In re K & L Auto Crushers: How Texas Defense Counsel Discovers Negotiated Medical Rates

In In re K & L Auto Crushers, LLC, 627 S.W.3d 239 (Tex. 2021), the Texas Supreme Court conditionally granted mandamus and ordered the trial court to allow narrowly-tailored discovery of negotiated billing rates and chargemaster data from the plaintiff's medical providers. That decision extended In re North Cypress Med. Ctr. Operating Co., 559 S.W.3d 128 (Tex. 2018), from in-network hospital providers to non-network providers and letter-of-protection (LOP) billed care. For Texas personal injury practice, K&L reshaped how defense counsel develops reasonableness evidence on the medical-expense component of damages.

This article walks through what K&L actually held, how Tex. R. Civ. P. 192's general scope of discovery applies to medical-billing data, how defense counsel uses K&L in practice, the narrow-tailoring requirement the court emphasized, and how plaintiff's counsel responds. It also covers the interaction between K&L's discovery framework and the Haygood v. De Escabedo §41.0105 paid-or-incurred cap.

Answer first

K&L Auto Crushers gave Texas defense counsel a tool to subpoena what medical providers actually accept from insurers and government payors for the same services they billed the plaintiff. The discovery is narrowly tailored — specific CPT codes, specific providers, specific treatment period. The negotiated-rate data becomes evidence of what is "reasonable" under §41.0105 and Tex. R. Civ. P. 192. Reasonableness goes to the jury as a fact question. K&L doesn't change the Haygood v. De Escabedo ceiling on recoverable damages — it gives defense counsel ammunition to argue the recoverable amount is lower than the LOP or chargemaster bill suggests.

The doctrinal anchors are In re K & L Auto Crushers, LLC, 627 S.W.3d 239 (Tex. 2021), Tex. R. Civ. P. 192 (scope of discovery), and In re North Cypress Med. Ctr. Operating Co., 559 S.W.3d 128 (Tex. 2018).

What K&L actually held

The K&L case arose from an ordinary auto-collision personal-injury suit. The plaintiff sought medical-expense damages largely composed of LOP-billed orthopedic care and physical therapy. Defense counsel issued discovery requests seeking the same providers' negotiated rates with major insurers, Medicare, and Medicaid for the specific CPT codes billed. The trial court denied the requests as overbroad and irrelevant. The defendant sought mandamus relief.

The Texas Supreme Court conditionally granted mandamus:

Three doctrinal moves matter:

1. Reasonableness is a fact issue, not a presumption. The chargemaster rate or the LOP rate is not automatically reasonable simply because the provider billed it. Reasonableness is a jury question, and the jury needs evidence on which to decide it.

2. Negotiated-rate data is one form of relevant evidence on reasonableness. What the same provider accepts from an in-network insurer for the same CPT code is probative of what is reasonable for that service in that market.

3. Confidentiality clauses don't override discovery rules. A protective order under Rule 192.6 can manage the confidentiality concern; outright denial of discovery on confidentiality grounds is not permitted.

The scope of discovery under Rule 192

Tex. R. Civ. P. 192.3(a) defines the general scope:

K&L applies that standard to medical-billing data. The court reasoned that since the reasonableness of medical expenses is inherently in issue in any case seeking medical-expense damages, evidence bearing on that reasonableness is relevant under Rule 192.3.

Tex. R. Civ. P. 196 governs the procedural form of the requests. A request for production must describe the documents with reasonable particularity. K&L's narrow-tailoring requirement folds into Rule 196's particularity requirement — a request for "all negotiated rates for all services" lacks the case-specific tailoring K&L authorizes.

How defense counsel uses K&L

In practice, defense counsel issues K&L-style discovery in cases involving:

• Substantial LOP-billed treatment. LOP rates are typically chargemaster-pegged or negotiated upward from the chargemaster. K&L lets defense counsel develop comparison data showing what the same provider accepts from insurers for the same services.

• Out-of-network specialty care. Out-of-network providers bill at chargemaster, and the patient's insurer (if any) pays the out-of-network allowed-amount, which is typically lower than the chargemaster but higher than the in-network negotiated rate. K&L lets defense counsel show the relevant rate spread.

