P11.5
BillableBirth injury to spine and spinal cord
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is P11.5 an HCC code?
Yes. P11.5 maps to Spinal Cord Disorders/Injuries under the CMS-HCC V28 risk adjustment model.
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for P11.5
For P11.5 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- 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
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed P11.5 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
P11.5 is the ICD-10-CM diagnosis code for birth injury to spine and spinal cord. Injury to the baby's spine or spinal cord that occurs during the birth process, which may result in temporary or permanent neurological effects. P11.5 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering birth trauma (p10-p15).
Under the CMS-HCC V28 risk adjustment model, P11.5 maps to Spinal Cord Disorders/Injuries (HCC 182) with a community, non-dual, aged base RAF weight of 0.282. P11.5 was not retained as a payment HCC under the older V24 model, so V28 introduced or recategorized it during the 2024–2026 phase-in. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Document the specific location of the spinal injury (cervical, thoracic, lumbar) if documented in the medical record. Because P11.5 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for P11.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the specific location of the spinal injury (cervical, thoracic, lumbar) if documented in the medical record
- •Distinguish between spinal fractures and spinal cord injuries, as they may require different codes or additional specificity
Clinical Significance
Spinal cord birth injury represents severe trauma that can result in permanent neurological deficits including paralysis and sensory loss. This condition requires immediate neurological assessment and may necessitate specialized neonatal intensive care with long-term rehabilitation planning for motor and sensory impairments.
Documentation Requirements
- ✓Evidence of spinal cord or vertebral injury from birth trauma
- ✓Neurological examination documenting motor/sensory deficits
- ✓Imaging studies showing spinal injury when available
- ✓Documentation of difficult delivery or birth complications
- ✓Assessment of injury level and neurological impact
- ✓Exclusion of other causes of neonatal neurological deficits
- ✓Treatment plan including positioning and supportive care
- ✓Consultation with pediatric neurology or neurosurgery
Commonly Confused Codes
- •P14.1 — Erb's paralysis due to birth injury (brachial plexus vs spinal cord)
- •P14.0 — Klumpke's paralysis due to birth injury (peripheral vs central injury)
- •P11.1 — Other specified brain damage due to birth injury (brain vs spinal)
- •G82.20 — Paraplegia, unspecified (acquired paraplegia vs birth injury)
- •Q05.9 — Spina bifida, unspecified (congenital vs traumatic)
