress data: a short table of baseline versus current performance. Numbers beat adjectives.
5. Directly rebut the stated reason. If they said "no improvement," show the data or invoke maintenance coverage under Jimmo. If they said "could be done by a caregiver," explain the specific judgments the SLP made — cue fading, task grading, safety decisions, instrumental findings.
6. Cite authority: the plan's own medical policy, the Medicare benefit policy manual, ASHA practice portal guidance, or peer-reviewed evidence for the approach used.
7. Attach the records that prove it: evaluation, plan of care with certification, progress reports, daily notes for the denied dates, instrumental study reports.

Levels of appeal

Commercial plans typically offer an internal reconsideration, then a formal first-level and second-level appeal, then an external independent review. A peer-to-peer phone review with the plan's medical director is often available and is frequently the fastest win — request it as soon as a medical-necessity denial lands.

Medicare has five levels: redetermination by the MAC (within 120 days of the initial determination), reconsideration by a Qualified Independent Contractor, Administrative Law Judge hearing (with a minimum amount in controversy), Medicare Appeals Council, and finally federal district court. Each level has its own filing deadline stated on the denial notice — calendar them the day the notice arrives.

Medicaid appeals are state-specific and often include a fair-hearing right for the beneficiary. Families frequently have more leverage than providers do; help them use it.

Prevention beats appeals

• Verify benefits, visit limits, and authorization requirements before the evaluation.
• Track authorization units and expiration dates in a shared tracker, not in someone's head.
• Write skilled-language notes every single visit — see the SOAP note guide.
• Get the plan of care certified on time; see the Part B rules.
• Audit your own top five denial reasons quarterly and fix the process that generates them.
• Know each payer's timely filing window; a great appeal filed late is worth nothing.

When the denial is correct

Sometimes the service genuinely is not covered. Then the job is redirecting the family: early intervention or school services, a Medicaid waiver, a university clinic sliding scale, a state loan or grant program, or a sliding-fee cash rate. Document the counseling — it is part of the episode of care, and abandoning the family is both an ethics and a retention problem.

Appeal rights, deadlines, and coverage policies vary by payer and state and change over time. Confirm the specifics printed on your denial notice.