• High-cost imaging or procedural billing. A $4,500 MRI from a freestanding imaging center frequently has a Medicare allowed- amount under $400 and an in-network insurer negotiated rate near $700. The spread becomes evidence the jury considers on reasonableness.

• Multi-provider orthopedic and pain-management billing. Cases with stacked treatment from multiple LOP providers — orthopedic surgeon, anesthesiologist, ambulatory surgery center, physical therapy clinic — generate large bill stacks where K&L discovery has the highest yield for the defense.

The mechanical form is a request for production under Rule 196, sometimes paired with a deposition on written questions to the provider's billing custodian under Rule 200. Protective orders are entered routinely to manage the confidentiality concerns the provider-insurer contracts raise.

The narrow tailoring requirement

The court was explicit that K&L doesn't open the door to unbounded discovery of every rate every provider charges every payor. The mandamus relief was conditional on narrow tailoring. Three dimensions of tailoring matter:

Provider-specific. Discovery is limited to the providers who actually treated the plaintiff. A request for negotiated rates from unrelated providers in the same specialty doesn't satisfy K&L.

Service-specific. Discovery is limited to the CPT codes (or DRG codes for hospital admissions) actually billed in the case. A request for rates on services the plaintiff didn't receive doesn't satisfy K&L.

Time-specific. Discovery is limited to the rates in effect during the plaintiff's treatment period (or a reasonable proxy if rates are revised periodically). Historical rates from a decade earlier or prospective rates from years later don't satisfy K&L.

A motion to compel that doesn't observe these three tailoring dimensions is vulnerable to a Rule 192.4 limitation order or a sustained objection. The plaintiff's response to overbroad K&L requests is typically a motion for protective order tied to the specific dimensions where the request fails the tailoring test.

Claimant-side responses

When defense counsel issues K&L-style discovery, plaintiff's counsel has several response paths:

1. Negotiate the scope. Most K&L disputes resolve through negotiated narrowing — defense counsel agrees to per-provider, per-CPT-code, per-period scope; plaintiff's counsel agrees to facilitate the discovery from the providers without opposing. This avoids the discovery-fight tax of a contested motion.

2. Move for protective order on tailoring. If defense counsel's requests aren't narrowly tailored, plaintiff's counsel files a Rule 192.6 motion for protective order, citing K&L's tailoring language and identifying the specific over-breadth.

3. Develop counter-evidence on reasonableness. Even when K&L discovery proceeds, the plaintiff's response at trial isn't to contest the rate-spread evidence — it's to develop counter- evidence on why the LOP or chargemaster rate is reasonable for the specific case. Treating-provider testimony, market-rate surveys for the specialty, and the patient's specific clinical needs all factor in.

4. Reframe the rate-spread argument. A common plaintiff's counter-argument is that the in-network negotiated rate reflects bulk-discount pricing the insurer extracts in exchange for in-network referral volume — not a fair-market rate available to an individual self-pay or LOP patient. This reframing positions the negotiated rate as an artifact of market power, not a benchmark for reasonableness.

Subsequent appellate treatment

Texas courts of appeals have applied K&L in dozens of decisions since 2021. The pattern is consistent: courts grant or deny mandamus on narrow-tailoring grounds, treating K&L as authority for the discoverability of negotiated-rate data while policing the scope.

Key threads in the post-K&L appellate landscape:

The chargemaster-as-policy distinction. Several courts of appeals have addressed whether a hospital's published chargemaster (the list price for all services, regardless of payor) is itself discoverable, or whether discovery is limited to actual transaction prices. K&L authorized both — the chargemaster establishes what the provider initially billed; the negotiated rates establish what the provider actually accepts. Both bear on the reasonableness inquiry.

The "similarly-situated payor" framing. A common dispute is which insurer's negotiated rate is most relevant. Defense counsel typically seeks the major-insurer negotiated rate (which is the lowest); plaintiff's counsel argues for the out-of-network or single-policy allowed-amount (which is higher). K&L doesn't pick a single benchmark; it makes all of them discoverable, and the jury weighs which is most probative of reasonableness.

The treating-provider-deposition workaround. Some courts have held that K&L discovery doesn't preclude direct deposition testimony from a billing custodian or compliance officer about the provider's rate practices. This gives plaintiff's counsel an alternative path when written discovery is contested — depose the custodian on rate practices and let the testimony develop the comparison-rate evidence.

