Prior authorization — none stated

No prior authorization requirements are stated in the extracted code listing or surrounding text; the document provides ICD‑10 diagnosis codes with coverage flags but does not include any PA instructions in these chunks.

Prior authorization — no PA requirements specified here

This portion of the document is a code listing and shows coverage indicators for ICD‑10 entries; it does not specify any prior authorization requirements for services tied to these codes.

Prior authorization not specified — ICD‑10 listing only

The excerpt lists ICD‑10‑CM codes (including O35.* series) with Y/N applicability flags but contains no prior authorization instructions associated with those codes.

Diagnosis coding — no PA instructions in this extract

The code listings include diagnosis coding guidance (specific O‑series codes and fetus/trimester modifiers) but do not contain any instructions that a particular code requires prior authorization.

Prior authorization — not specified in this excerpt

No prior authorization requirements are stated in the excerpt; the text presents ICD‑10 entries with coverage indicators and no authorization workflow.

Prior authorization — none specified in these chunks

The provided chunks are an ICD‑10 code appendix and do not include any prior authorization conditions or requirements for the listed codes.

Step therapy — none present

No step therapy rules or requirements are present in these code listing chunks; the document lists diagnosis codes and coverage indicators only.

Step therapy — no step therapy rules in code listing

The ICD‑10 code tables and mappings in this excerpt do not define any step therapy protocols or prerequisite treatments.

Provider actions — none specified in this excerpt

These chunks do not contain explicit provider actions; they present ICD‑10 code listings and coverage indicators without required next steps or actions for providers.

Provider actions — no explicit actions listed

No explicit provider actions are described in these extracted code-list chunks; the content focuses on code descriptions and Y/N coverage flags.

Step therapy — not present in this excerpt

This excerpt contains no step therapy requirements or sequencing rules; it is limited to diagnosis codes and coverage indicators.

Step therapy — no requirements described

The code listings in these chunks do not describe any step therapy or prior step requirements for services.

Provider action / documentation — none specified

No provider documentation requirements are specified in the extracted sections; the text provides ICD‑10 code entries and coverage indicators only.

Documentation requirements — none stated; ICD‑10 entries only

These chunks list ICD‑10 codes only and do not state any documentation requirements for claims beyond using the appropriate diagnosis codes.

Ensure correct code granularity and current code version

Several entries note historical 6th/7th digit requirements or retired forms (for example, O34.21 marked 'Ended 9/30/2016 - Req 6th Digit'), indicating providers must use the current valid code granularity when selecting diagnosis codes.

• Confirm and bill with the current valid ICD‑10‑CM code variant and required digit level.

Select appropriate O35.* code variant

Select the specific O35.* code variant that matches the clinical scenario (fetus ordinal/number and trimester are encoded in the seventh‑digit/fetus modifiers); the listing includes multiple fetus‑specific variants.

• Use the fetus-specific modifier (fts1–fts5) and trimester variant that reflect the patient’s clinical details.

Documentation requirements — none provided in this excerpt

The extracted chunks do not provide documentation instructions (they are code listings); no additional documentation requirements are stated here.

Billing documentation note — use listed ICD‑10 codes with 'Y' indicator

The code tables show each listed ICD‑10 diagnosis with a 'Y' coverage indicator; providers should use the listed ICD‑10 codes (those marked Y) when coding claims for corresponding conditions.

• Bill using the ICD‑10 code variant shown with Covered? = Y for the condition being treated.

Denial risk — none specified for listed codes

The code listing does not identify provider actions that would trigger denial; most codes in these chunks show 'Covered? = Y' rather than denial criteria.

Denial risk — no explicit provider-triggered denial actions listed

The code appendix is a mapping of diagnosis codes and does not list specific provider actions that would cause denial; it focuses on coverage flags for codes rather than denial workflows.

Denial risk — non‑applicable codes (Y = N) may cause denial

Some older or non‑applicable code forms are marked Y = N (not applicable) in the listing (for example O33.7 was Y = N in its short form), meaning claims submitted with those specific non‑applicable codes may be denied or are not valid for use.

• Avoid billing with codes explicitly marked Y = N (not applicable) or 'Ended' in the listing.

Denial risk — ended code variants may not be accepted

Certain O35.0XX* entries are marked 'Ended 9/30/2022' (O35.0XX0, O35.0XX1, O35.0XX2, O35.0XX3, O35.0XX4, O35.0XX5, O35.0XX9); billing with these ended code variants after their end date may result in denial because they are retired.

• Do not use O35.0XX* variants that are noted as 'Ended 9/30/2022'.

Provider actions — no additional actions in this excerpt

These chunks present diagnosis codes with coverage indicators (Y = Y) and do not set out any additional provider actions or denial triggers beyond correct code selection.

ICD‑10 code coverage indicators — codes shown with 'Y' (coverage)

The listed ICD‑10 codes are shown with a 'Y' coverage indicator in the appendix; the document does not include authorization or denial workflow instructions in these chunks.
