What is ICD-10 code S98.139D?

S98.139D is the ICD-10-CM diagnosis code for Complete traumatic amputation of one unspecified lesser toe, subsequent encounter. It belongs to the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88). S98.139D is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. S98.139D is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Is S98.139D billable?

Yes. S98.139D is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. S98.139D is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does S98.139D map to under V28?

S98.139D has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for S98.139D?

S98.139D has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for S98.139D?

S98.139D has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports S98.139D?

S98.139D is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Is S98.139D an HCC code?

S98.139D is not in the CMS-HCC V28 or V24 community payment model. S98.139D has a separate mapping under the CMS-HCC ESRD model (HCC 189 (Amputation Status/Lower Limb/Amputation Complications)); the applicable result needs member context.

HCC Category Mapping

ESRDHCC 189, Amputation Status/Lower Limb/Amputation Complications

Not separately weighted

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. Weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for S98.139D

For S98.139D, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.

MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
EEvaluate: test results, medication response, or physical findings reviewed by the provider
AAssess: explicit mention in the assessment or plan with acknowledgment of status
TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

What This Code Means

S98.139D is the ICD-10-CM diagnosis code for complete traumatic amputation of one unspecified lesser toe, subsequent encounter. S98.139D sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering injuries to the ankle and foot (s90-s99).

S98.139D has no mapping under the CMS-HCC V28 or V24 community payment models. S98.139D has a separate mapping under the CMS-HCC ESRD model (HCC 189 (Amputation Status/Lower Limb/Amputation Complications)); the applicable result needs member context. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

S98.139D is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models. It does map under the CMS-HCC ESRD model, and that result depends on member context rather than on the V28 community model. Do not assign risk adjustment value from this page when no source-backed mapping is shown. Coders should check the current model files and select only the specificity supported by the provider documentation.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for S98.139D sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