The interaction with the collateral-source rule. Texas's collateral- source rule (the doctrine that a defendant tortfeasor doesn't get a benefit from the plaintiff's insurance) interacts with K&L in subtle ways. Haygood v. De Escabedo, 356 S.W.3d 390 (Tex. 2011), already narrowed the collateral-source rule for medical-expense recovery; K&L extends the discovery side of that narrowing. Some appellate panels have flagged that the K&L framework essentially nullifies the collateral-source rule's pre-Haygood reach in medical-billing fights — though the rule still applies to non-medical collateral sources (disability insurance, social security, employer-paid leave).

The cumulative effect: K&L is now part of the standard procedural arc in any Texas personal injury case with meaningful medical-expense damages. Practitioners on both sides treat the K&L discovery phase as a routine cost of litigation, not as an exotic tool.

When K&L discovery happens in the case lifecycle

Procedurally, K&L discovery typically lands in one of three windows:

Early case-management discovery (Level 2 cases). In Tex. R. Civ. P. 190.3 Level 2 cases (most personal injury cases under $250,000), discovery can begin from the date of suit and extends through the applicable discovery period. Defense counsel's first set of requests to the plaintiff and to non-party providers typically issues within 30-60 days of answering, before depositions. K&L-style requests are included from the outset when the case obviously involves substantial LOP or out-of-network billing.

Witness-designation discovery. Tex. R. Civ. P. 195.5 governs disclosure of testifying-physician opinions. When the plaintiff designates a treating physician to testify on reasonableness or necessity of medical expenses, defense counsel's K&L-style requests target that specific physician's billing practices and negotiated rates. The discovery is timed to inform the defense's responsive witness designation that follows.

Pre-trial summary-judgment discovery. When defense counsel intends to file a summary-judgment motion challenging the medical- expense damages component (typically on §41.0105 reasonableness grounds), K&L discovery may issue late in the discovery period to build the summary-judgment record. This is rarer because the reasonableness fight is usually fact-bound enough that summary judgment isn't viable.

For most cases, the K&L discovery happens in the early-to-middle case-management window, well before depositions and trial preparation.

§18.001 affidavits and K&L counter-evidence

Tex. Civ. Prac. & Rem. Code §18.001 lets a plaintiff establish a prima facie case for the reasonableness and necessity of medical expenses by serving an affidavit from the treating provider's custodian of records. The affidavit gets the medical bills into evidence without live testimony.

Defense counsel responds with a §18.001 counter-affidavit. The counter-affidavit must be served within 30 days of the plaintiff's affidavit (under §18.001(f)) and must be from a person "qualified by knowledge, skill, experience, training, or education to testify in contravention" of the plaintiff's affidavit.

K&L discovery typically informs the counter-affidavit:

• The negotiated-rate evidence developed through K&L discovery becomes the factual basis for the counter-affidavit's reasonableness challenge.
• The qualified counter-affiant — a billing-practice analyst, a retired hospital chief financial officer, or a healthcare reimbursement consultant — relies on the rate-spread data to testify that the chargemaster or LOP rate exceeds the reasonable market rate for the service.

The §18.001 counter-affidavit framework was tightened by 2019 amendments (House Bill 1693), which narrowed who qualifies as a counter-affiant and required more specific reasoning. K&L's evidence production fits the tightened standard well — the counter-affiant points to actual rate transactions, not abstract market opinions.

Interaction with Haygood §41.0105

The K&L framework operates alongside Haygood v. De Escabedo's §41.0105 ceiling, not in place of it. The structural relationship:

• §41.0105 caps the recoverable amount. What the claimant actually paid or remains legally obligated to pay is the ceiling. Chargemaster excess is non-recoverable as a matter of law.

• K&L provides discovery within the ceiling. Once the recoverable amount is established under §41.0105, K&L lets defense counsel attack the reasonableness of that amount with negotiated-rate evidence.

• Reasonableness is the jury question. The jury can find the recoverable amount fully reasonable, partially reasonable, or fully unreasonable. K&L gives the defense the tools to argue the second or third option; plaintiff's counsel responds with case- specific reasonableness evidence.

For LOP-billed care specifically, the post-Haygood, post-K&L framework means the LOP rate is the §41.0105 ceiling (because it's what the claimant is contractually obligated to pay) but is also exposed to K&L reasonableness attack at trial. The math the jury ultimately runs is: ceiling minus reasonableness adjustment equals the recoverable amount.

A worked example: the $180,000 LOP-billed bill stack

To ground the framework, consider a representative case:

Facts: Rear-end collision in Travis County. Plaintiff sustains disc herniation requiring epidural steroid injections, physical therapy, and ultimately a single-level lumbar fusion. The bill stack totals $180,000:

• Hospital surgical admission: $95,000 (LOP-billed)
• Surgeon's professional fee: $32,000 (LOP-billed)
• Anesthesiology: $14,000 (LOP-billed)
• Imaging (3 MRIs over 14 months): $13,500 (LOP-billed)
• Physical therapy (28 sessions): $14,000 (LOP-billed)
• Pain management (epidural injections, follow-ups): $11,500 (LOP-billed)

The plaintiff has health insurance but elected LOP treatment to preserve the full bill amount under §41.0105's "incurred" prong.

K&L discovery requests. Defense counsel issues narrowly-tailored requests to each provider:

• Negotiated rate the hospital accepts from Blue Cross Blue Shield of Texas for DRG 460 (lumbar fusion, single level) during the treatment year
• Negotiated surgeon's fee schedule for CPT 22612 (lumbar fusion) with United Healthcare and Cigna
• Anesthesiology negotiated rates for the surgical-time anesthesia CPT codes
• Imaging-center negotiated rates for the specific MRI CPT codes
• Physical therapy negotiated rates per session for the relevant CPT codes (97110, 97140, 97530)

Discovery production (typical). Under a Rule 192.6 protective order, the providers produce rate data showing:

• BCBS-negotiated rate for the surgical admission: $38,000
• Surgeon's BCBS rate: $9,500
• Anesthesiology BCBS rate: $4,200
• MRI center BCBS rate: $850 each ($2,550 total)
• PT BCBS rate: $115 per session ($3,220 total)
• Pain management BCBS rate: $4,800

Sum of negotiated rates: ~$62,300. Sum of LOP rates: $180,000. The rate-spread is roughly 65% (LOP rate is approximately 2.9x the BCBS-negotiated rate).

Trial framework. Plaintiff's counsel argues §41.0105 makes the $180,000 LOP rate the recoverable ceiling (the patient is contractually on the hook for that amount), and that the LOP rate is reasonable given out-of-network status, the patient's specific clinical presentation, and the value of LOP-financed care. Defense counsel argues the LOP rate is unreasonable relative to the same providers' in-network rates and asks the jury to award something between $62K and $180K. The jury decides.

This worked example is not legal advice for any particular case — real cases vary on facts, payor mix, and provider rate structures, but the K&L mechanical framework operates in roughly the same shape across most Texas LOP-heavy personal-injury fact patterns. The relevant variables are which providers, which CPT codes, which treatment period, and what the rate-spread looks like in the specific market for the specific specialty.

Strategic takeaways

The practical implications for Texas personal injury claimants:

1. K&L discovery is routine in cases with substantial LOP or out- of-network billing. Your case will see discovery requests for negotiated-rate data if the bill stack is meaningful.

2. The discovery itself is not adversarial in the trial-strategy sense. It's procedural. Protective orders manage confidentiality. Focus on the trial-stage reasonableness fight, not on resisting the discovery itself.

3. Treating-provider testimony is the plaintiff's reasonableness anchor. The provider explaining why the rate is reasonable for the patient's specific clinical picture is the most effective counter-evidence to negotiated-rate spread data.

4. K&L-aware case selection matters. Cases with bill-stacks composed entirely of in-network insured care have minimal K&L exposure (the insurer already paid the negotiated rate). Cases with heavy LOP, out-of-network, or self-pay billing have larger K&L exposure. Plaintiff's counsel evaluates this at intake.

Most Texas personal injury cases — including those subject to K&L- style discovery — are handled on contingency, so claimants don't face out-of-pocket cost for the discovery fight.
